Exhaust hood for coke oven quenching car
Abstract
Abstract A quencher car runs along a track in front of a carriage that is movable along the front of a battery of coke ovens and that supports a tubular coke guide through which coke can be pushed from any oven into the quencher car. The carriage also carries a fume-collecting hood that projects laterally from it over the track to over- lie the quencher car. The hood has an inner side wall provided with an opening registering with the outlet of the guide. An exhaust pipe secured to the hood has an inlet in the upper part of the hood. A suction duct extends lengthwise of the track beside the outer side wall of the hood, and the outlet of the exhaust pipe communicates with the inside of the suction duct and is movable lengthwise thereof by the carriage.
