ABSTRACT:
The process for low-emission drying of a substance in a drum-type drying installation is suitable in particular for sewage sludge, fish meal and sludges from starch factories, soap factories and paper mills, which substances are preferably to be converted into granules. The process is likewise very suitable for drying biomass products such as wood chips, grass, sugar beet chips and the like, since the emissions are very greatly reduced by means of this process. The drying process is carried out in such a way that no unpleasant odors and dusts are emitted to the outside, because the actual drying circulation is closed. Fossil fuels are used as the heat source for the burner for heating this air stream.
