Soft brown coal drying method for e.g. heating boiler plants, involves disintegrating brown coals with water contents by crushing coals into grain size until exceeding surface-wet conditions of coals by intensive pressure
The method involves disintegrating soft brown coals with water contents by crushing the soft brown coals into grain size until exceeding surface-wet conditions of the brown coals by intensive pressure and/or shear stress or by dynamic stress and/or friction stress. The soft brown coals are dried by a steam-heated pipe dryer and smaller portions of airborne dust are separated from vapors of the pipe dryer. The dried coals are treated to increase hardness and very low dust characteristics.
