Abstract

Apparatus for reducing the water content of water-containing, granular brown coal under the action of thermal energy and pressure on the material (14) distributed flat in bed form using a press (9, 10) in which the brown coal is subjected to a mechanically applied initial surface pressure and which is furnished with orifices (21) for feeding steam (HD) which, supplying thermal energy to the brown coal, heats this, with condensation, and the hot water (HW) contained in the heated brown coal is expressed for use as a waste-heat source, a vessel (30) being provided for collecting the hot water (HW), from which vessel the hot water (HW) is passed to the orifices (21) in the press (9, 10), and which vessel is furnished with an inlet for the steam (HD) for expelling the hot water (HW).
