<p>A combustion controller (62) controls the supply of combustion air to the combustion barrel (10) of a rotary combustor (8) used for incinerating solid waste material (14). The rotary combustor (8) includes a combustion barrel (10) having a gas-porous side wall (36) and windboxes (48, 50, 52) underneath the combustion barrel (10) to supply the combustion air to support incineration of the waste material (14) into combustion products which include exhaust gases (20). The windboxes (48, 50, 52) receive combustion air via individual control ducts (40, 42, 44, 46, 47, 49) which are controlled by the combustion controller (62) to regulate the corresponding supplies of combustion air and thereby to provide substantially complete incineration of the solid material (14). An oxygen sensor (64) detects the percentage of oxygen present in the exhaust gases (20) and the combustion air supplied to the combustion barrel (10) is controlled to maintain the percentage of oxygen near a predetermined level. In addition, flame and temperature sensors (71 through 79) may detect temperature and the existence of a flame (26) respectively, in an area above each of the windboxes (48, 50, 52) so that the combustion air supplied to each windbox (48, 50, 52) can be individually controlled.</p> |
