PROBLEM TO BE SOLVED: To provide a gun type burner capable of providing excellent combustion by utilizing swirl flow by two inner and outer stabilizers in fine diffusion and mixing. SOLUTION: This gun type burner comprises a burner inner tube 18 having a plurality of air holes formed in the peripheral wall thereof. The burner inner tube 18 is formed in a two stage shape formed of a small diameter combustion tube 19 connected to a straightening tube 4 so as to surround the primary stabilizer 15 and a large diameter combustion tube 20 connected to the tip of the small diameter combustion tube 19. The secondary stabilizer 22 is installed on the outer periphery of a connection part between the tip of the small diameter combustion tube 19 and the large diameter combustion tube 20. A laminar flow jetting part 23 jetting tertiary laminar flow air with the same diameter as that of the small diameter combustion tube 19 is formed between the secondary stabilizer 22 and the tip of the small diameter combustion tube 19. By this, since swirl flows are not interfered with each other in the large diameter combustion tube 20, excellent combustion can be provided by fine diffusion and mixing. COPYRIGHT: (C)2005,JPO&NCIPI
