Abstract
A one-spot hopper, provided with means for developing layers of coke therein, of even depth, is pivotally mounted to a frame that is movable alongside the coke side of a coke oven battery. Extendible and retractable covers close, and seal the hopper from the ambient atmosphere. A cylinder-piston means is used to pivot the hopper and dump coke therein through pivoted side plates of the hopper. Means are provided to also close off and seal the coke pushing operation of the coke oven battery from the ambient atmosphere. At least one perforated conduit extends transversely through the hopper, and a perforated shield is disposed in spaced-apart relation above the conduit. Means is provided for flowing a cooling fluid in the conduit. A duct is fitted to the hopper to provide a means for extracting gases and entrained particulate matter emanating from hot coke deposited in the hopper.
