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.

Abstract: The present technology is generally directed to horizontal 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. 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.

Abstract: 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.
