ABSTRACT:
A rotary kiln with primary air feed at the end wall of the rotary kiln is distinguished by the feature that at least two primary air nozzles are oriented relative to each other and to the fuel bed so that two oppositely directed vortices are generated within the rotary kiln, the axes of rotation of said vortices extending substantially parallel to the axis of the rotary kiln and said vortices rotating about said axes of rotation so as to promote the thermal convection-induced motion of the combustion gases.
