ANLAGE ZUR HERSTELLUNG VON ZEMENT MIT VERMINDERTEM AUSSTOß VON SCHADGASEN
A plant for production of cement clinker from raw meal, having a calciner for deacidification of the raw meal and a rotary furnace for sintering the deacidified raw meal to give cement clinker. The deacidified raw meal flows through a cyclone preheating stage into the rotary furnace. A reactor is provided upstream of the calciner on the flow path of the rotary furnace offgas to the calciner, to which an inlet for the rotary furnace offgas leads. A corresponding method of operating such a plant wherein fuel is added to the reactor in a superstoichiometric amount in relation to the residence time of the offgases in the reactor, such that carbon dioxide present in the offgases is reduced to carbon monoxide. At least one input air conduit for supplying input air, preferably coming from a tertiary air conduit, is provided at at least one point in the reactor.
