ABSTRACT The specification discloses a coke oven emission control system comprising a traveling hood for the quench car into which hot coke is pushed from the coke oven. The hood is independently supported by wheels traveling on rails and is of a length to cover the entire length of the quench car. The hood is moved by the movement of the quench car to and from a quench station, through beams at opposite ends of the quench car that are selectively raised and lowered into and out of a position for engagement with the hood. The top of the hood is provided with a central elongate hollow neck which projects upwardly into a longitudinally slotted exhaust duct paralleling the battery of ovens. The slot in the duct has a pair of parallel extending flexible sealing strips which are biased toward sealing engage- ment with each other across the slot and which separate to seal on the neck of the hood as it slides longitudinally along the duct. Selective communication is thus provided for flow of fumes, gas, smoke, particulates, etc. from the hood into the exhaust duct from the oven being pushed.
