  • Patent number: 8640463
    Abstract: A swirler for fuel injection in a gas turbine engine includes a frustoconical swirler body. A first and a second air flow path direct air in generally opposed circumferential directions into the swirler. These air paths intermix and create turbulence. As this turbulence encounters fuel droplets, the fuel is atomized, and uniformly distributed within the air flow. A shear layer is created adjacent an inner surface of the swirler body. In a separate feature, a third air flow path is directed into the air.

  • Patent number: 5240404
    Abstract: An industrial gas burner is disclosed which operates at low air/fuel ratios to avoid NO.sub.x formation without carbon sooting. The burner includes a refractory block having a cylindrically stepped throat passage extending therethrough, a housing adjacent the inlet end of the refractory block and a swirl plate inbetween the block and housing. Vane passages in the swirl plate provide fluid communication between the throat passage and an annular entrainment passage in the housing. A plurality of circumferentially spaced gas jet nozzles in the entrainment passage cause jet entrainment and mixing of fuel and combustion air which is ported to the entrainment chamber. The jet streams of mixed air/fuel impinge the swirl plate whereat the mixture undergoes a further mixing because of the pressure drop and swirling therein. The swirling air/fuel mixture is thus intimately and thoroughly mixed when it exits the swirl plate as a swirling mass at the entry end of the throat passage where it is ignited.
