FLUIDIZED BED COMBUSTION METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a combustion method and a fluidized bed type combustion device for the combustion method in which either liquid or slurry fuel can be ignited continuously and stably at a fluidized bed. SOLUTION: A funnel-shaped fluidized material mixing chamber 21 is fixed to a side part of a fluidized bed type combustion furnace 1 at an inclination angleθ(40 deg. to 50 deg.). A burner gun 20 is similarly fixed to the upper end part of the mixing chamber 21 while being inclined thereto. This burner gun 20 is of a double structure, wherein a cylindrical fuel supplying pipe 7 is installed inside and a cylindrical fluidized material pipe 18 to which a fluidized material 13 and infection air 17 for the fuel are supplied is installed outside and at the same time the extremity end of the fluidized material supplying pipe 18 is provided with a funnel-shaped fluidized material mixing pipe 19.
