PURPOSE:To be able to reduce fuel consumption and carry out incinerating treatment effectively by a method wherein exhaust valves are installed at one or several stages locating above set burning stages and actual burning stages are detected and when the actual burning stages locate above the set burning stages, exhaust valves are operated. CONSTITUTION:Exhaust holes 22a, 22b are bored at the side wall of the fifth and sixth stages of an incinerator 1 and exhaust valves 23A, 23B are connected to the exhaust holes 22a, 22b through pipes. A fuel control valve 13 is controlled in such an opening where the temp. of set burning stages becomes the most optimum burning temp. in a set value by a thermometer 17. The temperatures of the three stages as drying zones and four to six stages as burning zones are detected by temp. detectors 7A-7D. Temperature T3-T6 detected by the temp. detectors 7A-7D are input into a judging circuit 18 for burning stages which detects actual burning stages and provides the detected temp. value T6 at the sixth stage in the set burning stages to a controller 17. The circuit 18 supplies information that the detected burning stages belong to which stages to a valve driving circuit 24 and also makes and breaks contacts 8A, 8B after judging whether the incinerator 1 is in preparation for burning or not.
