Abstract

Plant for mfg. cement by a dry method, utilises a furnace, a preheater in which the raw material is heated by exhaust gas from the furnace, a pre-calcining chamber located between preheater and furnace, and a cooler for the cement clinker, the secondary air used in the combustion chamber and the furance being heated in the cooler for the clinker. An indirect exchanger is used comprising two independent circuits for a hot fluid and a cold fluid, and in which the secondary air for the pre-calcining chamber is heated by high-temp. air obtd. from the clinker-cooler with the aid of a blower placed downstream of the exchanger. Max. utilisation of the heat available from the clinker-cooler is thus obtd., with easy control of the flow of secondary air.
