Coke Oven Battery (Gunfire)

[0087] Referring now to the figures, the following description should be taken in view of FIGS. 1-2, 4-5 and 7-8, as these illustrations generally illustrate a cross-sectional view of a coke oven battery and a partial perspective of the same, respectively. Specifically, FIGS. 1 and 2 generally illustrate a coke oven battery having the first embodiment of the present invention therein (corbel 100), where FIGS. 4 and 5 generally illustrate a coke oven battery having the second embodiment of the present invention therein (corbel 200), and FIGS. 7 and 8 generally illustrate a coke oven battery having the third embodiment of the present invention therein (corbel 300). The aforementioned illustrations generally depict the same components of a coke oven battery less structural differences provided by the alternative structural configurations of the various embodiments of the present invention. It should be noted that these illustrations of coke oven battery 10 are merely exemplary and one having ordinary skill in the art would understand that FIGS. 1-2, 4-5 and 7-8 are merely representative to illustrate the structural benefits of utilizing corbels 100, 200, and 300 therein.

[0088] FIGS. 1, 4, and 7 are cross-sectional views of coke oven battery 10, in accordance with corbels 100, 200, and 300, respectively. Coke oven battery 10 generally comprises regenerator 20 and one or more ovens 34.

[0089] Regenerator 20 comprises a plurality of piers or pillars 22, which are spaced apart to form regenerator regions 24. In some embodiments, each of pillars 22 comprise a plurality of bricks, modules, and/or blocks. Foundations 26 sit atop pillars 22. Foundations 26 generally support corbels 100, 200, and 300either directly, or indirectly. Typically, foundation 26 comprises a plurality of bricks, modules, and/or blocks, i.e., a variety of structural components. In some embodiments, foundation 26 comprises a plurality of blocks arranged in a plurality of tiers, for example, two tiers T1 and T2 as shown in FIGS. 1 and 4, or four tiers T1-4 as shown in FIG. 7.

[0090] Corbels 100, 200, and 300 are arranged on top of pillars 22 and support the oven section of coke oven battery 10. Specifically, corbels 100, 200, and 300 support floor 28, heating walls 30, and coal placed in ovens 34, allowing air to flow between flues 32 and regenerator 20, and also allowing gas to be injected into flues 32. For example, gas is injected into corbels 100, 200, and 300 horizontally via horizontal through-bores 105, 205, and 305 of gunblock sections 101, 102, and 103, respectively, and flows vertically through vertical through-bores 110 and 42 (of corbel 100, where vertical through-bore 42 is not a component of corbel 100 but is in fluid communication with vertical through-bore 110), 210A and 210B (of corbel 200), 310A and 310B (of corbel 300) into flues 32. As discussed herein, corbel 100 may have a pair of vertical through-bores, 110A and 110B (as shown in FIGS. 2 and 3C), which are in fluid communication with vertical through-bores 42 of coke oven battery 10 (shown in FIG. 2). Air flows up through channels 40, channels 250 (of corbel 200) and/or 350 (of corbel 300) and into flues 32 where it mixes with the fuel and combusts to heat heating walls 30, thus cooking the coal arranged in ovens 34 transforming it into coke. Exhaust gasses are created from such combustion, these hot exhaust gases may flow down through channels 40 (of coke oven battery 10 when corbel 100 is used therein), 250 (of corbel 200) and 350 (of corbel 300) and into regenerator regions 24, thereby preheating the incoming gas and/or air. Preheating gas and/or air as it flows into flues prior to combustion is desirable because it produces more efficient vaporization and higher combustion efficiency than cold fuel. It should be appreciated and understand by those having ordinary skill in the art that in some arrangements, coke oven battery 10 further comprises shut-off means (not illustrated) operatively arranged to selectively shut off the gas flow through one or more of the vertical through-bores. Since through-bores 110 (of corbel 100), through-bores 110A and 110B (of an alternatively configured corbel 100), 210A and 210B (of corbel 200), 310A and 310B (of corbel 300) are preferably associated with different flues 32, such shut-off means (e.g., valves) allow the operator to control the temperature in each flue 32 and thus ovens 34. Corbels 100, 200, and 300 will be described in greater detail, infra.

[0091] Floor 28 is arranged on and/or engaged with corbels 100, 200, and 300 (either directly or indirectly). Floor 28 is operatively arranged to support the coal in ovens 34. In some embodiments, floor 28 comprises a plurality of blocks. Floor 28 may comprise a plurality of blocks arranged in a plurality of tiers, for example, six tiers T4-9 in FIG. 1, or three tiers T7-9 in FIGS. 4 and 7. Heating walls 30 are arranged on corbels 100, 200, and 300 and/or floor 28 and comprise flues 32 arranged therein. Flues 32 are in fluid communication with through-bores 110 (of corbel 100 via vertical through-bore 42), 210A and 210B (of corbel 200), 310A and 310B (of corbel 300), and channels 40, 250, and 350. Oven ceiling or ceilings 36 are arranged proximate the, or on, top of heating walls 30. Thus, coking ovens 34 are formed by floor 28, heating walls 30, and oven ceiling 36. Battery top 38 is arranged on top of heating walls 30 and may enclose flues 32. In some embodiments, each flue 32 is in fluid communication with one channel (40, 250 and/or 350) and at least one vertical through-bore, for example, vertical through-bores 42, 210A, and/or 310A. In some embodiments, and as shown in FIGS. 4 and 7, each flue 32 is in fluid communication with vertical through-bores 210A or 310A, vertical through-bores 210B or 310B (of an adjacently arranged corbel), and one channel (250 or 350). Specifically, one flue 32 is aligned with, in order in direction D3, vertical through-bore 210B (or 310B)of a first corbel, channel 250 (or 350)of a second corbel arranged adjacently to the first corbel, and vertical through-bore 210A (or 310A)of the second corbel. As discussed supra and shown in FIG. 2, it should be appreciated that corbel 100 may be alternatively arranged with to two (2) vertical through-bores and confine to the aforementioned arrangementless the inclusion of a channel within corbel 100, i.e., channel 40 is not a component of corbel 100 as shown in FIGS. 1 and 2.

[0092] The arrangement of having a gas injection hole on either side of an air injection passageway provides a desirable combustion mixture of air and fuel. In some configurations, as shown in FIGS. 4 and 7, heating walls 30 may be arranged solely on top of corbels 200 and 300, namely, on a top surface. In some embodiments, heating walls 30 may be arranged at least partially on corbels 200 and 300 and at least partially on floor 28. In some embodiments, heating walls 30 may be arranged solely on floor 28.

