Low emission combustion nozzle for use with a gas turbine engine
An injector nozzle having a central axis, the injector nozzle is described comprising; a generally cylindrical outer casing being coaxially positioned about the central axis and having a first end, a second end and a wall defining an inner surface and an outer surface, the wall further defining an aperture therein extending between the inner surface and the outer surface and positioned near the first end; an outer tubular member having a passage therein and being positioned in the aperture and attached to the casing; a plate positioned at the first end and being attached to the casing, the plate having a plurality of secondary passages therein; an inner member being coaxially positioned about the central axis within the outer casing and including a main body having a first end attached to the plate, a second end and an external stepped surface, an end cap having a first end attached to the second end of the main body, a second end and a concave inner surface, and a generally cylindrical shell coaxially positioned about the central axis, having a first end attached to the external stepped surface intermediate the first and second ends thereof, a second end and a plurality of holes being radially positioned and evenly spaced about the shell; means for passing a pilot fuel through the injector nozzle during operation thereof, means for introducing a supply of pilot air through the injector nozzle, the supply of pilot air being mixed with the pilot fuel only after exiting the injector nozzle during operation thereof; means for introducing a primary supply of air through the injector nozzle during operation thereof, the means for introducing the primary supply of air including a main air passage being defined by a portion of the inner surface of the wall and a portion of the shell; and means of passing a main source of fuel through the injector nozzle during operation thereof.
