Claims

[Scope of utility model registration request]

A cylindrical nozzle 1 is provided in which a combustion air jet flow path R ₁ and a fuel gas jet flow path R ₂ facing the combustion space are arranged substantially concentrically, and one of the two jet flow paths R ₁ and R ₂ is provided. A distribution chamber A is connected to the end of the cylindrical nozzle 1, and the distribution chamber A is connected to the other of the jetting channels R ₁ and R ₂ .
provided over the entire outer circumference of the cylindrical nozzle 1,
The jetting channels R ₁ and R ₂ are arranged around the distribution chamber A. A burner is connected to a supply pipe 4 directed toward the center of the burner, and the gas entering from the supply pipe 4 makes a U-turn to the upper side of the jet flow path R ₁ or R ₂ to form the jet flow path R _{1 .} Alternatively, a cylindrical guide 5 forming a U-turn flow path R ₃ that enters R ₂ is provided in the distribution chamber A over the entire circumference of the jet flow path R ₂ , and the axis of the cylindrical guide 5 is A burner in which the cylindrical guide 5 is arranged with respect to the distribution chamber A so that P is eccentric toward the supply pipe 4 side with respect to the axis O of the distribution chamber A.
