Abstract

INSTALLATION FOR THE MANUFACTURE OF CEMENT BY DRY WAY WITH A PRE-CALCINATION CHAMBER, of the type that includes an oven, a preheater in which the raw material is heated by the smoke from the oven, a precalcining chamber located between the preheater and the oven, and a clinker cooler, in which the secondary air used in the combustion chamber and in the furnace is reheated by means of the calories of the clinker, characterized by the fact that it involves an indirect changeover changer that comprises two independent circuits respectively traveled by a fluid hot and a cold fluid and in which the secondary air used in the precalcining chamber is reheated by means of the high temperature air taken from the clinker cooler by means of a fan arranged after the exchanger.
