FIELD: burners for combustion of gas. ^ SUBSTANCE: gas burner comprises air duct with a nozzle, gas duct coaxially mounted inside the air duct, and conical mixer. The end part of the air duct is provided with a row of openings uniformly arranged over the air duct at an acute angle to the axis of the burner. The axis of the opening is directed to the toroidal groove in the inner cylindrical surface of the nozzle. The gas duct is provided with a head with at least six ports which are eccentrically and uniformly arranged with respect to the axis of the burner at an acute angle to the axis of the burner. The ports in the air duct are inclined at an angle of 30-60o to the burner axis. The ports in the gas duct are inclined to the axis of the burner at an acute angle of 30-60o. ^ EFFECT: enhanced stability of combustion and efficiency. ^ 2 cl, 3 dwg |
