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 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.
