Abstract

A fuel injector (60) for a combustor presented either as a simplex or duplex pressurized fuel injector, wherein the fuel is introduced into the injector to provide a swirl to the fuel in a first annular channel (68) which communicates with a coaxial conical fuel swirl chamber (70) and then the primary nozzle. In a duplex version, a secondary annular swirl channel (76) is provided for spinning the fuel and communicating downstream with a conical fuel swirl chamber (82) and eventually an annular nozzle (84) whereby the fuel is atomized as it exits the nozzle. An air swirler (66) is also provided with the fuel injector (60), and the air swirler (66) includes air passages (90) arranged in an annular array about the fuel injector tip (64). A second array of auxiliary air passages (92) can be arranged spaced radially from the first array (90) and also to provide an air swirl and to control the spray cone of the fuel air mixture.
