Drying of peat

Electric endosmose is of technical importance for the dehydration of organic, finely suspended substances containing1 very much water, for example, the drying of peat, according,...

At Helsinki University of Technology, successful demonstration of fluidized bed drying of peat has been reported at the pilot plant level (100 kg/ h of water evaporated). A tubular heat exchanger immersed in the bed provides indirect heat for drying. It uses condensing steam at 0.8 MPa. Steam evaporated from peat is used as the fluidizing medium. Wet peat is fed into the lower zone of the fluid bed while dry peat is withdrawn from the upper zone by a screw conveyor. The miffed peat is about 1 mm in average size. The...
