Abstract: The present technology is generally directed to vent stack lids and associated systems and methods. In particular, several embodiments are directed to vent stack lids having improved sealing properties in a coke processing system. In a particular embodiment, a vent stack lid comprises a first lid portion proximate to and at least partially spaced apart from a second lid portion. The vent stack lid further comprises a first sealing portion coupled to the first lid portion and a second sealing portion coupled to the second lid portion. In several embodiments, the second sealing portion at least partially overlaps the first sealing portion over the space between the first and second lid portions. In further embodiments, at least one of the first or second sealing portions includes layers of tadpole seals, spring seals, rigid refractory material, and/or flexible refractory blanket.

Abstract: The present technology is generally directed to horizontal heat recovery and non-heat recovery coke ovens having monolith components. In some embodiments, an HHR coke oven includes a monolith component 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 monolith component comprises a thermally-volume-stable material. The monolith component may be a crown, a wall, a floor, a sole flue or combination of some or all of the oven components to create a monolith structure. In further embodiments, the component is formed as several monolith segments spanning between supports such as oven sidewalls. The monolith component 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 oven.

Abstract: A system and method for repairing a coke oven having an oven chamber formed from ceramic bricks. A representative system includes a insulated enclosure insertable into the oven chamber and includes removable insulated panels that define an interior area for workers to work in. The insulated enclosure is movable between an expanded configuration and a compact configuration and moving the enclosure to the expanded configuration will decrease the distance between the insulated enclosure and the walls of the oven chamber. Removing the panels exposes the ceramic bricks and allows workers within the interior area to access and the bricks and repair the oven chamber while the oven chamber is still hot. A loading apparatus lifts and inserts the insulated enclosure into the oven chamber. The insulated enclosure can be coupled to additional insulated enclosures to form an elongated interior area.

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.
