Abstract

A method is disclosed for operating a carbonization plant in which coking furnaces are periodically charged with preheated coal and the obtained coke is subjected to a dry cooling by a gaseous cooling medium, heat discharged from the dry cooling of the coke is used for the preheating of the coal, involving preheating the coal in a traveling bed drier having a heat exchange tube that is heated with hot gas or waste-heat vapor from the dry cooling of the coke. Preferred embodiments include withdrawing exhaust gas-containing vapors produced in the traveling bed drier from different levels; and superposing a fluidized bed drier upon the traveling bed drier.
