Abstract
A charging car supports a plurality of hoppers in a manner such that two hoppers for supplying coal to adjacent charging holes are supported one after the other in a consecutive relationship along a line which is generally parallel to movement by the charging car. A conveyor conducts coal from each hopper to a telescopic charging tube which communicates with the charging hole in the roof of a coking chamber. Skirt-like walls enclose the sides of the spaces containing two of the hoppers to conduct smoke and other gases upwardly toward a roof which is supported by stanchions at each side of the battery of coke ovens. In one embodiment, two roof sections extend from the sides of a battery of coke ovens toward the center thereof. Gas-conducting mains receive gases via outlet pipes having control valves from the spaces beneath the roofs.
