PROBLEM TO BE SOLVED: To provide a combustion furnace of industrial/domestic waste for efficiently taking out combustion gas from a packing waste material, a tire, garbage and the other various inflammable wastes (hereinafter referred to only as industrial/domestic waste) generated from a plant, a business place, a store or a home. SOLUTION: This combustion furnace generates combustion fumigation gas by fumigation of the inflammable industrial/domestic waste, and has a cylindrical base body having a tapering-off lower part. The base body has a firebed device having an input port for inputting the industrial/domestic waste, a lower opening for taking out the fumigation gas from the burning industrial/domestic waste and dropping incineration ash, a rotatably driven vertical support shaft extending to the center of the lower opening and a firebed arranged on this support shaft, winding a heat resistant raw material in a conical shape and a spiral shape rising upward toward the inner periphery from the outer periphery with dropping clearance of the incineration ash and closing the lower opening with the dropping clearance. The firebed device fixes the winding start end of the outer periphery of the firebed to the support shaft toward the preceding side of rotation, and rotates together with rotation of the support shaft.
