摘要： 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 be 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.

摘要： 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.

摘要： Systems and methods of dynamically charging coal in coke ovens related to the operation and output of coke plants including methods of automatically charging a coke oven using a charging ram in communication with a control system to increase the coke output and coke quality from coke plants. In some embodiments, the control system is capable of moving the charging ram in a horizontal first direction, a horizontal second direction and a vertical third direction while charging coal into the oven. In some embodiments, the coal charging system also includes a scanning system configured to scan an oven floor to generate an oven floor profile and/or oven capacity. The scanning system used in combination with the control system allows for dynamic leveling of the charging ram throughout the charging process. In some embodiments, the charging ram includes stiffener plates and support members to increase the mechanical strength of the charging ram and decrease the sag of the charging ram at a distal end.

摘要： The present technology is generally directed to coal charging systems used with coke ovens. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly 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, charging plates extend outwardly from inward faces of opposing wings.

摘要： 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.

摘要： A coke oven includes an oven chamber configured to support and heat a coal bed, a castable slab below the oven chamber, and a foundation supporting the heat recovery oven. One or more beams are positioned between the castable slab and the foundation. The beams extend from a first end of the oven chamber to a second end of the oven chamber, forming a plurality of air gaps between the castable slab and the foundation. Heat from the oven chamber is dissipated by the one or more beams.

摘要： The present technology is generally directed to methods of increasing coke production rates for coke ovens. In some embodiments, a coal charging system includes a false door system with a false door that is vertically oriented to maximize an amount of coal being charged into the oven. A lower extension plate associated with embodiments of the false door is selectively, automatically extended beyond a lower end portion of the false door in order to extend an effective length of the false door. In other embodiments an extension plate may be coupled with an existing false door having an angled front surface to provide the existing false door with a vertically oriented face.
