Abstract

IMPROVEMENTS IN FACILITIES FOR THE MANUFACTURE OF CEMENT BY DRY WAY, involving a firing furnace, a combustion chamber arranged before the furnace, considering the direction of movement of the material, a multi-stage preheater in which the material is finely divided is suspended in the fumes of the furnace and the combustion chamber, and a cement slag cooler (clinker), characterized in that they comprise at least two air reheating units, with indirect thermal exchange, located in series on the path of the air that feeds the combustion chamber and heated by at least a fraction of the fumes from the furnace and the combustion chamber to carry out a countercurrent exchange between the air and the fumes, of which superheater at least one is located at the exit of an intermediate stage of the preheater.
