<p>This invention relates to a process and a device for treatment, comprising at least drying, of preferably peat and the object thereof is reduction of the moisture percentage to the lowest possible level with a low supply of energy and simultaneously making the peat so compact in dried state that it can be easily stored, conveyed and handled and does not give off dust. According to the invention the material (13) to be dried is heated to such an extent that the water therein will boil and vaporize, the vapour formed being carried away from the material by means of air (15) streaming through this, which air is led to a heat exchanger (20) for heating supply air from outside, which is utilized to form the air stream (15) through the material, and for heating of the combustion air to a combustion furnace (8), the fumes (11) of which are utilized for heating the material.</p> |
