METHOD FOR RECOVERING PHOSPHORUS-CONTAINING ALTERNATIVE FUELS IN CEMENT PRODUCTION

摘要

In a method for recovering phosphorus-containing alternative fuels in cement clinker production, the alternative fuels are thermolyzed using waste heat from the cement clicker production process in a thermolysis reactor different from a rotary kiln of the cement clinker production process, the energy thereby released is supplied to the cement clinker production process and the thermolysis residues of the phosphorus-containing alternative fuels are discharged from the thermolysis reactor, and so the thermolysis residues of the phosphorus-containing alternative fuels are mixed in the thermolysis reactor with cement kiln bypass products as halogen carriers and the heavy-metal halides produced are drawn off.
