Abstract
The invention relates to an arrangement (1) for drying of municipal waste, in particular household waste, with a dryer (2) for drying of municipal waste by means of hot gas (7), with a burner (9) for generating the hot gas in a combustion chamber (18) by incineration of a gas. The arrangement also includes a vapor line (10) leading from the dryer to the burner space and at least a portion of the vapor from the dryer (2) is recycled to the burner chamber (18). It has been found that the energy input in the form of the generation of the hot gas (7) needed gas (15) can be significantly reduced if the vapor line (10) tangentially into the combustion chamber (18) opens. The remaining gas flow can therefore be used as an additional fuel, because they are at least partially oxidized exothermically in the combustion chamber. The exothermic oxidation by the tangential feed is considerably favored.