Corbel: First Embodiment

[0093] The follow description pertains to the first embodiment of the present invention and should be taken in view of FIGS. 1-3D, which illustrate a cross-sectional view of a coke oven battery in accordance with corbel 100, a partial perspective view of the same, a front perspective view, a skeleton perspective view, an alternative embodiment of corbel 100, and a top view of corbel 100 and an adjacent corbel 100, respectively.

[0094] Corbel 100 generally comprises gunblock section 101, base 102, top end 102A, first end 103, second end 104, through-bore 105 having first opening 106 and second opening 107, first side 108, second side 109, vertical through-bore 110. Gunblock section 101 includes the horizontal gas line, through-bore 105, defined by first opening 106 arranged within first end 103 and second opening 107 arranged within second end 104. Vertical through-bore 110 is in fluid communication with through-bore 105 and has an opening arranged within top end 102A.

[0095] First side 108 is defined by tapered portion 120A which extends from base 102. Tapered portion 120A terminates at shoulder 122A. Extending from shoulder 122A is first side 124A of gunblock section 101. Groove 126A is disposed within shoulder 122A is arranged to extend from first end 103 to second end 104.

[0096] Second side 109 is defined by tapered portion 120B which extends from base 102. Tapered portion 120B terminates at shoulder 122B. Extending from shoulder 122B is first side 124B of gunblock section 101. Groove 126B is disposed within shoulder 122B and is arranged to extend from first end 103 to second end 104.

[0097] In an alternative embodiment of corbel 100, illustrated in FIG. 3C, corbel 100 may have first vertical through-bore 110A and second vertical through-bore 110B, where each of through-bores 110A and 110B having openings arranged within top end 102A and are both in fluid communication with through-bore 105.

[0098] In some embodiments, through-bore 105 includes recess 106A and lip 107A, where recess 106A is disposed proximate first opening 106 and lip 107A extends from second opening 107. As generally illustrated in FIG. 3D, lip 107A of corbel 100 is arranged to be seated within recess 106A of adjacent corbel 100creating a more efficient seal of through-bore 105 of corbel 100 and through-bore 105 of adjacent corbel 100, thereby preventing and/or limiting gas leakage therebetween. It should be appreciated that the above-described arrangements of through-bore 105 of corbel 100 and through-bore 105 of adjacent corbel 100 may also apply to corbels 200 and 300 (shown in FIG. 9A)thereby preventing and/or limiting gas leakage therebetween.

[0099] It should be appreciated that an important aspect of corbel 100 is its configuration provides the tiers between foundation 26 and floor 28, specifically the tiers proximate foundation 26 (T3), as well as a portion of tier T4as shown in FIGS. 1 and 2. Specifically, corbel 100 provides tier T3 and a portion of tier T4, in a single, integrally formed block. By providing a portion of tier T4, and foundation 26 (which may be inclusive of tier T3), a stronger and easier connection between corbel 100 and foundation 26 is formed. In some embodiments, base 102 of corbel 100 could also include tiers T1 and T2, thereby eliminating the need for foundation 26, as shown in FIG. 1.

[0100] It should be further appreciated that grooves 126A and 126B provide mating locations for respective protrusions arranged on the lower surfaces of blocks (tier T4) placed on shoulders 122A and 122B, thereby preventing displacement of those blocks in directions D5 and D6, i.e., similar to a tongue and groove connection. In some embodiments, grooves 126A and 126B could have perpendicularly arranged portions extending therefrom, i.e., cross-shaped, further preventing displacement of blocks, arranged thereon, in directions D3-D6.

[0101] It should also be appreciated that tapered portions 120A and 120B of corbel 100, when arranged next to tapered portions 120A and 120b of an adjacent corbel 100, assists in direct air into channel 40 (i.e., air traveling in direction D1). It should also be appreciated that in some embodiments, corbel 100 may not comprise tapered portions 120A and 120B, whereas sides 108 and 109 are substantially planar surfaces which extend down to base 102.

Corbel: Second Embodiment

[0102] The following description pertains to the second embodiment of the present invention and should be taken in view of FIGS. 4-6F, which illustrate a cross-sectional view of a coke oven battery in accordance with corbel 200, a partial perspective view of the same, a front perspective view, a skeleton perspective view, a perspective view of an alternative embodiment of corbel 200, a skeleton perspective view of the alternative embodiment of corbel 200, a perspective view of two abutting corbels 200 having alternating channels, and a top plan view of two abutting corbels 200 having alternating channels, respectively.

[0103] Corbel 200 generally comprises gunblock section 201, base 202, top end 202A, first end 203, second end 204, through-bore 205 having first opening 206 and second opening 207, first side 208, second side 209, first vertical through-bore 210A, second vertical through-bore 210B, and channel 250. Gunblock section 201 includes the horizontal gas line, through-bore 205, defined by first opening 206 arranged within first end 203 and second opening 207 arranged within second end 204. First vertical through-bore 210A and second vertical through-bore 210B are in fluid communication with through-bore 205 and both have openings arranged within top end 202A. Specifically, the openings of first vertical through-bore 210A and second vertical through-bore 210B are located within recesses 230A and 230B arranged within top end 202A, respectively.

[0104] First side 208 is defined by tapered portion 240A which extends from base 202. Tapered portion 240A terminates at first planar end 241A. First planar end 241A terminates at first ledge 242A. Second planar end 243A extends from first ledge 242A. Second planar end 243A terminates at second ledge 244A. Third planar end 245A extends from second ledge 244A is. Third planar end 245A terminates at top end 202A.

[0105] Second side 209 is defined by tapered portion 240B which extends from base 202. Tapered portion 240B terminates at first planar end 241B. First planar end 241B terminates at first ledge 242B. Second planar end 243B extends from first ledge 242B. Second planar end 243B terminates at second ledge 244B. Third planar end 245B extends from second ledge 244B. Third planar end 245B terminates at top end 202A.

[0106] Channel 250 is disposed within first end 203 of corbel 200, having an open portion on first end 203. Channel 250 has two ends, the first end is disposed within recess 230A and the second end is disposed within tapered portion 240A, first planar end 241A, and first ledge 242A of first side 208. It should be appreciated that channel 250 may alternatively be arranged to have its second end disposed within second side 209 (i.e., within tapered portion 240B, first planar end 241B, and first ledge 242B) of corbel 200-as illustrated in FIGS. 6E and 6F. It should be noted that the aforementioned configuration-alternatively arranged channels-may also apply to corbel 300. As generally illustrated in FIG. 6F, the open portion of channel 250 (arranged on first end 203) is arranged to be closed, covered, and/sealed, by second end 204 of adjacent corbel 200 that is abutting first end 203 of corbel 200 having channel 250 therein.

