An arrangement for drying and preheating coking gas has a transport tube for transporting coal in a stream of a carrier gas , and a feed conduit for feeding hot gas into the transport tube. The feed conduit is movable relative to the tube so as to vary the conditions of feeding the hot gas into the transport tube. For this purpose, feed conduit may be connected with the transport tube by a ball-and-socket joint, so that it can be movable relative to the transport tube in circumferential and axial directions of the latter. The feed conduit may be composed by a plurality of conduit members located in the transport tube and one in the other, and movable relative to transport tube in the axial direction of the latter.
