FUEL NOZZLE ASSEMBLY

摘要

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.

主权项

1. 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.
