Method of producing cement clinker from chlorine-containing raw mixture

Abstract

The herein-proposed method of producing cement clinker from a chlorine-containing raw mixture, comprising the steps of introducing said mixture into a kiln, sintering of the mixture, removing chlorine-containing compounds from the resultant sinter by acting on the sinter with a steam-gas-and-air mixture, subsequently regenerating the chlorine-containing compounds and cooling the resultant clinker, is characterized by the fact that the sinter is suspended in the steam-gas-and-air mixture, and the regeneration of the chlorine-containing compounds is carried out by spraying the raw mixture in a stream of chlorine-containing flue gases.
