Abstract: Systems and methods for particle leak detection generally include a separation or collection device configured to filter particulate from a stream and a detection device downstream of the separation or collection device. The detection device can be positioned to detect particulate that passes the separation or collection device and can include a probe configured to detect the solid particles. The particle leak detection systems can be configured to be disposed on moveable systems, such as moveable systems in coke oven operations.

Abstract: The present technology describes various embodiments of systems and methods for maintaining a flat push hot car. In some embodiments, the flat push hot car includes an at least partially enclosed hot box having an interior portion, an exterior portion, a base, and a plurality of sidewalls extending upward from the base. The hot box can he coupled to or integrated with a fluid distribution system. The fluid distribution system can include a spray manifold having one or more inlets configured to release a fluid directed toward the sidewalls of the interior portion so as to provide regional cooling to the hot box.

Abstract: A coke oven can include an oven body, a foundation, and a plurality of beams separating the oven body from the foundation. A buckstay applies force to the oven body to maintain compression on the oven body during thermal cycling of the coke oven. The coke oven further comprises a spring-loaded compression device, which can include a restraining device, an anchor coupled to the restraining device, and a spring coupled to the restraining device. The anchor can be attached to one or more of the beams, the foundation of the oven, or to a similar compression device on an opposite side of the oven. The spring applies force between the restraining device and the one or more beams or foundation to compress the buckstay against the oven. The force applied by the spring can maintain structural stability of the coke oven over a plurality of thermal cycles.

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 is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.
