Abstract
Description
- This application is based on and claims domestic priority benefits under 35 USC §119(e) from U.S. Provisional Patent Application Ser. No. 62/131,936 filed on Mar. 12, 2015, and may be deemed to be related to commonly owned copending U.S. patent application Ser. No. 14/947,320 filed on Nov. 20, 2015 and ______ filed concurrently herewith (Atty. Dkt. No. 6141-52), the entire content of each being expressly incorporated hereinto by reference.
- The embodiments disclosed herein relate generally to coke ovens, especially corbel structures associated with coke ovens. In preferred embodiments, the corbel structures disclosed herein are formed of an assembly of monolithic refractory blocks.
- Coke ovens traditionally comprise massive refractory brick structures in which there are batteries of adjacent parallel walls made up from a large variety of differently shaped refractory bricks. The bricks must be able to withstand high temperatures and strong mechanical loading. At the same time, the interior of the walls contains flue ducts, burners, flue gas control passages and the like. The detailed design of the oven is usually quite complicated in order to obtain the necessary heat distribution within the oven and gas flows through the walls.
- It follows from the above that coke ovens are relatively costly structures and any downtime for servicing and repairs can represent a significant economic loss for an operator.
- Further, the production of ceramic bricks from which the walls are made is relatively costly and there is accordingly a need to generally reduce the number of different types of bricks which are used in a wall. It is undesirable, however, to have a design concept which utilizes relatively large ceramic bricks in the construction. Excessively large bricks cannot be handled without the use of specialized mechanical lifting devices. Further, bricks having a dimension greater than 650 mm machine pressed to form a fused silica product are generally unavailable. Bricks greater than this size can be hand cast but these are much more expensive. Large bricks can be machine pressed from conventional silica, but conventional silica bricks would have a very serious disadvantage in that a wall made therefrom would need a heat-up time which is many times greater than that for fused silica bricks.
- U.S. Pat. Nos. 6,066,236, 8,266,853 and 8,640,635 (the entire content of each such patent being expressly incorporated hereinto be reference) have proposed that relatively large-sized monolithic refractory blocks may be assembled to form the corbel structures of coke ovens. In general, the assembly of such large-sized monolithic refractory blocks enables the coke ovens to be constructed and/or repaired with much less production down time.
- While such prior proposals for coke oven corbel structures are satisfactory for their intended purpose, continual improvements are sought. It is towards providing such improvements that the embodiments disclosed herein are directed.
- The coke oven corbel structures of the embodiments disclosed herein include an assembly of multiple stacked tiers of refractory blocks defining a plurality of substantially vertically oriented central flues. A first tier of refractory blocks in the assembly includes a series of lower cradle blocks defining respective lower semi-circular surfaces extending from one end to another end of the corbel structure. A second tier of the refractory blocks in the assembly includes a series of upper crown blocks defining respective upper semi-circular surfaces extending from one end to another end of the corbel structure.
- The second tier of refractory blocks is stacked on the first tier of refractory blocks so that the respective upper and lower semi-circular surfaces of the upper crown blocks and lower cradle blocks thereof oppose one another to thereby define a cylindrical channel between opposed ends of the corbel structure. At least one set of the upper crown blocks in the second tier of refractory blocks defines respective substantially vertical segments of the vertically oriented central flues of the corbel structure, a lower end of the substantially vertical segments terminating at the upper semi-circular surface to thereby be in fluid communication with the cylindrical channel of the corbel structure.
- According to certain embodiments, upper and lower end blocks may be provided at least at the one end of the corbel structure, wherein the upper and lower end blocks define opposed upper and lower rectangular U-shaped cradle surfaces. A transition gun block may thus be received within the U-shaped cradle surfaces of the upper and lower end blocks, in which case the transition gun block defines a gun block transition channel in fluid communication with the cylindrical channel defined by the upper and lower cradle blocks. The transition gun block may be in the form of a rectangular cuboid. Alternatively or additionally, the transition gun block may include upper and lower gun block sections defining opposed U-shaped surfaces to establish the gun block transition channel.
