    摘要: An apparatus is disclosed for injecting fluid coolant into a gas turbine engine combustion system at a location distal the fuel nozzle, such as at the primary or dilution orifices of the combustor. In one embodiment of the invention, the apparatus comprises a substantially hollow cylindrical tube adapted for insertion into a primary jet orifice of the combustor. A water nozzle is housed at the end of the tube opposite the primary jet orifice. The water nozzle is positionally adjustable relative to the inner liner. A pair of apertures is disposed along the tube between the primary jet orifice and the water nozzle so as to admit primary jet air from the plenum surrounding the combustion chamber into the tube. The apertures are configured to impart a swirling motion to the primary jet air as it enters the tube. Alternatively, at least one baffle may be housed within the tube proximal the aperture to impart a swirling motion to fluid communicated to the tube by the plenum. The water nozzle mixes water with the swirling air in the tube prior to the swirling air being admitted into the combustor through the primary air jet orifice. By pre-mixing the water with primary air, the need for complicated water/fuel injectors is obviated and the problems associated with injecting water proximal the fuel injector are eliminated.

    摘要: An axial flow fuel nozzle for a gas turbine includes a plurality of annular passages for delivering materials for combustion. An annular air passage receives compressor discharge air, and a plurality of swirler vane slots are positioned adjacent an axial end of the annular air passage. A first next annular passage is disposed radially inward of the annular air passage and includes first openings positioned adjacent an axial end of the first annular passage and downstream of the swirler vane slots. A second next annular passage is disposed radially inward of the first annular passage and includes second openings positioned adjacent an axial end of the second annular passage and downstream of the first openings.

    摘要: A fuel nozzle configured to channel fluid toward a combustion chamber within a gas turbine engine and a method for assembling the same are provided. The fuel nozzle includes a first hollow tube fabricated from a first material that has a first coefficient of thermal expansion and a second tube fabricated from a second material that has a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. The second tube is coupled within the first tube such that the first tube substantially circumscribes the second tube, and the second tube thermally expands approximately at a same rate as the first tube during fuel nozzle operation.

    摘要: An annular combustor having fuel preparation chambers mounted in the dome of the combustor. The fuel preparation chamber comprises an annular wall extending axially from an inlet to an exit that defines a mixing chamber. Mounted to the inlet are an air swirler and a fuel atomizer. The air swirler provides swirled air to the mixing chamber while the atomizer provides a fuel spray. On the downstream side of the exit, the fuel preparation chamber has an inwardly extending conical wall that compresses the swirling mixture of fuel and air exiting the mixing chamber.