[0107] In some embodiments, channel 250 may not include an open portion disposed within first end 203. As shown in FIGS. 6C and 6D, channel 250 may be disposed within corbel 200. Corbel 200 may be utilized as an end corbel, or bookend, for a plurality of corbels that are abutted and formed together. The aforementioned configuration may also apply to corbel 300.

[0108] It should be appreciated that an important aspect of corbel 200 is its configuration provides the tiers between foundation 26 and floor 28, specifically the tiers proximate foundation 26 (T3 and T4), as well as the tiers proximate floor 28 (T5 and T6)as shown in FIGS. 4 and 5. Specifically, corbel 200 provides tiers T3 through T6, in a single, integrally formed block providing a stronger and easier connection between corbel 200 and foundation 26, and eliminating seams created by individual blocks. Corbel 200 also provides for portions of tiers T7 through T9. In some embodiments, base 202 of corbel 200 could also include tiers T1 and T2, thereby eliminating the need for foundation 26, as shown in FIG. 4.

[0109] Tier T7 is arranged to be supported by first ledge 242A (and/or first ledge 242B). The respective block of tier T7 is specifically arranged to be placed on first ledge 242A (and/or first ledge 242B) and abut second planar end 243A (and/or second planar end 243B), where second planar end 243A prevents the block of tier T7 from moving in directions D5 or D6.

[0110] Floor 28, comprising tier T8 and/or T9, is arranged to be supported by second ledge 244A (and/or second ledge 244B). The respective block, or blocks, of floor 28, are specifically arranged to be placed on second ledge 244A (and/or second ledge 244B) and abut third planar end 245A (and/or third planar end 245B), where third planar end 245A prevents the respective block, or blocks of floor 28 (tier T8 and/or T9) from moving in direction D5 or D6.

[0111] The arrangement of corbel 200 provides for engagement and support of various tiers of floor 28 at different locations. This allows not only for increased support strength of floor 28, but also for easy repair of floor 28. For example, due to loading and unloading of coal/coke from ovens 34, over time floor 28 exhibits damage thereto. Typically, this damage occurs on the top layer of floor, namely, tier T9. The design of corbel 200 (i.e., the support of two or more layers of floor 28) allows for tier T9 to be easily removed and a new tier T9 placed, without having to remove any other tier of floor 28. Since the entirety of floor 28 does not need to be replaced, battery 10 down time and labor cost is saved.

[0112] Since corbel 200 generally comprises tiers T3 through T6 and portions of tiers T7 through T9, existing seams created by the plurality of blocks that once comprised these tiers are eliminated-thereby eliminating potential leak points of gas, and/or heat.

Corbel: Third Embodiment

[0113] The follow description pertains to the third embodiment of the present invention and should be taken in view of FIGS. 7-9B, which illustrate a cross-sectional view of a coke oven battery in accordance with corbel 300, a partial perspective view of the same, a front perspective view and a skeleton perspective view of corbel 300, respectively.

[0114] Corbel 300 generally comprises gunblock section 301, top end 302A, bottom end 302B, first end 303, second end 304, through-bore 305 having first opening 306 and second opening 307, first side 308, second side 309, first vertical through-bore 310A, second vertical through-bore 310B, and channel 350. Gunblock section 301 includes the horizontal gas line, through-bore 305, defined by first opening 306 arranged within first end 303 and second opening 307 arranged within second end 304. First vertical through-bore 310A and second vertical through-bore 310B are in fluid communication with through-bore 305 and both have openings arranged within top end 302A. Specifically, the openings of first vertical through-bore 310A and second vertical through-bore 310B located within recesses 330A and 330B arranged within top end 302A, respectively.

[0115] First side 308 is defined by tapered portion 340A which terminates at first planar end 341A. First planar end 341 terminates at first ledge 342A. Second planar end 343A extends from first ledge 342A. Second planar end 343A terminates at second ledge 344A. Third planar end 345A extends from second ledge 344A. Third planar end 345A terminates at top end 302A. First side 308 also includes base 360A arranged proximate to bottom end 302B. Protrusion 362A extends from base 360A and is further arranged to extend along base 360A from first end 303 to second end 304.

[0116] Second side 309 is defined by tapered portion 340B which terminates at first planar end 341B. First planar end 341B terminates at first ledge 342B. Second planar end 343B extends from first ledge 342B. Second planar end 343B terminates at second ledge 344B. Third planar end 345B extends from second ledge 344B. Third planar end 345B terminates at top end 302A. Second side 309 also includes base 360B arranged proximate to bottom end 302B. Protrusion 362B extends from base 360B and is further arranged to extend along base 360B from first end 303 to second end 304.

[0117] Channel 350 is disposed within first end 303 of corbel 300, having an open portion on first end 303. Channel 350 has two ends, the first end is disposed within recess 330A and the second end is disposed within tapered portion 340A, first planar end 341A, and first ledge 342A of first side 308. It should be appreciated that channel 350 may alternatively be arranged to have its second end disposed within second side 309 (i.e., within tapered portion 340B, first planar end 341B, and first ledge 342B). The open portion of channel 350 is arranged to be closed and/or sealed by second end 304 of an adjacent corbel 300 that is abutting first end 303 of corbel 300 having channel 350 therein. Alternatively, channel 350 may be alternatively arranged within corbel 300 in a substantially similar arrangement of channel 250 of corbel 200 illustrated in FIG. 6E.

[0118] It should be noted that protrusions 362A and 362B are operatively arranged to engage recesses in foundation 26. The engagement between protrusions 362A and 362B and the recesses in foundation 26 help with alignment and securement of corbel 300 during installation. Protrusions 362A and 362B forms a portion of tier T4 and engages tier T4 of foundation 26, as shown in FIG. 7. The arrangement of protrusions 362A and 362B, extending from bases 360A and 360B and engaged with foundation 26, provides for added securement of corbel 300 to foundation 26. Protrusions 362A and 362B increase the surface area with which corbel 300 can be secured to foundation 26 and further eliminate shifting of corbel 300 in directions D5 and D6.

[0119] It should be appreciated that an important aspect of corbel 300 is that its configuration provides the intermediate tiers between foundation 26 and floor 28, as well as a portion of tier T4 and possible tier T3 (as shown in FIG. 7). Specifically, corbel 300 provides tiers T4-6 in a single, integrally formed block. By providing a portion of tier T4, namely, foundation 26, a stronger and easier connection between corbel 300 and foundation 26 is formed.

[0120] Tier T7 is arranged to be supported by first ledge 342A (and/or first ledge 342B). The respective block of tier T7 is specifically arranged to be placed on first ledge 342A (and/or first ledge 342B) and abut second planar end 343A (and/or second planar end 343B), where second planar end 343A prevents the block of tier T7 from moving in direction D5 or D6.

