<P>PROBLEM TO BE SOLVED: To provide a gas burner capable of improving combustion stability during low load combustion and durability. <P>SOLUTION: The gas burner 1 includes a combustion cylinder 4 allowing the passage of combustion air A and a burner nozzle 2 arranged in the combustion cylinder 4 and allowing the passage of a fuel gas F. All around the distal end of the burner nozzle 2, a flange 21 is provided which projects to the outer peripheral side in a radial direction. At the distal end face 211 of the flange 21, a plate 3 is provided which blocks the opening distal end 22 of the burner nozzle 2. In the plate 3, a gas blow-off port 31 is formed which blows off the fuel gas F to the outer peripheral side in the radial direction. In the flange 21, an air blow-off port 23 which blows off the fuel air A to the distal end side in an axial direction is formed around the plate 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
