効果を有するものである。The present invention is a double rotary burner in which a rotary combustion device B is connected to a burner A. The combustion device B is a flammable or flame-retardant industrial waste which is usually used for fuel. Incineration methods include pulverized materials such as plastics, wood, and mixtures thereof, which are difficult to treat due to environmental destruction due to lack of heat and the generation of foul-smelling odors. Using burnt coal etc. as fuel, complete combustion using high temperature and high pressure complete combustion gas generated by the operation of burner A as a heat source, and obtaining a burner that generates high energy complete combustion gas without ultra-high temperature, soot and odor, It has an excellent effect on the incineration of industrial waste.
