Abstract
An enclosed quenching car movable along a battery of coke ovens and adapted to receive coke from each oven in succession and quench it without polluting the atmosphere. The car includes an enclosure containing a pivotal quenching tank with interior dimensions substantially corresponding to the dimensions of the carbonized coke cake to be accommodated therein. One side of the pivotal tank is formed from a water-permeable grid such that the coke cake within the tank can be rotated into a horizontal plane and the coke completely immersed in water passing through the permeable grid; while dust and gases are extracted without polluting the atmosphere. In this manner, the coke is quenched in such a way that it is yielded in large pieces with a defined uniform water content in the coarse and fine coke.
