Abstract (en)

[origin: JPH0233505A] PURPOSE: To perform clean combustion, to reduce a rate of the generation of nitrogen oxide to a slight value, and to prevent the generation of an unburnt hydrogen carbide during starting and a stop, by a method wherein a stationary mixing head having an opening for a combustible gas mixture is positioned at the outlet of a gasifying device. CONSTITUTION: A unit 27 comprises a gasifying device 17 a mixing head 29 an air aperture plate 35, and an electric heater 39. The mixing head 29 and the gasifying device 17 consists of integral parts, and a deflector part 31 is provided. The unit 27 is surrounded with a flame tube 21. A space 40 between the gasifying device 17 and the flame tube 21 forms a recirculation passage for high temperature combustion gas to an inlet 41. A hollow rotary body consists of the gasifying device 17 and the mixing head 29, and the front part thereof is formed in a form of a single cylindrical tube part 30 closed by a disc 31. The disc 31 is operated as a deflector part from a gas mixture, and the gas mixture flows out through the outlet opening 33 having a plurality of slots. The outlet opening 33 is positioned at a tubular part 36 of the mixing head and gas substantially radially flows out from the mixing head 29.
