Abstract

Method of drying lignite, characterized by the fact that after pouring the lignite to a drying column (1), hot air is circulated as long as assumed humidity is given off by the raw material, whereby circulation of air is causing humidity transfer through the layers of coal and some air circulates in the chamber as long as proper max. saturation is effected, then the humidity is removed by cooling by a heat exchanger (3) and re-heated to the working temperature. The direction of air circulation in the drying chamber is reversible in the drying cycle process. Device for drying the lignite coal according to the method of Claim 1, characterized by the fact that contains at least one module of the drying chamber (1), consisting of a thermally insulated casing (10) with air exchange windows (7) and (8) on the whole width of the column and at some part at this height of the working (W) column's part, on one or both sides heat exchangers (3) and axial fans (2) separating the chamber into upper and lower air circulation parts.
