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 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: Systems and methods for removing carbonaceous clinker material from a coke oven are described. A coke oven can be provided including an oven floor, coke, and clinker material deposited on the oven floor. After a temperature of the coke oven has reached a first temperature (e.g., after heating coal in the oven to produce coke), the method includes increasing the temperature of the coke oven to a second temperature that is higher than the first temperature for a predetermined amount of time. After the predetermined amount of time, the temperature is reduced to a third temperature that is lower than the first temperature.

Abstract: The present technology relates to systems and methods for reducing leaks in a system for coking coal. For example, some embodiments provide systems and method for treating a cracked or leaking surface in a system for coking coal. In particular, the present technology includes systems having one or more substances configured to reduce an airflow through one or more cracks by creating an at least partially impermeable patch. The present technology further includes methods for treating surfaces having one or more cracks to reduce an airflow through the one or more cracks.

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: Systems and apparatuses for controlling oven draft within a coke oven. A representative system includes an uptake damper coupled to an uptake duct that receives exhaust gases from the coke oven and provides the exhaust gases to a common tunnel for further processing. The uptake damper includes a damper plate pivotably coupled to a refractory surface of the uptake duct and an actuator assembly coupled to the damper plate. The damper plate is positioned completely within the uptake duct and the actuator assembly moves the damper plate between a plurality of different configurations by causing the damper plate to rotate relative to the uptake duct. Moving the uptake damper between the different configurations changes the flow rate and pressure of the exhaust gases through the uptake duct, which affects an oven draft within the coke oven.
