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.
Claims2
Travelling bed drier for pre-heating of coal in a carbonization plant employing pre-heated coal, said drier being arranged and constructed to permit the coal to flow therethrough via gravity and, comprising a heat exchange tube and frame means;
- said heat exchange tube displaying on its coal side surface-increasing means, said tube being accommodated in said frame means, said frame means having a side displaying vapor or hot gas entry connected to said tube, a conical tapering in the direction of its coal feed, as well as a plurality of drain connections at different levels on a side lying opposite said side displaying vapor or hot gas entry, said connections being for the discharge of exhaust gas-containing vapors released from the coal during pre-heating.
