Abstract (en)
[origin: EP0939275A2] A fuel nozzle/guide assembly for a gas turbine engine for reducing NOx emissions has a central axial inflow swirler (32) and either three concentric radial inflow swirlers (34, 62, 88) or, alternatively, two concentric radial inflow swirlers (34, 62) and a concentric array of air passages (74), for rapid uniform fuel-air mixing downstream from the fuel injector. <IMAGE>
