(28) Coke Oven Battery

(29) 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.

(30) 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.

(31) 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.

(32) 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.

(33) 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 arrangement-less 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.

(34) 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.

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.

(37) 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.

(38) 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.

(39) 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.

(40) 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.

(41) 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 30 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.

(42) 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.

(43) 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.

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.

(52) 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.

(53) 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.

(54) 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 eliminatedthereby eliminating potential leak points of gas, and/or heat.

(55) 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.

(56) 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.

(57) 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.

(58) 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 20) second end 304.

(59) 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.

(60) 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.

(61) 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.

(62) 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.

(63) 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.

(64) The arrangement of corbel 300 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 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.

(65) 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 eliminatedeliminating potential leak points of gas, and/or heat.

(66) 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).

(67) In a preferred embodiment, the horizontal through-bore of the respective gunblock 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.

(68) It will be appreciated that various aspects of the invention and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. 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.
