COMBUSTION CONTROL METHOD OF REFUSE INCINERATOR

摘要

The present invention aims for the object thereof at preventing unburnt gas and noxious gas components from being generated in a refuse incinerator, and provides a combustion control method by which it is arranged so that a feeder 2 and a stoker 3 are not only controlled so as to keep evaporation S1 of the boiler at a target value thereby to achieve stabilized combustion extending over a long period of time, but also feed water quantity S2 and the like from a boiler water pipe panel section 2 forming a combustion chamber 6 are detected, and the rate of overfire air quantity to main combustion air quantity to a lower part of the stoker is controlled at a constant total gas capacity so that the fluctuation width of the feed water quantity S2 falls within a set range.
