Abstract

A rotary kiln (18) includes a novel air conveying system for delivering a supply of port air beneath the material bed of feed stock passing through the interior of the kiln. The air conveying system includes an air inlet port (50) disposed in the shell of the kiln, a main air conveying channel (85) which communicates with the air inlet port, and a plurality of air vent channels (75) communicating with the main air conveying channel and the interior chamber of the kiln. The main air conveying channel (85) is formed integrally in the refractory bricks which line the inner surface of the kiln shell and extends longitudinally and parallel to the rotary axis of the kiln. The air vent channels (75) extend through the refractory bricks substantially radially with respect to the rotary axis of the kiln.
