Abstract

An improved duct system is provided for collecting gases from the coke side of a battery of coke-oven chambers with vertical flues in which a coke guide is mounted for movement along the ovens on rails, in which the coke transport car is mounted for movement on rails along the ovens adjacent the coke guide, and in which a stationary main collection duct with a belt covered slot is provided adjacent the transport car rails. An extraction hood is provided for covering the transport car and connecting the discharge end of the coke guide with the transport car. The hood has an integral connecting line adapted to be connected between a gas collection duct above the coke guide and a gas transfer device movable on the main duct under the belt for directing the gases into the main duct. Also integral with the extraction hood are two gas outlet ducts, one on each side of the connecting line, separate from the connecting line, for connecting the extraction hood to the gas transfer device.