[0121] Floor 28, comprising tier T8 and/or T9, is arranged to be supported by second ledge 344A (and/or second ledge 344B). The respective block, or blocks, of floor 28, are specifically arranged to be placed on second ledge 344A (and/or second ledge 344B) and abut third planar end 345A (and/or third planar end 345B), where third planar end 345A prevents the respective block, or blocks of floor 28 (tier T8 and/or T9) from moving in direction D5 or D6.

[0122] The arrangement of corbel 300 provides for engagement and support of various tiers of

[0123] floor 28 at different locations. This allows not only for increased support strength of floor 28, but also for easy repair of floor 28. For example, due to loading and unloading of coal/coke from ovens 34, over time floor 28 exhibits damage thereto. Typically, this damage occurs on the top layer of floor 28, namely, tier T9. The design of corbel 300 (i.e., the support of two or more layers of floor 28) allows for tier T9 to be easily removed and a new tier T9 placed, without having to remove any other tier of floor 28. Since the entirety of floor 28 does not need to be replaced, battery 10 down time and labor cost is saved.

[0124] Since corbel 300 generally comprises tiers T5 and T6 and portions of tiers T4 and T7 through T9, existing seams created by the plurality of blocks that once comprised these tiers are eliminated-eliminating potential leak points of gas, and/or heat.

[0125] The following description should be taken in view of all of the aforementioned figures. Tapered portions 120A and 120B (of corbel 100), 240A and 240B (of corbel 200), and 340A and 340B (or corbel 300) form a V-shape when combined with a tapered portion of an adjacent corbel. This V-shape configuration funnels air, traveling in direction D1, into channels 40 (of coke oven 10 having corbel 100 therein), 250 (of corbel 200), and 350 (of corbel 300).

[0126] In a preferred embodiment, the horizontal through-bore of the respective gunblock

[0127] sections of corbels 100, 200, 300 will have a first end and a second end, defined by a respective opening. One of the openings will have a recessed portion and the opposite opening will have a lip portion, or protruding portion, extending therefrom. The recess and lip are arranged to facilitate easy connection between two corbels, whereas the lip portion of the horizontal through-bore is arranged to be seated within the recessed portion of a horizontal through-bore of an adjacently placed corbel, as discussed supra. This arrangement increases the sealed nature of fluidly-connected horizontal through-bores of respective gunblock sections.

Coke Oven Battery (Underfire)

[0128] Referring now to the figures, the following description should be taken in view of FIGS. 10 and 14, as these illustrations generally illustrate a representative cross-sectional view of a portion of an under-fire style coke oven battery in accordance with the technology of the present invention.

[0129] FIG. 10 is a partial cross-sectional view of coke oven battery 10 illustrating an embodiment of corbel 400 for an under-fire style coke oven. Coke oven battery 10 generally comprises regenerator 20, pier 22, slab 46, basement 50, gas line 52, corbel 400, floor 28, heating wall 30, flue 32, and oven 34. It should be noted that coke oven battery 10 shares many of the same components as coke oven battery 10, however, the main difference being that gas is introduced into heating walls 30 from underneath the entire structure, e.g., within basement 50, unlike coke oven 10 where gas is fed into the gunblock structure of the corresponding corbel (e.g., corbels 100, 200, 300). In other words, coke oven 10 is generally depicted as a gun-fire coke oven. Regenerator 20 houses pier 22, which is supported by slab 46. Slab 46 provides a base

[0130] for entire structure of battery 10 arranged above. Corbel 400 supports floor 28 of oven 34 and also supports heating wall 30. Corbel 400 includes diagonal channel 422, which directs exhaust gases from flue 32 in heating wall 30 downwards towards regenerator region 24. The configuration of pier 22 and slab 46 allows communication between regenerator region 24 and through-bore 48 in slab 46 via a pair of vertical through-bores 44 in pier 22. Basement 50 houses gas line 52, which provides fuel for combustion in heating wall 30.

[0131] More specifically, corbel 400 includes a main body with top face 402 and bottom face 403. Extending from respective sides are upper and lower side extensions that form ledges, 415, 416, 417, 418, which support the bricks or blocks that form floor 28 of oven 34. Distal extension 413 extends from bottom face 403 of corbel 400. Two through-bores, first through-bore 425 and second through-bore 426, run vertically through corbel 400. Diagonal channel 422 is disposed within corbel 400 and fluidly connects flue 32 with regenerator region 24, with one end opening into top face 402 and the other end opening into one of the respective sides of corbel 400.

[0132] In some embodiments, corbel 400 may further include base block 500, which is supported by pier 22. Corbel 400, specifically distal extension 413 is arranged to be seated within notch 508 of base block. Base block 500 includes two through-bores, first through-bore 512 and second through-bore 513 which extend through notch 508 and bottom face 503. Through-bores 512 and 513 fluidly connect through-bores 425 and 426 of corbel 400 with the pair of through-bores 44 of pier 22.

[0133] FIG. 14 is also a partial cross-sectional view of coke oven battery 10 illustrating an embodiment of corbel 600 for an under-fire style coke oven. Coke oven battery 10 generally comprises regenerator 20, pier 22, slab 46, basement 50, gas line 52, corbel 400, floor 28, heating wall 30, flue 32, and oven 34.

[0134] Pier 22 is arranged within regenerator 20. Slab 46 is arranged beneath pier 22. Slab 46 is in fluid communication with basement 50 via through-bore 48. Gas line 52 is arranged within basement 50. Corbel 600 rests directly on pier 22. Floor 28, making up a plurality of blocks or bricks, is stacked on corbel 600, specifically on ledges 614-617. Heating wall 30 is stacked on the topmost portion of corbel 600. Flue 32 is arranged within heating wall 30. Diagonal channel 621 is in fluid communication with heating wall 32 and regenerator region 24, allowing exhaust gases flow from flue 32 through diagonal channel 621 and into the regenerator region.

[0135] Corbel 600, shown in FIG. 14, differs from corbel 400, shown in FIG. 10, in that corbel 600 does not include distal extension 413 and rests directly on pier 22, whereas corbel 400 includes distal extension 413 and a pair of tongues (See FIGS. 11A-11D), which are configured to mate with a respective pair of grooves (See FIG. 13) in base block 500, which rests on pier 22.

Corbel: Fourth Embodiment

[0136] The follow description pertains to the fourth embodiment of the present invention, corbel 400 and base block 500, as shown in coke oven battery 10 in FIG. 10 and should be taken in view of FIGS. 10-13.

[0137] FIGS. 11A, 11B, 11C and 11D are isometric views of corbel 400. FIGS. 11A and 11B are generally shown from the front and the second side and FIGS. 11C and 11D are generally shown from the rear and the first side.

