Abstract
IMPROVEMENTS IN THE FACILITIES FOR THE MANUFACTURE OF CEMENT BY DRY WAY, of the type that involves a rotary kiln and a multi-stage preheater successively crossed by the fumes and the kiln in which the finely divided materials are suspended in the fumes and in each stage, passing from one stage to the next, circulating in the opposite direction to the fumes, and also a boiler heated by the fumes from the oven, which improvements are characterized by the fact that the boiler is located on the smoke path between two preheater covers, and why, eventually, a small excess of calories is added to the oven so that the boiler is heated by the fumes at a relatively high temperature, above 400ºC.
