PROBLEM TO BE SOLVED: To suppress the exhaust of nitrogen oxide, suppress the treatment stagnation of waste and suppress wasteful consumption of combustion improver by inhibiting misfire in a combustion chamber when a waste incinerating device using a swirl type melting furnace performs low-air-ratio combustion. SOLUTION: In a main combustion chamber 13 of the melting furnace for combustion melting in environment of an air ratio being 1.0 or lower, a main combustion chamber burner 61 and a pilot burner 74 are provided for supplying seed flames to the main combustion chamber 13 and for assisting the main combustion chamber burner 61, respectively. The pilot burner 74 is kept in combustion at all times during the combustion operation of waste. COPYRIGHT: (C)2008,JPO&INPIT
