Abstract

L'invention concerne la combustion, en plusieurs étapes, avec introduction de l'air comburant en differents endroits de la chambre de combustion, d'un combustible pauvre en gaz et difficilement inflammable. Le combustible (charbon pulvérulent rencontre tout d'abord de l'air primaire à au moins 500 degrés -600 degrés C, puis il brûle avec l'air secondaire à 350 degrés -400 degrés C (environ 50 % de l'air comburant total) et sa combustion est parachevée avec de l'air tertiaire à 250 degrés -300 degrés C (environ 35 à 40 % de la quantité totale d'air comburant). L'air comburant est chauffé dans des préchauffeurs disposés en série. Application : chauffage à l'anthracite d'un générateur de vapeur.
