Abstract (en)

[origin: WO9855800A1] A dual fuel premix injector (22, 222) for injecting liquid and/or gaseous fuel into a gas turbine engine (20) is designed to minimize emissions and contamination. The dual fuel premix injector (22, 222) includes a fuel-air mixing chamber (90, 290) bounded by an injector outer wall (83, 283). A plurality of inwardly-directed fuel atomizers (82, 126, 282) are mounted to the inner surface of the outer wall (83, 283) for introducing liquid fuel into the fuel-air mixing chamber (90, 290). The fuel atomizers (82, 126, 282) may be either air-blast atomizers (82, 282) or tubular atomizers (126).