[0138] Corbel 400 is a monolithic block comprising body 401. Body 401 includes multiple faces and extensions. The faces are top face 402, bottom face 403, front face 404, rear face 405, first side face 406, and second side face 407. Extending outwards from the side faces are first side extension 408, second side extension 410, third side extension 411, and fourth side extension 412. First side extension 408 and second side extension 410, located towards the upper portion of body 401, form first ledge 415 and second ledge 416, respectively. Third side extension 411 and fourth side extension 412, located below the upper side extensions, form third ledge 417 and fourth ledge 418, respectively. Distal extension 413 projects downwards from bottom face 403. Vertical extension 414 projects upwards from top face 402, creating first recess 420 and second recess 421.

[0139] Diagonal channel 422, which plays a crucial role in directing exhaust gases, extends diagonally along front face 404 from top face 402 to one of the lower side extensions, e.g., fourth side extension 412. Top end 423 (i.e., a top opening) is arranged within top face 402 and distal end 424 (i.e., a distal opening) is arranged within one or more of fourth side extension 412 or bottom face 403.

[0140] First and third side extensions 408, 411 which form first and third ledges 415, 417, are shown in FIGS. 11C and 11D. Second and fourth side extensions 410, 412 which form second and fourth ledges 416, 418, are shown in FIGS. 11A and 11B.

[0141] Two vertical through-bores, first through-bore 425 and second through-bore 426, penetrate body 401. First through-bore 425 has first outlet 428 located within first recess 420 and first inlet 427 located within distal extension 413. Similarly, second through-bore 426 has second outlet 431 located within second recess 421 and second inlet 430 located within distal extension 413. First tongue 443 and second tongue 444 extend downwards from bottom face 403 near distal extension 413 and on opposite sides thereof. These tongues are designed to mate with corresponding features on a base block (as depicted in FIG. 10), which rests atop pier 22.

[0142] As shown in FIGS. 11C and 11D, first and third side extensions 408, 411 form first and third ledges 415, 417. Specifically, first ledge 415 is formed by first side face 406 and top surface 432 of first side extension 408, and second ledge 417 is formed by external face 434 of first side extension 408 and top surface 436 of second side extension 411. Top surface 432 and top surface 436 are respective platforms of ledges 415 and 417 which allow one or more floor blocks to be stacked thereon (See FIG. 10). First side face 406 and external face 434 are respective barriers of ledges 415 and 417 which prevent one or more floor blocks stacked on ledges from being horizontally displaced in a direction towards the internal through-bores.

[0143] As shown in FIGS. 11A and 11B, second and fourth side extensions 410, 412 form second and fourth ledges 416, 418. Specifically, second ledge 416 is formed by second side face 407 and top surface 433 of second side extension 410, and second ledge 418 is formed by external face 435 of second side extension 410 and top surface 437 of fourth side extension 412. Top surface 433 and top surface 437 are respective platforms of ledges 416 and 418 which allow one or more floor blocks to be stacked thereon (See FIG. 10). Second side face 407 and external face 435 are respective barriers of ledges 416 and 418 which prevent one or more floor blocks stacked on ledges from being horizontally displaced in a direction towards the internal through-bores.

[0144] FIG. 12 is a skeleton view of corbel 400. Distal extension 413 extends downwards from bottom face 403 of body 401. Vertical extension 414 extends upwards from top face 402. First through-bore 425 extends through body 401 from top face 402 to distal extension 413. First inlet 427 of first through-bore 425 is positioned within distal extension 413. First outlet 428 of first through-bore 425 is positioned within first recess 420 formed by vertical extension 414. Second through-bore 426 extends through body 401 from top face 402 to distal extension 413. Second through-bore 426 has second inlet 430 located within distal extension 413. Second outlet 431 second through-bore 426 is located within second recess 421 formed by vertical extension 414. It should be noted that one or more of the inlets or outlets of each of through-bores 425 and 426 may be countersunk or alternative, may protrude away from the respective surface or face they are disposed within.

[0145] FIG. 13 is a skeleton view of base block 500 which is designed to accept corbel 400 therein. Base block 500 may be considered the base portion of corbel 400. Base block 500 comprises body 501. Body 501 has top face 502, bottom face 503, front face 504, rear face 505, first side face 506, and second side face 507. First groove 510 and second groove 511 are disposed within top face 502, proximate side faces 506 and 507. Notch 508 is disposed between first groove 510 and second groove 511 within top face 502 and extends through front 504 and rear face 505. First through-bore 512 and second through-bore 513 are disposed within body and extend through notch 508 and bottom face 503. First inlet 514 of first through-bore 512 is disposed within bottom face 503, and first outlet 517 of first through-bore 512 is disposed within notch 508. Second inlet 515 of second through-bore 513 is disposed within bottom face 503, and second outlet 516 of second through-bore 513 is disposed within notch 508. Optionally, notch 518 may be disposed within one of the side faces and may become a portion of the distal end of the diagonal channel of corbel 400, that is, the distal end or distal opening of the diagonal channel may be arranged within one or more of the bottom face of corbel 400, one of the side faces of corbel 400, or one of the side faces of base block 500.

[0146] In accordance with the technology of the present disclosure and the tongue and groove mating components, one having skill in the art would appreciate that bottom face 503 of base block 500 could have a pair of tongues, similar to those of corbel 400, disposed thereon, which tongues of base block 500 would engage a pair of respective grooves disposed within pier 22.

[0147] In reference to FIGS. 10-13, corbel 400 and base block 500 are designed to interact in a precise manner, creating a stable and efficient structure within the coke oven battery, while making installation simpler. As shown in FIG. 10, corbel 400 is stacked on top of base block 500. The distal extension 413 of corbel 400 fits within notch 508 of base block 500. Furthermore, the first tongue 443 and second tongue 444 on corbel 400 mate with the first groove 510 and second groove 511, respectively, on base block 500. This tongue-and-groove configuration ensures proper alignment and a secure connection between the two components, preventing shifting or displacement during operation, while also creating sharp angles across the respective joints therebetween, which significantly reduces the potential for gas leakage that may occur across straight joints. Inlets 427 and 430 of through-bores 425 and 426 in corbel 400 align with outlets 515 and 517 in base block 500, and inlets 514 and 516 in base block 500 align with the vertical through-bores 44 in pier 22. This creates a continuous passage for fluids to flow from the basement 50 up through pier 22, base block 500, corbel 400 and into flue 32.

[0148] The monolithic design of corbel 400 and base block 500 simplifies the construction of the coke oven battery and enhances its structural integrity. As illustrated in FIG. 10, corbel 400 alone encompasses tiers T3 through T6, and portions of tiers T7, T8, and T9. Base block 500 encompasses tiers T1 and T2. Traditionally, each of these tiers would have been constructed using multiple individual blocks or bricks. By integrating these tiers into single, monolithic components, the number of individual pieces and, consequently, the number of joints or seams is significantly reduced. This minimizes potential leak points for gases and heat, improves structural stability, streamlines the construction process, and reduces downtime for repairs.

