ABSTRACT:
In a burner nozzle for heating, flame cleaning, gas cutting, etc., where oxygen and fuel gas are mixed near the nozzle orifice, at least two expansion steps are provided for the oxygen, the last expansion step being connected by jet passages to nozzle discharge channels which intersect closed-ended fuel channels lying in the same imagined cylindrical or conical body, the intersections each occurring between the jet passage and the nozzle orifice of the discharge channel to form a relatively large mixing space determined by the depth and width of the channels and the angle between the channels. The closed-ended portion of each fuel channel beyond the intersection forms a resonator chamber for the gas. The nozzle provides good mixing and safety properties. The channels are formed as slots on the surface of an inner member, the slots being closed by an encompassing outer member.
