FIELD: chemistry.SUBSTANCE: method of processing wet wastes containing organic substances, particularly sludge, in an apparatus for producing cement clinker, the method comprising heating raw meal in a heater in counterflow conditions with host waste gases of a furnace for burning clinker and calcining in a calciner in which alternative fuel is burnt. The wet wastes are dried in a dryer using hot gas obtained from waste heat of the heater, wherein the waste heat of the heater is removed from the heater in at least two different points of the heater at two different temperature levels so as to generate at least two streams of waste heat, and temperature of the hot gas fed into the dryer is controlled by selecting the ratio of the mixed streams of waste heat, and the dried wastes and exhaust gases of the dryer are removed from the dryer, and exhaust gases of the dryer are fed into the calciner.EFFECT: processing wet wastes.35 cl, 1 dwg |
