Abstract

The present invention reduces straightness of jet flame and adjusts the flame length to realize optimum furnace temperature distribution. The burner comprises a primary air passage 14 through which a primary air belches inside the furnace, a secondary air passage 16 thorough which a secondary air belches inside the furnace, a fuel supply pipe 28 which is disposed in the primary air passage 14 and though which a fuel gas belches inside the furnace and a flame stabilizing member 30 disposed at the distal end of the fuel supply pipe 28. At the tip of the fuel supply pipe 28 is disposed a diffusion chip 29 for allowing the fuel gas to diffuse toward the primary air belching inside the furnace from the primary air passage 14.
