INCLINED KILN FOR THE FIRING AND SINTERING OF MATERIAL AND A METHOD FOR OPERATING SAID KILN

摘要

An inclined kiln having an inclined run off surface bounded laterally by side walls, is provided with at least three burners for playing on different longitudinal zones of the runoff surface, the burners being controllable independently of each other for differential heating of the respective zones. Spent, burnt gases are drawn along the runoff surface and led from the upper end thereof to a recuperator in which the burnt gases give up heat for the pre-heating of atmospheric air for combustion of the burners.
