    Abstract: The present technology is generally directed to horizontal heat recovery and non-heat recovery coke ovens having monolith crowns. In some embodiments, an HHR coke oven includes a monolith crown that spans the width of the oven between opposing oven sidewalls. The monolith expands upon heating and contracts upon cooling as a single structure. In further embodiments, the crown comprises a thermally-volume-stable material. The crown may be an oven crown, an upcommer arch, a downcommer arch, a J-piece, a single sole flue arch or multiple sole flue arches, a downcommer cleanout, curvilinear corner sections, and/or combined portions of any of the above sections. In some embodiments, the crown is formed at least in part with a thermally-volume-stable material. In further embodiments, the crown is formed as a monolith (or several monolith segments) spanning between supports such as oven sidewalls. In various embodiments, the monolith and thermally-volume-stable features can be used in combination or alone. These designs can allow the oven to be turned down below traditionally feasible temperatures while maintaining the structural integrity of the crown.

    Abstract: The present technology is generally directed to systems and methods for improving quenched coke recovery. More specifically, some embodiments are directed to systems and methods utilizing one or more of a screen, barrier, or reflector panel to contain or redirect coke during or after quenching. In a particular embodiment, a quench car system for containing coke includes a quench car having a base, a plurality of sidewalls, and a top portion. The system can further include a permeable barrier covering at least a portion of the top of the quench car, wherein the permeable barrier has a plurality of apertures therethrough.

    Abstract: The present technology is generally directed to systems and methods of controlling or reducing the output rate of a coke oven through gas sharing providing an extended process cycle. In some embodiments, a method of gas sharing between coke ovens to decrease a coke production rate includes operating a plurality of coke ovens to produce coke and heated exhaust gases. In some embodiments, a first coke oven is offset in operation cycle from a second coke oven. The method further includes directing the heated exhaust gases from the first coke oven to the second coke oven while the second coke oven is mid-cycle. The heat transfer allows the second coke oven to extend its cycle while staying above a critical operating temperature. By extending the operational cycle while generally maintaining output per cycle, overall production is decreased.
