METHOD OF UTILISING PHOSPHORUS-CONTAINING ALTERNATIVE FUEL IN CEMENT PRODUCTION Russian patent published in 2015 - IPC C04B7/44 C02F11/00 

FIELD: chemistry.

SUBSTANCE: method of utilising a phosphorus-containing alternative fuel in the production of cement clinker, in which the alternative fuel is thermolysed with the application of heat, formed in one of various thermolysis reactors with a rotating tubular furnace and discharged from the technological process of cement clinker production, the released energy is supplied into the technological process of cement clinker production, and residues of the thermolysis of the phosphorus-containing alternative fuel are discharged from the thermolysis reactor, is characterised by the fact that the residues of the thermolysis of the phosphorus-containing alternative fuel are converted in the thermolysis reactor into halogenide carriers by means of bypass products of a cement furnace with discharge of halogenides of heavy metals. The invention is developed in dependent claims of the invention formula.

EFFECT: reduction of the chloride concentration in the technological process of cement clinker production.
