Title (EN) ADDITIONS OF CLAY AND SLAG MATERIALS TO COAL COMBUSTION BOILERS
(FR) AJOUTS DE MATÉRIAUX ARGILEUX ET CONSTITUÉS DE SCORIES À DES CHAUDIÈRES BRÛLANT DU CHARBON
Abstract: front page image
(EN) A method of combusting coal in the presence of a clay additive and a slag additive is disclosed. The combustion may occur in a coal combustion burner of a coal-fired electrical power generation plant. Co-injections of clay and slag improve operational efficiency of coal fired boilers by improving combustion, thermal heat transfer, steam output and/or electrical power output. The co-injections of clay and slag may also reduce unwanted emissions. The combustion product may be used as a pozzolanic addition to cement.
(FR) L'invention concerne un procédé de combustion de charbon en présence d'un additif argileux et d'un additif constitué de scories. La combustion peut se produire dans un brûleur de combustion de charbon d'une centrale électrique au charbon. Des co-injections d'argile et de scories améliorent l'efficacité de fonctionnement de chaudières au charbon par l'amélioration de la combustion, du transfert thermique, de la production de vapeur et/ou de la production d'énergie électrique. Des co-injections d'argile et de scories peuvent également réduire des émissions non voulues. Le produit de combustion peut être utilisé comme additif pouzzolanique pour du ciment.
