Abstract
A coke oven fumes control system includes a duct-and-car arrangement extending alongside the coke oven quench car track. The car of the duct-and-car system supports a hood movable into overlying relation with a selected portion of the quench car. An additional hood overlies the coke guide. A system of connecting ducts connects the coke guide hood through the quench car hood to the car of the duct-and-car arrangement, thereby providing evacuation of both the quench car hood and the coke guide hood. The quench car hood is divided into a plurality of sectors. Butterfly valve dampers are provided for controlling evacuation of the various sectors of the quench car hood, as well as the coke guide hood.
