ABSTRACT:
In a dried sludge melting furnace apparatus, at least one of following two controls is executed. In one of the controls, the primary combustion chamber (PCC) upper combustion air supply amount and the PCC lower combustion air supply amount are adjusted so as to respectively become a target PCC upper combustion air supply amount and a target PCC lower combustion air supply amount which are obtained from an inferred PCC upper combustion air supply amount and an inferred PCC lower combustion air supply amount. The inferred PCC upper and lower combustion air supply amounts are obtained by a fuzzy inference device (221). In the other control, the total combustion air supply amount and the second combustion chamber (SCC) burner fuel supply amount are adjusted so as to respectively become a target combustion air supply amount and a target SCC burner fuel supply amount which are obtained from an inferred combustion air supply amount and an inferred SCC burner fuel supply amount. The inferred combustion air supply amount and the inferred SCC burner fuel supply amount are obtained by a fuzzy inference device (222).
