Abstract (en)

The flame comprises a primary combustion zone for e.g. fuel and oxidant, close to the fuel and oxidant injection points (23, 22). In addition the flame comprises a second combustion zone downstream, where a second fuel (24, 25) (low quality) and oxidant (21) burn. The second fuel is preheated by passage through the primary flame zone.

Abstract (fr)

Procédé de combustion applicable notamment à la cimenterie, dans lequel on veut utiliser des combustibles qui s'enflamment difficilement. Pour cela, on crée une flamme comportant une zone primaire et une zone secondaire. La zone primaire, chaude, est créée à l'aide d'une flamme oxy-combustible, qui permet de préchauffer le combustible qui s'enflamme difficilement de manière à l'amener à la température adéquate dans la zone secondaire où il brûle, avec de l'air, pour créer la flamme principale. Applications : ciment, métallurgie, verre,...