Corbel: Fifth Embodiment

[0149] The follow description pertains to the fifth embodiment of the present invention, corbel 600, as shown in coke oven battery 10 in FIG. 14 and should be taken in view of FIGS. 14-16.

[0150] FIGS. 15A, 15B, 15C and 15D are isometric views of corbel 600. FIGS. 15A and 15B are generally shown from the front and the second side and FIGS. 15C and 15D are generally shown from the rear and the first side.

[0151] Corbel 600 is a monolithic component, meaning it is formed as a single, integrated piece, which contributes to its strength and stability and replaces more tiers of blocks or bricks than corbel 400, described supra. It comprises body 601, which forms the core of the structure.

[0152] Body 601 is characterized by multiple faces: top face 602, bottom face 603, front face 604, rear face 605, first side face 606, and second side face 607.

[0153] Extending outwards from the side faces are four side extensions: first side extension 608, second side extension 610, third side extension 611, and fourth side extension 612, where side extensions 608 and 610 are considered upper side extensions and side extensions 611 and 612 are considered lower side extensions. These side extensions are tiered, creating ledges that support other components and enhance the overall structural integrity. First side extension 608 and second side extension 610 form the upper tier of extensions, creating first ledge 614 and second ledge 615, respectively. Below these, third side extension 612 and fourth side extension 611 form the lower tier of extensions and create third ledge 616 and fourth ledge 617, respectively. This tiered arrangement of ledges provides multiple levels of support and allows for a more secure and stable stacking of blocks or bricks thereon, while reducing the number of joints.

[0154] Rising from top face 602 is vertical extension 613. This extension incorporates two recesses: first recess 618 and second recess 620. These recesses are strategically positioned to house the outlet openings of the through-bores that run vertically through the corbel's body. Across front face 604, from top end 622 (i.e., a top opening) of top face 602 to distal end 623 (i.e., a distal opening), extends diagonal channel 621. This channel plays a crucial role in directing the flow of exhaust gases within the coke oven battery.

[0155] Two vertical through-bores, first through-bore 624 and second through-bore 625, traverse the body of the corbel. First through-bore 624 begins with first inlet 626 located on bottom face 603 and terminates with first outlet 627 situated within first recess 618. Second through-bore 625 begins with second inlet 628, also located on bottom face 603, and terminates with second outlet 630 situated within second recess 620.

[0156] Several features on the faces and extensions of corbel 600 contribute to its ability to mate securely with other components. Tapered face 640 slopes downwards from the external face 638 of third side extension 612 towards bottom face 603. Similarly, tapered face 641 slopes downwards from the external face of fourth side extension 611 towards bottom face 603. These tapered faces essentially form a portion of a ceiling of the regenerator regions arranged below.

[0157] As shown in FIGS. 15C and 15D, first and third side extensions 608, 611 form first and third ledges 614, 616. Specifically, first ledge 614 is formed by first side face 606 and top surface 631 of first side extension 608, and second ledge 616 is formed by external face 633 of first side extension 608 and top surface 635 of second side extension 611. Top surface 631 and top surface 635 are respective platforms of ledges 614 and 616 which allow one or more floor blocks to be stacked thereon (See FIG. 14). First side face 606 and external face 633 are respective barriers of ledges 614 and 616 which prevent one or more floor blocks stacked on ledges from being horizontally displaced in a direction towards the internal through-bores.

[0158] As shown in FIGS. 15A and 15B, second and fourth side extensions 610, 612 form second and fourth ledges 615, 617. Specifically, second ledge 615 is formed by second side face 607 and top surface 632 of second side extension 610, and second ledge 617 is formed by external face 634 of second side extension 610 and top surface 636 of fourth side extension 612. Top surface 632 and top surface 636 are respective platforms of ledges 615 and 617 which allow one or more floor blocks to be stacked thereon (See FIG. 14). Second side face 607 and external face 634 are respective barriers of ledges 615 and 617 which prevent one or more floor blocks stacked on ledges from being horizontally displaced in a direction towards the internal through-bores.

[0159] FIG. 16 is a skeleton view of corbel 600. Vertical extension 613 extends upwards from top face 602. First through-bore 624 extends through body 601 from top face 602 to bottom face 603. First inlet 626 of first through-bore 624 is positioned within bottom face 603. First outlet 627 of first through-bore 624 is positioned within first recess 618 formed by vertical extension 613. Second through-bore 625 extends through body 601 from top face 602 to bottom face 603. Second through-bore 625 has second inlet 628 located within bottom face 603. Second outlet 630 of second through-bore 625 is located within second recess 620 formed by vertical extension 613. It should be noted that one or more of the inlets or outlets of each of through-bores 624 and 625 may be countersunk or alternative, may protrude away from the respective surface or face they are disposed within.

[0160] The monolithic design of corbel 600 significantly simplifies the construction of the coke oven battery compared to traditional methods that rely on a multitude of individual blocks or bricks. As depicted in FIG. 14, corbel 600 consolidates tiers T3 through T6, and portions of tiers T7, T8 and T9 into a single, integrated structure. In conventional coke oven designs, each of these tiers would be built using numerous smaller blocks, resulting in a large number of joints or seams. The monolithic construction of corbel 600 eliminates these seams, minimizing potential leak points for gases and heat, enhancing structural stability, and streamlining the assembly process. This reduction in the number of components also simplifies repairs and reduces downtime.

[0161] Compared to corbel 400 (FIGS. 10-13), corbel 600 shares many similarities but also exhibits key differences. Both corbels are monolithic and incorporate multiple tiers, reducing the need for numerous smaller blocks. Both also feature through-bores for fluid flow, diagonal channels for exhaust gas direction, and ledges to support the oven floor. However, corbel 400 includes a distal extension 413 and mating tongues 443 and 444 that are designed to interlock with a separate base block 500, which rests atop pier 22. Corbel 600, in contrast, lacks these features and rests directly on pier 22, eliminating the need for a separate base block and further reducing the overall component count. This design variation offers flexibility in construction and allows for adaptation to different coke oven configurations and repair scenarios. However, one having skill in the art should appreciate that bottom face 603 of corbel 600 could have a pair of mating tongues disposed thereon, which tongues would interact and mate with a pair of respective grooves positioned within the respective pier that corbel 600 is stacked on.

