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: 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.
