TECHNOLOGICAL VORTEX EJECTION GAS BURNER Russian patent published in 2012 - IPC F23D14/62 

FIELD: power industry.

SUBSTANCE: technological vortex ejection gas burner includes nozzle and mixer including convergent, divergent sections and a neck; and in addition, it includes end plate connected to ring and cylindrical section, with holes made in it, which are uniformly distributed along concentric circles about nozzle axis and acting as the first ejection stage. Burner has the second ejection stage made in the form of scavenging opening representing a system of tangential channels separated with guide vanes. Scavenging opening is located between external surface of mixer neck and internal surface of divergent section and formed by offsetting the outlet section of the neck towards convergent section of mixer.

EFFECT: improving the quality of mixture formation, complete fuel combustion; shortening mixer length; increasing specific power; enlarging the range of stable operation as to excess air coefficient; improving cooling efficiency of neck and divergent section of mixer.
