EP0726437A1 - Oxygen lancing for production of cement ...

Oxygen (8) is lanced into the main combustion reaction of a cement kiln (2) to increase heat transfer to the clinker bed (3) and to increase clinker production. Oxygen is separately lanced along the floor (7), i.e. the lowest wall of the kiln (2), to delay mixing with the flame to provide deep staging. The deeply staged oxygen flow is adjusted frequently to control emissions and stabilize the ...
