摘要： A nozzle assembly (10) comprises a first-fuel-inlet tube (80), a second-fuel-inlet tube (90), and a plate stack (100). The nozzle-plate stack (100) defines a central circuit (104), corner air circuits (105), a first fuel circuit (106) and a second fuel circuit (107). The fuel circuits (106, 107) include a swirl chamber in which the fuel is swirled prior to being merged with the central circuit (104). The corner air circuits (105) merge with the central circuit (104) downstream of the fuel circuits' merge and provide an additional swirling component to further shape the fuel-air stream prior to ignition.

摘要： Provided is an injector having a plurality of micro-mixing nozzles having axes thereof pointing radially inwardly or outwardly with respect to a main axis of the injector and a plurality of micro-mixing nozzles having axes thereof extending axially with respect to the main axis of the injector. The arrangement of micro-mixing nozzles provides a means for fast and efficient mixing of fuels, such as highly reactive fuels including hydrogen. The arrangement of micro-mixing nozzles also achieves low NOx emissions.

摘要： An injector assembly includes a barrel-shaped housing and an injector, the injector including a feed ring formed of multiple, etched, T-shaped plates. A plurality of nozzles are arranged in an evenly-spaced array around the injector and direct fluid radially inward into the central annulus of the injector assembly. The injector includes an air inlet port with an internal feed passage fluidly connected to swirl chambers and exit orifices to provide individual sprays of fuel from the nozzles. Integral air swirlers impart a swirling component of motion to the fuel sprays. A venturi configuration is provided by the housing. The nozzles are provided along the venturi configuration, which maintains fluid separation from the walls of the housing downstream from the venturi.

摘要： A fuel nozzle for dispensing an atomized fluid spray into the combustion chamber of a gas turbine engine. The nozzle includes a body assembly with an inner fuel passage and an annular outer atomizing air passage. The inner fuel passage extends axially along a longitudinal axis to a first terminal end defining a first discharge orifice of the nozzle. The outer air passage extends coaxially with the inner fuel passage along the longitudinal axis to a second terminal end disposed concentrically with the first terminal end and defining a second discharge orifice oriented such that the discharge therefrom impinges on the fuel discharge from the first discharge orifice. An array of turning vanes is disposed within the outer air passage in a circular locus about the longitudinal axis. Each of the vanes is configured generally in the shape of an airfoil and has a pressure side and an opposing suction side. The vanes extend axially from a leading edge surface to a tapering trailing edge surface along a corresponding array of chordal axes, each of axes is disposed at a given turning angle to the longitudinal axis. The suction side of each vane is spaced-apart from a juxtaposing pressure side of an adjacent vane to define a corresponding one of a plurality of aligned air flow channels therebetween. Atomizing air is directed through the air flow channels to be issued from the second discharge orifice as a generally helical flow having a substantial uniform velocity profile.

摘要： A fuel injector for a gas turbine engine has an inlet fitting, a fuel nozzle, and a housing stem with a pair of fuel conduits fluidly interconnecting the nozzle and fitting. The fuel nozzle includes an annular secondary fuel passageway directing fuel from one fuel conduit to an annular discharge orifice at a discharge end of the nozzle. The secondary fuel passageway is defined between an outer, annular fuel conduit portion and a primary adapter. The primary adapter has an outer surface with a distinct, radially-outwardly-projecting annular shoulder to restrict flow through the secondary passageway and provide substantially uniform distribution of flow through the passageway downstream of the shoulder, for improved combustion and flame stability.
