Abstract:
A fuel nozzle (50) for a gas turbine engine, including a first injection circuit (82) including an annular discharge opening (94), the first injection circuit for injecting liquid fuel downstream from the nozzle into the gas turbine engine; a second injection circuit (84) aligned substantially concentrically with respect to the first injection circuit; and a third injection circuit (86) aligned substantially concentrically with respect to the first injection circuit, the second injection circuit is between the second and third injection circuits, one of the second and third injection circuits for injecting water downstream from the nozzle into the gas turbine engine, one of the second injection circuit and the third injection circuit comprising an annular discharge opening (132).
Abstract:
A method facilitates fabricating a gas turbine engine swirler assembly (30). The method comprises coupling a (36) venturi to a primary swirler (32), and coupling the venturi to a secondary swirler (34) such that a gap (120) is defined between a portion of the venturi and a portion of one of the primary swirler and the secondary swirler.
