PROBLEM TO BE SOLVED: To obtain an incinerator emitting no harmful substance, e.g. dioxin, by coupling the incineration ash outlet of a furnace body with a dostal through an air circulation pipe and disposing an air intake fan in the vicinity of inlet of the air circulation pipe and an ignition fan in the vicinity of outlet thereof. SOLUTION: The incineration ash outlet 10 of a furnace body 1 is coupled with a flame combustion nozzle 9 through an air circulation pipe 2 and air containing ash, smoke and unburnt gas is circulated. An air intake fan 4 is disposed in the vicinity of inlet of the air circulation pipe 2 and air is taken in at such an angle as the smoke and air are circulated through the air circulation pipe 2 from the incineration ash outlet 10 and directed toward the flame combustion nozzle 9. Furthermore, an ignition fan 6 is disposed in the vicinity of outlet of the air circulation pipe 2 and the air containing ash, smoke and unburnt gas, passed through the air circulation pipe 2, is fed again to the furnace body 1.
