DETAILED DESCRIPTION

[0021] Accompanying FIG. 1 shows an exemplary coke oven wall structure 10 in accordance with an embodiment of the present invention associated with a coke oven battery. In this regard, it will be understood that a conventional coke oven battery will include a number of spaced apart wall structures 10 defining therebetween regenerator regions provided with checker bricks associated with the individual coke ovens (not shown).

[0022] As shown in FIGS. 1 and 2, the wall structure 10 includes a number of substantially horizontally laid courses 10a each comprised of an end-to-end series of interconnected stacked blocks (a representative few of which are identified in FIG. 1 by reference numeral 12). Each of the individual blocks 12 are in turn constructed of a pair of interlocked opposing block components (a representative few of which are identified in FIG. 1 by reference numerals 20, 40). The stacked blocks 12 in the wall structure 10 define establish a number of substantially vertically oriented flue openings 14 therewithin so as to allow the passage therethrough of coke oven flue gases.

[0023] The orientation of the opposed interlocked block components 20, 40 in each course 10a is reversed as compared to the orientation of the block components 20, 40 in adjacent components. That is a block component 20 in one course 10a will be stacked between block components 40 in adjacent courses 10a, while conversely a block component 40 in one course 10a will be stacked between block components 20 in adjacent courses 10a. In the exemplary embodiment depicted, each course 10a of the wall structure 10 may terminate in a quoin block 60.

[0024] The blocks 12 and the opposed interlocked block components 20, 40 forming such blocks 12 are shown in greater detail in accompanying FIGS. 3-43. In this regard, each of the block components 20, 40 is generally an asymmetrical unitary T-shaped (hammerhead) block structure having an interior wall element 22, 42 which integrally (unitarily) formed at substantially a right angle (90) to a side wall element 24, 44, respectively, so as to extend inwardly relative to the wall structure 10 when stacked in a course 10a. Since the interior wall element 22, 42 is asymmetrically joined to the side wall element 24, 44 so as to offset from the transverse centerline thereof, the side wall elements 24, 44 will include longer and shorter wall side wall segments 24a, 24b and 44a, 44b, respectively.

[0025] The terminal ends of each of the interior wall elements 22, 42 includes an L-shaped notch 22a, 42a that in turn establishes a protruding finger element 22b, 42b. As noted in the drawing FIGS. 3-43, the L-shaped notches 22a, 42a and the thus established protruding finger elements 22b, 42b of each block 20, 40 are offset relative to one another along a vertical bisecting plane to allow the later to be received within the former when the blocks 20, 40 are positioned in opposing relationship to one another. Thus, when positioned in opposing relationship to one another, the protruding finger elements 22b, 44b will be received within an opposed L-shaped recess 22a, 44a of each block 20, 40 so as to collectively define a cross-sectional thickness dimension of the interior wall elements 22, 44, respectively.

[0026] As noted previously, the blocks 20, 40 are adapted to being interconnected in an end-to-end manner in each of the courses 10a of the wall structure 10 and stacked on top of one another. In order to provide sealing against escape of flue gases from the flue channels 14, each of the top and bottom faces of the side wall elements 24, 44 will include an elongate generally U-shaped recessed groove 24-1, 44-1 and an elongate generally U-shaped protruding tongue 24-2, 44-2, respectively. Opposed end faces of the side wall elements 24, 44 will similarly include an elongate generally U-shaped recessed groove 24-3, 44-3 and an elongate generally U-shaped protruding tongue 24-4, 44-4, respectively. It will be noted that the grooves 24-1, 24-3 and 44-1, 44-3 of the side wall elements 24, 44 will co-terminate with respective adjacent ends of the generally U-shaped tongues 24-2, 44-2 and 24-4, 44-4 at respective transverse edges of the side wall elements 24, 44 in a manner similar to that described in US 2016/0145494 (the entire content of which is expressly incorporated hereinto by reference).

[0027] The bottom face of the interior wall element 22 will include a pair of elongated alignment protrusions 22-1, 22-2 extending outwardly therefrom while the bottom face of the interior wall element 42 will include a single elongated alignment protrusion 42-1. As can be seen in, e.g., FIG. 7, the alignment protrusions are laterally separated from one another by substantially equal distances so that the protrusions 22-1 and 42-1 are oriented on respective lateral sides of the central protrusion 22-2. The top faces of the interior wall elements 22, 42 will each include an elongate recessed pocket 22-3, 42-3 to receive therein a respective one of the protrusions 42-1, 22-1, respectively, when correspondingly configured blocks 22, 42 are stacked on top of one another in an alternating manner as described previously. The top face of the interior wall element 22 of block 20 will also include a generally rectangularly shaped recessed pocket 22-4 oriented along the elongate axis of thereof which is adapted to receive therein the central alignment protrusion 22-2 of a correspondingly configured block 22 when stacked on top of one another in an alternating manner.

[0028] A representative example of the quoin block 60 that may be employed in the wall structure 10 is shown in FIGS. 44-48. As can be seen the quoin block 60 has a widthwise (lateral) dimension that is adapted to be received between the opposed side wall segments 24a, 44a and 24b, 44b, respectively. If needed, spacer blocks 62 (see FIG. 1) may be provided to as to provide a flush end surface to the wall 10. A laterally elongate central boss 60a protrudes outwardly from the quoin block 60. Since a number of quoin blocks 60 are to be stacked on top of one another, a pair of laterally separated elongate protrusions 60-1 are provided on the bottom surface of the blocks 60 so as to be received within correspondingly configured laterally separated elongate recessed pockets 60-2 formed on a top surface of the blocks 60.

[0029] It will be understood that the description provided herein is presently considered to be the most practical and preferred embodiments of the invention. Thus, the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope thereof.