- Some embodiments of the corbel structure may include at least a second set of the upper crown blocks in the second tier of refractory blocks which defines respective diagonally oriented lateral flue segments of diagonally oriented lateral flues of the corbel structure. If present, the first and second sets of the upper crown blocks are positioned alternately adjacent to one another.
- A third tier of refractory blocks may be provided according to other embodiments, whereby the refractory blocks of the third tier are stacked on the second tier of refractory blocks. If present, the third tier of refractory blocks may comprise a series of inverted T-shaped flue blocks. The inverted T-shaped flue blocks may be provided with upper and lower ledge surfaces. Lower spacer blocks having respective ends supported by the lower edges of the inverted T-shaped flue blocks may thus be provided in the third tier of refractory blocks.
- Some embodiments will include at least one set of the inverted T-shaped blocks in the third tier of refractory blocks which defines respective substantially vertical segments of the vertically oriented central flues of the corbel structure. A lower end of the substantially vertical segments may thus be aligned with an upper end of the substantially vertical segments of upper cradle blocks so as to be in fluid communication therewith. The substantially vertical segments of the at least one series of inverted T-shaped blocks may be U-shaped. The U-shaped substantially vertical segments according to such embodiments would thereby have an open end closed by a vertical face of an adjacent one of the inverted T-shaped blocks.
- According to other embodiments, at least a second set of the inverted T-shaped blocks in the third tier of refractory blocks defines respective diagonally oriented lateral flue segments of diagonally oriented lateral flues of the corbel structure.
- Certain embodiments of the corbel structure will include a fourth tier of refractory blocks comprised of a series of elongate shoulder blocks positioned in an end-to-end manner on upper ledge surfaces of the inverted T-shaped blocks of the third tier. Upper spacer blocks may thus be positioned adjacent to the shoulder blocks and stacked on the lower spacer blocks.
- According to some embodiments, a series of split cylindrical gun blocks may be positioned in the cylindrical channel of the corbel structure. The cylindrical gun blocks may comprise upper and lower semi-cylindrical gun block sections. Some embodiments will include an aperture defined by at least some of the upper semi-cylindrical gun block sections which is in fluid communication with respective ones of the substantially vertical segments of the at least one set of the upper crown blocks.
- These and other aspects and advantages of the present invention will become more clear after careful consideration is given to the following detailed description of the preferred exemplary embodiments thereof.
- The disclosed embodiments of the present invention will be better and more completely understood by referring to the following detailed description of exemplary non-limiting illustrative embodiments in conjunction with the drawings of which:

More specifically, the central flue blocks 204 define a substantially vertically oriented rectangular segment of theflue 60, whereas the lateral flue crown blocks 202 define a diagonally oriented U-shaped channel which is closed by a vertical face of an adjacent one of theblocks 204. The central flue blocks 204 may include astatic gas nozzle 207 positioned in the segment of theflue 60 so as to control the flow of gas thereinto. - An
end block 206 is provided adjacent to a front face of the end-most one of the crown blocks 202. Theend block 206 is provided with an inverted rectangularU-shaped cradle surface 206 a to receive the uppergun block section 108 a of thetransition gun block 108. In addition, theend block 206 includes oppositely oriented mountingtongues 206 b so as to mate with corresponding channel surfaces 208 a associated with the wing blocks 208. In this regard, it will be observed that the lateral wing blocks 208 are each horizontally split to form upper and lowerwing block segments U-shaped channel 208 d which is closed by an opposed face of the upperwing block segment 208 b. - The
third tier 300 of blocks forming thecorbel structure 10 is depicted inFIG. 11 . As shown thethird tier 300 is comprised of an alternating series of inverted T-shaped lateral flue blocks 302 and inverted T-shaped central flue blocks 304, the former defining a section of the substantially vertically orientedflues 60 and the latter defining a section of the diagonally orientedflues 72. Lower spacer blocks 306 abut laterally against the side edges of theblocks second tier 200 of blocks. Theblocks lower ledges lower ledges - An inverted T-shaped
