Abstract

Procédé de cuisson de matières minérales. L'air de refroidissement chauffé par les matières premières cuites dans la zone de refroidissement est entraîné hors du four à la fin de la zone de refroidissement au moins partiellement et sa capacité calorique est récupérée et utilisée en dehors des chambres du four pour préchauffer les matières premières à introduire dans le four et/ou pour préchauffer l'air de combustion qui est amené par l'extrémité supérieure de la zone de préchauffage. Cuisson de la pierre à chaux, de la dolomite, de la magnésite et analogue.Process of cooking mineral materials. The cooling air heated by the raw materials fired in the cooling zone is drawn out of the furnace at the end of the cooling zone at least partially and its heat capacity is recovered and used outside the furnace chambers to preheat the materials. first to introduce into the furnace and / or to preheat the combustion air which is supplied by the upper end of the preheating zone. Firing of limestone, dolomite, magnesite and the like.
