Abstract

A travelling bed drier is disclosed, for operation of a carbonization or coking plant in which pre-heating of coal is performed. Adapted so that a fluidized bed drier can be superposed thereon, the travelling. bed drier possesses a heat exchange tube within a frame, the tube displaying a surface increased through suitable design such as fins or ribs, a conical tapering in the direction of the coal feed, and discharge connections located at different levels on a side of the frame lying opposite vapor or hot gas entry, the connections being for the discharge of exhaust gas-containing vapors.
