Abstract

Claims13
A method of refining solid fuel of organic vegetable material, which fuel is dried with utilization of drying gases, characterized in that the fuel is supplied to a mill together with an adjusted amount of drying gases, in which mill the material is disintegrated to finely distributed state and dried simultaneously with said disintegration, whereafter the dried disintegrated material is transported pneumatically by the drying gas from said mill and is further dried in at least one pneumatic drying step, and the material thereafter is separated from the drying gas to produce refined solid fuel.
