摘要

In a generally known cement kiln plant, which comprises a preheater (1) with calciner (2) and separation cyclone (3), a rotary kiln (4) and a clinker cooler (5), a decomposition chamber (10) is additionally installed for incineration of waste. Waste is introduced into the chamber at (12) and decomposed in the chamber by means of the heat from calcined raw meal which is conveyed to the chamber from the separation cyclone (3) of the calciner via a splitting gate (13) and a pipeline (14). Gaseous products are conveyed to the calciner (2) and burned there, whereas non-decomposable by-products are discharged via an outlet (15) in the chamber (10). By utilizing heat from calcined raw meal for incineration of waste instead of for example hot exhaust gases, any disturbance of the draught conditions of the plant can be avoided, and the overall control of the calcining process is improved.
