Abstract: A fuel injector 28 for gaseous and liquid fuel is disclosed. Various construction details are developed to enhance mixing and reduce nitrogen oxide emissions in a compact design. In one embodiment of the invention, the fuel nozzle 28 includes two radially spaced passages 68, 104 for air having swirlers 86, 112 and a liquid fuel passage 57 disposed between the air passages and a gaseous fuel passage 116 outwardly of the outermost air passage. In one detailed embodiment, a center body 76 is disposed in the inner air chamber to promote re-ciruclation of the hot gases.

Abstract: A premix liquid fuel nozzle has longitudinal air entrance slots (24) into a cylindrical chamber (20). A centerbody (42) produces an axially increasing flow area toward the chamber outlet (32). Liquid fuel is atomized in a specified location (58) adjacent the co nical centerbody (42). This area has a high axial shear velocity producing thoroug h vaporization and uniform mixing before combustion.
