PROBLEM TO BE SOLVED: To provide a waste disposal device capable of elongating a useful life of a furnace wall of a gas reforming furnace. SOLUTION: In this waste disposal device having a gasification melting furnace 5 for partially oxidizing-gasifying, and melting the waste, and the cylindrical gas reforming furnace 5b having an oxygen-containing gas supply opening 44 disposed in a state of being connected with an upper section of the gasification melting furnace, and reforming the gas produced in the gasification melting furnace, a gas duct 40 for discharging the gas from the gas reforming furnace is disposed on a top peripheral wall of the gas reforming furnace, one of conditions that the direction of the gas duct on a horizontal cross-section of the gas reforming furnace is (A) the tangential direction and is (B) the direction deflecting at a prescribed angle to the direction toward a position of the top peripheral wall disposed in the gas duct, from a center of the gas reforming furnace, and swirl flow is formed in the gas reforming furnace.
