Claims

[Scope of utility model registration request]

A gas burner pad is arranged in a cylindrical shape on a ring header that supplies fuel gas via a spud base,
In a gas burner such as a gas-fired boiler in which a gas nozzle for injecting fuel gas obliquely to the spud axis is provided at the tip of the gas burner spud and the outer periphery is covered with a protective tube for cooling the gas spud, the connection between the base of the spud and the gas burner spud is A gas burner characterized in that a spud spin angle adjustment mechanism for adjusting the gas nozzle surface by rotating the gas burner spud together with a gas spud cooling protective tube is provided in between.
