ABSTRACT:
High temperature deterioration of an injector 34 for a gas turbine including a compressor and a turbine wheel 10, 14, 30 is avoided through the use of swirler blades 60 that form a forced vortex adjacent the ends 52, 58 of fuel and oxidant injection tubes 38, 40 to prevent separation of the mixed stream thereby eliminating backflows or eddies of burning fuel.
