Abstract:
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.
Abstract:
A retort (10) for producing charcoal, and a method of use thereof, the retort (10) having an inner vessel (140), for receiving wood to be converted into charcoal, and an outer vessel (20) containing the inner vessel (140) and defining an intermediate region between the inner vessel (140) and the outer vessel (20). The intermediate region including a burning region configured for burning fuel to heat the inner vessel (140); a flue (60) from the inner vessel (140) to a region outside the outer vessel (20), for conveying gas from the inner vessel (140) to the atmosphere; a feed pipe (210) from the inner vessel (140) to the intermediate region, for conveying gas from the inner vessel (140) to the intermediate region, wherein the entire length of the feed pipe (210) is located within the outer vessel (20).
Abstract:
The present technology is generally directed to systems and methods for optimizing the burn profiles for coke ovens, such as horizontal heat recovery ovens. In various embodiments the burn profile is at least partially optimized by controlling air distribution in the coke oven. In some embodiments, the air distribution is controlled according to temperature readings in the coke oven. In particular embodiments, the system monitors the crown temperature of the coke oven. After the crown reaches a particular temperature range the flow of volatile matter is transferred to the sole flue to increase sole flue temperatures throughout the coking cycle. Embodiments of the present technology include an air distribution system having a plurality of crown air inlets positioned above the oven floor.
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:
A method and apparatus for refurbishing eroded portions in coke oven doorjambs (3) including refurbishing apparatus (10) having a framework (11) attached to the coke oven structure adjacent the doorjamb. The framework supports a carriage (12) that is simultaneously moveable in an "X" axis direction and a "Y" axis direction within the boundary so that a machine-cutting tool (13), attached to the carriage, can be moved from one position directly to another position within the framework boundary. The machine-cutting tool is positioned to make cutting passes along new metal that is fused into the eroded portions (4) of the coke oven doorjamb.
