Abstract
A fuel nozzle assembly having an inlet region of a fuel nozzle base assembly that provides more uniform flow of fuel within the fuel nozzle assembly. The embodiments described herein provide fuel flow conditioning components that manage fuel uniformity within a fuel annulus and make more efficient use of allocated space, thereby overcoming spatial constraints imposed on the overall fuel nozzle assembly.
Claims20
A fuel nozzle assembly comprising:
- an end cover configured to receive a fuel;
- a fuel channel defined by the end cover and configured to route the fuel through a portion of the end cover;
- a fuel nozzle base assembly having a fuel nozzle inlet region, the fuel nozzle base assembly being located adjacent to, and operatively coupled to, the end cover;
- an orifice plate disposed between the end cover and the fuel nozzle base assembly, the orifice plate having a plurality of apertures extending therethrough;
- and
- an annular fuel plenum at least partially defined by the end cover and the orifice plate.
3 more elements
A fuel nozzle assembly comprising:
- a fuel nozzle base assembly having a main fuel inlet;
- a fuel manifold at least partially defined by the fuel nozzle base assembly, the fuel manifold configured to receive a fuel provided through the main fuel inlet;
- and
- a plurality of fuel passages circumferentially spaced from each other and extending from the fuel manifold to a fuel annulus.
1 more element
A fuel nozzle assembly comprising:
- a fuel nozzle base assembly configured to receive a fuel therein;
- an fuel annulus defined at an upstream end of the fuel nozzle base assembly;
- and
- a pre-orifice structure directly coupled to the fuel nozzle base assembly and configured to route the fuel to the fuel annulus therein.
