Abstract

a. Procédé et dispositif d'allumage de mélanges de frittage contenant un combustible solide, dans des installations de frittage, au moyen de gaz de combustion chauds, le degré d'utilisation d'oxygène desdits combustibles gazeux ou liquides étant supérieur à 0,9. b. Suivant l'invention, les combustibles gazeux ou liquides sont prébrûlés et mélangés avec des gaz contenant de l'oxygène avec formation d'un tourbillon dans des chambres de combustion précédant le four de frittage, puis ils sont amenés dans le four. c. Le procédé convient aussi bien pour le frittage de minerais de fer que pour celui des minerais de métaux non ferreux.