end block 306 is provided adjacent to a front face of the end-most one of theblocks 304. Theend block 306 defines a ledge 306 a which is coplanar with theledges blocks - The
fourth tier 400 of blocks forming thecorbel structure 10 is depicted inFIG. 12 . Thefourth tier 400 includes a series ofelongate shoulder blocks 402 positioned in an end-to-end manner on the upper ledge surfaces 302 b, 304 b of theblocks FIG. 11 ). A T-shapedend block 406 is positioned on the top surface of theend block 306 of thethird tier 300. Spacer blocks 406 are laid onto the spacer blocks 308 of thethird tier 300 in an abutting manner to the lateral surface of theblocks 402. - Another embodiment of a
corbel structure 500 is shown inFIGS. 13-17 . As is shown, thecorbel structure 500 includes threetiers courses flues 160 and lateral substantially diagonally orientedflues 172 which communicate with corresponding flues within the walls of the coke oven walls (not shown) to allow for the burning of air and gas therein and the transport of heated waste gas to and from the regenerator regions. - As is perhaps better shown in
FIG. 17 , thefirst tier 600 of thecorbel structure 500 is provided with an interconnected series of cradle blocks 602 that are somewhat similar to the cradle blocks 102 of thecorbel structure 10 as previously described. Each of the cradle blocks 602 defines a semi-cylindrical surface 604 extending longitudinally between the front and rear faces of each block. When a series of the cradle blocks 602 are aligned within one another, therefore, the semi-cylindrical surfaces 604 will therefore define a longitudinal U-shaped channel extending in a lengthwise direction of thecorbel structure 500. - A series of split cylindrical gun blocks 606 comprised of an upper semi-cylindrical gun block 606 a and a lower
semi-cylindrical gun block 606 b are positioned end-to-end relative to one another so that the lower semi-cylindrical gun blocks 606 b are received by a respective semi-cylindrical surface 604 of the cradle blocks 602. At least some of the upper semi-cylindrical gun blocks 606 a includeapertures 606 c which fluid-communicate with the substantially vertically orientedflues 160. Therefore, when assembled in an end-to-end manner, the split cylindrical gun blocks 606 will establish an elongatecylindrical passageway 607 which extends longitudinally through thecorbel structure 500. - The
second tier 700 is comprised of a series of an alternating series of lateral flue crown blocks 702 and central flue crown blocks 704, the former defining a section of the diagonally orientedflues 172, and the latter defining a section of the substantially vertically orientedflues 160. More specifically, the central flue crown blocks 704 define a substantially vertically oriented rectangular segment of theflue 160, whereas the lateral flue crown blocks 702 define a diagonally oriented U-shaped channel which is closed by a vertical face of an adjacent one of the blocks 204 (seeFIG. 17 ). The segments of theflue 160 defined by the crown blocks 704 are aligned withrespective apertures 606 c formed in the upper semi-cylindrical gun blocks 606 a. Non-apertured filler blocks 706 may be provided as needed (i.e., where it is not required to provide a section of theflues 160 and/or 172). - The crown blocks 702, 704 collectively define a
semi-cylindrical surface 708 which conformably mates with the semi-cylindrical gun blocks 606 a. The gun blocks 606 are thereby positionally captured between the crown blocks 702, 704 on the one hand and the cradle blocks 602 on the other hand. The crown blocks 704 may include astatic gas nozzle 807 positioned in the segment of theflue 160 so as to control the flow of gas thereinto. - The
third tier 800 is comprised of an alternating series of inverted T-shaped lateral flue cap blocks 802 and inverted T-shaped central flue cap blocks 804, the former defining a section of the substantially vertically orientedflues 160 and the latter defining a section of the diagonally orientedflues 172. Lower spacer blocks 806 abut laterally against the side edges of theblocks blocks second tier 700 of blocks. Theblocks lower ledges FIGS. 13-15 ) are thus supported by the lower spacer blocks 806 and have respective end portions which are received on thelower ledges flues - A series of
elongate shoulder blocks 812 is positioned in an end-to-end manner on the upper ledge surfaces 802 b, 804 b of theblocks FIG. 11 ). Spacer blocks 814 are laid onto the spacer blocks 808 in an abutting manner to the lateral surface of theblocks 812. - The various blocks as described above which comprise the
corbel structures - 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.