Corbel: Sixth Embodiment

[0162] Adverting now to FIGS. 17A through 18 which illustrate a sixth embodiment of a corbel of the present invention. In the exemplary illustrations, corbel 600 is shown having front face protrusion 642 extending from front face 604 and also having rear face recess 643 disposed within rear face 605. As shown in FIG. 18, rear face recess 643 of corbel 600 (left) is designed to accept at least a portion of front face protrusion 642 of corbel 600 (right) therein, creating a mating connection between the two adjacently arranged corbels, i.e., similar to a tongue and groove interaction. As such, corbel 600 includes at least one mating protrusion (e.g., front face mating protrusion 642) extending from one of its front or rear faces (e.g., front face 604) and corbel 600 also includes at least one mating recess (e.g., rear face recess 643) disposed within one of its front or rear faces (e.g., rear face 605). The mating protrusion is arranged to have a complimentary shape with its respective mating recess. In other words, the one or more mating recesses will have a configuration that allows the one or more mating protrusions to be at least partially seated therein. In accordance with the technology of the present disclosure, protrusion 642 and recess 643 are intended to exemplary, as various different sizes, shapes, and quantities may be employed, so long as a 1:1 ratio of recesses and protrusions are maintained.

[0163] Although various alternative mating protrusions and recesses are contemplated, larger-sized complimentary mating protrusions and recesses, e.g., protrusion 642 and recess 643, are preferred as they surface area creates a large break in what otherwise would be straight joint between two adjacent corbels, e.g., front face 604 of corbel 600 abutting rear face 605 of corbel 600. This break improves the seal between the joint created by abutting the front and rear faces, further reducing potential leak and/or failure points.

[0164] Further alternative mating protrusions and recesses are detailed infra and in view of the seventh embodiment.

[0165] It should be noted that the aforementioned mating recesses and mating protrusions, in any of their contemplated alternative configurations or quantities, may be applied to any of the corbel embodiments described in this disclosure.

Corbel: Seventh Embodiment

[0166] In reference to FIGS. 19A through 23B, corbel 700 is an exemplary embodiment of a monolithic, dual air-flue, coke oven corbel configuration, which may be employed in one or more of a gunfire coke oven or an underfire coke oven.

[0167] Corbel 700 includes body 701 with front face sections 704a, 704b and 704c, where the front face sections generally define a front face of body 701, and rear face sections 705a, 705b, and 705c, where the rear face sections generally define a rear face of body 701. Body 701 also includes top face 702, bottom face sections 703a and 703b, first side face 706, and second side face 707.

[0168] First side extension 708 extends from first side face 706, forming first ledge 714. Second side extension 710 extends from second side face 707, forming second ledge 715. Third side extension 711 extends from first side face 706, forming third ledge 716. Fourth side extension 712 extends from second side face 707, forming fourth ledge 717. Vertical extension 713 extends from top face 702 and forms first recess 718 and second recess 720. First diagonal channel 721 extends from top end 723 to distal end 724, and second diagonal channel 722 extends from top end 725 to distal end 726. Through-bore 727 includes inlet 728 and outlet 730 (shown in FIG. 20). Top faces 731, 732, 735 and 736 are present. External faces 733, 734, 737, and 738 are also shown, along with tapered faces 740 and 741. First rear face protrusion 742 and second rear face protrusion 743 are positioned on the rear face and extend therefrom. Distal notch 744 and proximal bottom face section 745 are also visible. First distal mating protrusion 746 and second distal mating protrusion 747 extend from bottom face sections 703a and 703b, respectively. First proximal mating groove 748 and second proximal mating groove 750 are arranged within vertical extension 713.

[0169] Several features on the faces and extensions of corbel 700 contribute to its ability to mate securely with other components. Tapered face 740 slopes downwards from the external face 637 of third side extension 711 towards bottom face section 703a. Similarly, tapered face 741 slopes downwards from the external face of fourth side extension 712 towards bottom face section 703b. These tapered faces essentially form a portion of a ceiling of the regenerator regions arranged below.

[0170] First and third side extensions 708, 711 form first and third ledges 714, 716. Specifically, first ledge 714 is formed by first side face 706 and top surface 731 of first side extension 708, and second ledge 716 is formed by external face 733 of first side extension 708 and top surface 735 of third side extension 711. Top surface 731 and top surface 735 are respective platforms of ledges 714 and 716 which allow one or more floor blocks to be stacked thereon (similar to that shown in FIG. 14). First side face 706 and external face 733 are respective barriers of ledges 714 and 716 which prevent one or more floor blocks stacked on ledges from being horizontally displaced in a direction towards the internal through-bores.

[0171] Second and fourth side extensions 710, 712 form second and fourth ledges 715, 717. Specifically, second ledge 715 is formed by second side face 707 and top surface 732 of second side extension 710, and second ledge 717 is formed by external face 734 of second side extension 710 and top surface 736 of fourth side extension 712. Top surface 732 and top surface 736 are respective platforms of ledges 715 and 717 which allow one or more floor blocks to be stacked thereon (similar to that shown in FIG. 14). Second side face 707 and external face 734 are respective barriers of ledges 715 and 717 which prevent one or more floor blocks stacked on ledges from being horizontally displaced in a direction towards the internal through-bores.

[0172] In reference to FIGS. 19A and 19B, front face sections 704a, 704b, and 704c function as mating protrusions designed to align with and at least partially insert into corresponding rear face sections 705a, 705b, and 705c of an adjacent corbel 700, e.g., FIGS. 21A, 21B. Specifically, front face section 704a is adapted to be at least partially inserted into rear face section 705a of another corbel 700, and so on. This arrangement is similar to a tongue and groove connection, where the front face sections 704a-c act as tongues fitting into the grooves formed by the rear face sections 705a-c.

[0173] The benefits of this configuration are multi-fold. First, it ensures precise alignment and interlocking between adjacent corbels 700, e.g., FIGS. 21A, 21B, contributing to the overall stability and structural integrity of the coke oven battery. Secondly, it creates a more effective seal between the corbels, minimizing gas or air leakage and improving thermal efficiency. The tongue and groove-like connection also provides resistance to lateral displacement, preventing the corbels from shifting or separating under the extreme thermal and mechanical stresses experienced during coke production. This interlocking design contributes to a more robust and durable structure, extending the lifespan of the coke oven battery and reducing maintenance requirements.

[0174] In FIGS. 19A and 19B, diagonal channels 721 and 722 function as mating recesses that receive first rear face protrusion 742 and second rear face protrusion 743, respectively, of an adjacent corbel 700, e.g., FIGS. 21A, 21B. This interlocking arrangement effectively closes the open portions of diagonal channels 721 and 722, which are formed between front face sections 704a, 704b, and 704c, thereby leaves the proximal and distal ends of both diagonal channels 721 and 722 as the sole outlets/inlets to the channels (e.g., air flues).

