GAS BURNER Russian patent published in 2006 - IPC F23D14/38 

FIELD: heat power engineering.

SUBSTANCE: gas burner comprises housing, mixer that is coaxially mounted inside the housing to define ring space, connected to the space through radial openings, and provided with the air nozzle at its exit, and ring collector that is provided with the rows of radial openings, abuts against the exit section of the mixer, defines the outlet passage, and is connected with the fuel source. The outlet passage is provided with the perforated converging nozzle at its exit, and insert provided with the central and axial passages at its outlet. The insert has injection system arranged together with the axial passages around the central passage at an angle to the axis of the burner and provided with the injecting and mixing passages separated by the ring bore which is connected with the outlet passage. The central passage receives the inlet nozzle that defines the ring space for connecting the outlet passage with the ring bore. The nozzle is secured to the outlet section of the mixer to define intermediate space connected with the mixer through radial openings made in the wall of the outlet nozzle. The axial passages together with the injection system connect the outlet passage with the mixer or intermediate space.

EFFECT: enhanced efficiency.
