A locomotive is provided to move a quench car and a gas transition car parallel to a battery of coke ovens adjacent a coke guide car. A pivotable hood is provided on the guide car for covering part of the charging opening of the quench car. The quench car has generally parallel, pivotal flaps which can operate independently to open a portion of the quench car charge opening beneath the hood as coke is pushed from the guide and through the hood into the car. The flaps on either side of the hood can be held closed to seal the charge opening and prevent escape of the dirty gases out of the quench car. An extraction duct connects the quench car to the gas transition car cooperably connected with a gas collection duct which also runs parallel to the coke ovens and which has an opening running its length. The opening is sealed by a belt, a portion of which is lifted away from sealing engagement with the collection duct by the gas transition car to allow passage of gases into the collection duct and then to gas extraction and purifying equipment.

Equipment for extracting and purifying dirty gases arising on the coke

A hood car having a hood, a coke guide, a coke guide car, and a quench train are all provided for movement parallel to a battery of chamber coke ovens between a quench plant and the ovens. The hood car hood has an opening reaching over the loading area of the quench train and is adapted to be connected through extraction ducts to a gas transition device which is movable on a stationary collection duct alongside the coke oven battery and which has an opening at the top. The opening can be sealed by a flexible cover belt which can be lifted off by the gas transition device. The collection duct is connected to a stationary extraction and purifying device which purifies the dirty gases. The movable hood car and the quench train have coupling means, functional in both directions of movement, for coupling together the hood car and the quench train. The hood car has a brake means for automatically stopping the car upon being uncoupled from the quench train. According to the method of the present invention, the quench train is moved to the quench plant with the hood covering the quench train. Before the train enters the quenching plant, the hood is uncoupled and is automatically braked until it comes to rest. The hood is recoupled to the quenching train as soon as the quenching train has moved out of the quenching plant and has moved under the hood.
