ABSTRACT:
Coke from a non-recovery type coke oven is pushed onto a downwardly-inclined floor within a smoke hood joined along one edge of the coke oven. The coke is quenched by water discharge nozzles inside the hood. The coke is discharged through a gate at the bottom edge of the floor onto a conveyor after quenching is completed. The smoke and effluent within the hood pass into the top of two interconnected ignition chambers filled with checkerbrick to incinerate the effluent after which it is drawn from the top of the last ignition chamber into a conduit for discharge by a stack. The ignition chambers include walls isolating the flow spaces for the smoke and quenching fumes from the other flow spaces within checker-filled portions that conduct countercurrently partially-burned distillation products delivered by sole heating flues and downcomers from the space above a coal charge in the coke oven chamber. The ignition chambers are disposed between two coke oven chambers so that the partially-burned distillation products from these coke oven chambers are passed for incineration in the ignition chamber. The space beneath the smoke hood is subdivided by vertical walls forming compartments within the smoke hood each associated with two coke oven chambers and the ignition chambers therefor. Draft changeover valves are closed only when it is desired to draw smoke and the effluent from a chamber under the smoke hood into the ignition chambers.
