Abstract

A kiln plant for producing cement of other clinker from chloride-containing raw material has a kiln (2), a suspension preheater (4,5,6,7) through which kiln exit gas passes to a precipitator (8), and a by-pass conduit (11,14) through which a portion of the kiln exit gas passes via an air quenching unit (12) to the precipitator without encountering any further precipitator.
