ABSTRACT:
In a method for reducing the amount of chloride components in cement clinker kilns at least a portion of the chloride-containing gases is removed from the kiln chamber. The gases are guided into a condenser whereby the gas temperature is maintained at a value above the condensation temperature of the chloride components. The chloride components are then cooled on cooled condensation surfaces of the condenser to a value below the condensation temperature. The cleaned gases are removed from the condenser and preferably returned into the kiln chamber. The condensation surfaces are continuously or discontinuously cleaned, and the removed chloride crystals are taken out of the condenser.