[0175] This configuration, similar to a tongue and groove connection, provides several benefits. The channels and protrusions interlock, creating a more complete and sealed air flue. This sealing action minimizes air leakage and ensures that the flow of gases is directed efficiently towards the intended destination within the coke oven. The interlocking nature of the connection further enhances the structural stability of the corbel assembly, preventing lateral displacement and maintaining the integrity of the air flue system even under high temperatures and mechanical stress.

[0176] FIG. 20 shows a front view of corbel 700. The view illustrates the relative positions of front face sections 704a, 704b and 704c relative to rear face sections 705a, 705b and 705c. A portion of first diagonal channel 721 is visible, as is second diagonal channel 722. Through-bore 727 and outlet 730 on the top face are also visible. First rear face protrusion 742 and second rear face protrusion 743 are also shown.

[0177] FIGS. 21A, 21B, and 21C collectively illustrate the mating arrangement between two adjacent corbels, corbel 700a and corbel 700b, illustrating the tongue and groove or interlocking capabilities between corresponding components.

[0178] FIG. 21A, a top-down view, presents the general alignment and relative positions of corbel 700a and corbel 700b. From this perspective, the overall layout and interlocking nature of the corbels become apparent. The detailed interaction between the two corbels is further explored in the subsequent figures.

[0179] FIG. 21B focuses on the interface between corbel 700a and corbel 700b, revealing the specific engagement mechanisms. The front face sections, designated as 704a, 704b, and 704c, are designed to mate with corresponding rear face sections 705a, 705b, and 705c, respectively. This interlocking configuration ensures a secure and stable connection between the adjacent corbels. Also prominent in this view are first rear face protrusion 742 and second rear face protrusion 743, along with the diagonal channels 721 and 722, which play a crucial role in gas flow management within the coke oven battery. As described supra, first rear face protrusion 742 and second rear face protrusion 743 close the open portion of diagonal channels 721 and 722 that is formed between 704a, 704b, and 704c, however, it should be appreciated that first rear face protrusion 742 and second rear face protrusion 743 are only partially inserted into diagonal channels 721 and 722, providing a fluid connection between the respective proximal and distal ends, or openings, of each of the diagonal channels.

[0180] FIG. 21C further clarifies the mating process by illustrating the directional alignment of the adjacent corbels. The arrows indicate the direction of insertion, emphasizing how front face sections 704a, 704b, and 704c are inserted into rear face sections 705a, 705b, and 705c, causing diagonal channels 721 and 722 to interlock with protrusions 742 and 743. This view underscores the precision and deliberate design of the interlocking mechanism, highlighting its contribution to the overall structural integrity and performance of the coke oven.

[0181] As stated supra, corbel 700 is a monolithic, dual air-flue, coke oven corbel configuration, which may be employed in one or more of a gunfire coke oven, e.g., FIG. 23A, or an underfire coke oven, e.g., FIG. 23B.

[0182] FIG. 22 illustrates corbel 700, an embodiment of corbel 100, and an alternative embodiment of base block 500, e.g., base block 800. As generally depicted, corbel 700 may connect with either corbel 100 or base block 800 to form a corbel unit, e.g., gunfire corbel unit GFCU or underfire corbel unit UFCU, illustrated in FIGS. 23A and 23B, respectively.

[0183] Corbel 100, as shown in FIGS. 22 and 23A, is substantially identical to corbel 100 shown in FIGS. 3A through 3D, however, vertical through-bore 110 has been aligned to fluidly connect with inlet 728 of through-bore 727 of corbel 700. In some embodiments, vertical through-bore 110 may have lip 110a extending from top end 102a, where lip 110a is adapted to be at least partially seated within a corresponding recess (or counter-sink) of inlet 728. Accordingly, grooves 126a and 126b of shoulders 122a and 122b are arranged to at least partially accept distal mating protrusions 746 and 748 therein. Further, gunblock section 101 of corbel 100 is arranged to be seated within notch 744 of corbel 700. Once corbel 100 is connected to corbel 700, gunfire corbel unit GFCU is formed (shown in FIG. 23A).

[0184] Base block 800, as shown in FIGS. 22 and 23B, is designed to accept corbel 700 thereon and therein. Base block 800 may be considered the base portion of corbel 700. Base block 800 comprises body 801. Body 801 has top face 802, bottom face 803, front face 804, rear face 805, first side face 806, second side face 807, first shoulder face 808, second shoulder face 810, third side face 811, and fourth side face 812. First groove 813 and second groove 814 are disposed within first shoulder face 808 and second shoulder face 810, respectively. Base block 800 comprises a pair of shoulders, a first shoulder defined by first shoulder face 808 and third side face 811, and a second shoulder defined by second shoulder face 810 and fourth side face 812. Each of the shoulders have a mating groove disposed therein, specifically, first groove 813 is disposed within first shoulder face 808 and second groove 814 is disposed within second shoulder face 810. Through-bore 815 is disposed within body 801 between top face 802 and bottom face 803 and has a respective inlet and outlet, inlet 816 arranged with bottom face 803 and inlet 817 disposed within top face 802, where outlet 817 has lip 818 circumscribed therearound. Optionally, there may be one or more notches (similar to notch 518 of base block 500) may be disposed within one of the side faces and may become a portion of the distal end of the diagonal channel of corbel 700, that is, the distal end or distal opening of the diagonal channel may be arranged within one or more of the bottom face of corbel 700, one of the side faces of corbel 700, or one of the side faces of base block 800.

[0185] Through-bore 815 of base block 800 is designed to fluidly connect with inlet 728 of through-bore 727 of corbel 700, specifically, lip 818 of outlet 817 is arranged to engage with a corresponding and respective recess of inlet 728 of through-bore 727. Accordingly, grooves 813 and 814 of the first and second shoulders, formed by first shoulder face 808 and third side face 811, and formed by second shoulder face 810 and fourth side face 812, are arranged to at least partially accept distal mating protrusions 746 and 748 therein. Once base block 800 is connected to corbel 700, underfire corbel unit UFCU (shown in FIG. 23B).

[0186] One having skill in the art will appreciate the double air flue configuration of corbel 700 (e.g., channels 721 and 722) may be adapted to any of the corbel embodiments, less corbel 100. Accordingly, corbel 700 could be alternatively configured with a single air flue configuration (e.g., one of channels 721 and 722).

[0187] While the invention has been described with reference to multiple embodiments, it will be understood that various features, elements, and configurations of the described embodiments may be combined, substituted or rearranged without departing from the scope of the invention. The embodiments are presented for illustrative purposes, and any feature described in connection with one embodiment may be used with any other embodiment, unless otherwise stated. Modifications and variations will be apparent to those skilled in the art in light of the foregoing description, thus various presently unforeseen or unanticipated alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
