High-hydrogen fuel gas burner

The utility model discloses a high-hydrogen fuel gas burner and relates to burners. A main burning gun (2) is arranged in a burner shell (7); a main burning gun fuel inlet (10) is formed on the lower part of the main burning gun; a main burning gun spraying head (12) is arranged on the upper part of the main burning gun; one side of the main burning gun is provided with an incandescent light (5); the lower part of the incandescent light is provided with an incandescent light fuel inlet (11); the upper part of the incandescent light is provided with an incandescent light spraying head (18); a brazier brick (1) is arranged on a brazier brick supporting plate (24); an outer noise reduction layer (3) is arranged on the inner wall of the burner shell; a burner bottom plate (19) is arranged on the lower part of the burner shell; and an air distribution system is arranged at the middle-lower part of the burner shell. The high-hydrogen fuel gas burner can short a mixing process of fuel gas and air in the burner; an air inlet rotational flow is weakened; the mixing of the fuel gas and the air can be delayed; the main burning gun is arranged for delaying the burning process; the flame length is lengthened; and a flame stabilizing cover rotational flow hole is formed to stabilize a flame so that the flame can be burned rigidly.
