Abstract

L'invention concerne un procédé de remplacement d'une partie d'une huile combustible par du charbon minéral ou végétal brut dans la fabrication du ciment. Ledit procédé consiste à brûler du charbon minéral ou végétal brut dans le système de préchauffage des fours à clinker de ciment sans pulvérisation ni broyage préalable dudit charbon. Application au système de préchauffage d'une installation de fabrication de ciment.The invention relates to a process for replacing part of a fuel oil with raw mineral or vegetable coal in the manufacture of cement. Said process consists in burning raw mineral or vegetable coal in the preheating system of cement clinker kilns without pulverizing or prior grinding said coal. Application to the preheating system of a cement manufacturing installation.
