The auxiliary fuel is supplied to the combustion chamber when a valve(33) is opened and an auxiliary fuel feed pump is started. A long lighter type ignitor is inserted/ignited through an ignition hole(16) to ignite the auxiliary fuel and then the powder type inflammable waste matter. The secondary combustion air is circulated through the circulating path(A) to promote combustion of the auxiliary fuel and the inflammable waste matter. When reforming water is injected to the combustion chamber, the secondary combustion air is mixed with the reforming water to react with a flame of the inflammable waste matter chemically. Thereby, the waste matter is completely burned at 180deg.C. In the incinerating process, smoke, odor, noxious gas and environmental hormones are rarely exhausted.
