Abstract
L'invention porte sur un procédé ainsi que sur une installation pour la production simultanée d'électricité et de clinker de ciment. Selon ce procédé, une farine de ciment de départ est calcinée dans un four de calcination (4) soumis à une introduction simultanée de combustible et d'air de combustion, puis grillée en clinker de ciment dans un four (5), et une partie de la chaleur contenue dans les gaz d'échappement provenant du four de calcination (4) est utilisée pour générer de l'électricité au moyen d'une section de chaudière (18). Le procédé et l'installation sont particuliers par le fait que l'air de combustion adressé au four de calcination (4) ne contient pas d'alcali ni de chlorure, et par le fait que la température des gaz d'échappement utilisés pour générer l'électricité est d'au moins 500 °c. On obtient de cette façon que des formations de revêtement formées sur les tubes de chaudière en raison de la condensation de vapeurs d'alcali et de chlorure peuvent être évitées, tandis qu'en même temps, le rendement avec lequel une énergie thermique peut être convertie en énergie électrique peut être augmenté.
