Abstract
Procedure and installation for the manufacture of cement in rotary kilns, heated with the help of sulfur-laden fuel, the procedure characterized in that the fuel is desulfurized before being used as fuel in the kiln, the sulfur that comes from the desulfurization of the fuel is recovered To manufacture a sulfur compound such as, in particular, calcium sulfate or gypsum, and the sulfur compound obtained as an additive is used during the final cement elaboration.
