Claims

[Scope of utility model registration request]

A suction pipe that receives gas fuel injection from a fuel nozzle and sucks combustion air together with the gas fuel, and a mixture forming device that connects to this suction pipe to form a mixture of gas fuel and combustion air and guide it to the combustion section. The burner consists of a main burner and an auxiliary burner, each having its own flame port made of a heat-resistant wire mesh for introducing the mixture from the mixture forming part and combusting it.
A secondary burner that includes a cylindrical flame port for the main burner and a hemispherical flame port for the secondary burner, inside a cylindrical outer cylinder made of heat-resistant metal with an open bottom end that constitutes the air-fuel mixture forming part of the main burner. The flame port of the auxiliary burner is a channel portion having a ring-shaped channel with an open lower part, which is protruded like a flange from the outer periphery of the open end side of the mixture forming portion of the auxiliary burner. and a channel-shaped retaining ring fitted into the channel of the channel portion, and the upper end edges of the channel portion are held between the inner flange portions of the channel portion and the inner flange portion of the retaining ring, and the upper end edges of the channel portion and the retaining ring are sandwiched in the horizontal direction by the web portions of the channel portion and the retaining ring. A gas burner characterized by:
