ABSTRACT:
The present invention is directed to a method for controlling the kiln gas stream in a conventional long wet or dry process cement kiln modified for delivery of solid fuel into the calcining zone. Air is injected into the kiln gas stream at a point downstream of the clinkering zone and upstream of the drying zone to promote combustion efficiency downstream of the clinkering zone.
