Abstract

Procédé de fabrication de clinker pauvre en composés alcalins à partir d'une matière première renfermant des composés alcalins, par un traitement thermique étagé de celle-ci dans un étage de préchauffage, un étage de calcination, un étage de frittage et un étage de refroidissement, avec apport de chaleur par un combustible de nature quelconque dans l'étage de calcination ainsi que dans l'étage de frittage. Installation pour la mise en oeuvre de ce procédé. Les gaz s'échappant de l'étage de frittage sont refroidis par mélange avec un fluide gazeux plus froid et le gaz mixte ainsi formé est utilisé ensuite dans l'étage de préchauffage comme fluide cédant de la chaleur en contact direct à la matière première. Dans l'installation comportant des appareils pour le préchauffage, la calcination et le frittage de la matière première pour le ciment, ainsi que pour le refroidissement du clinker, l'appareil de préchauffage 2 est précédé, du côté gaz, d'un dispositif 16 pour mélanger au gaz d'échappement de l'étage de frittage 6 un fluide gazeux plus froid.Process for manufacturing clinker poor in alkali compounds from a raw material containing alkali compounds, by a staged heat treatment thereof in a preheating stage, a calcination stage, a sintering stage and a cooling stage , with heat input by any type of fuel in the calcination stage as well as in the sintering stage. Installation for the implementation of this process. The gases escaping from the sintering stage are cooled by mixing with a cooler gaseous fluid and the mixed gas thus formed is then used in the preheating stage as a heat-releasing fluid in direct contact with the raw material. In the installation comprising apparatus for preheating, calcining and sintering of the raw material for cement, as well as for cooling the clinker, the preheating apparatus 2 is preceded, on the gas side, by a device 16 for mixing a cooler gaseous fluid with the exhaust gas from the sintering stage 6.
