摘要： A combustor fuel nozzle includes a center body and an inner shroud that circumferentially surrounds at least a portion of the center body. The inner shroud has a downstream surface. The fuel nozzle includes an inner passage between the center body and the inner shroud, an outer passage that circumferentially surrounds at least a portion of the inner shroud and a first plurality of fuel ports extending substantially radially outward through the center body. The first plurality of fuel ports is upstream from the downstream surface of the inner shroud. A method for supplying fuel to a combustor fuel nozzle includes flowing a working fluid through an inner passage between a center body and an inner shroud, injecting a fuel from the center body against the inner shroud, and flowing a portion of the working fluid through an outer passage that surrounds at least a portion of the inner shroud.

摘要： A fuel distribution manifold comprises an outer shell having an inner surface. The outer shell defines an inlet for receiving fuel from a parent supply line, a base opposite the inlet, a central manifold axis that intersects the inlet, and a plurality of outlets for delivering fuel to offspring fuel lines, each outlet defining a respective outlet axis. In one exemplary embodiment, a fuel distribution manifold also comprises a center-body having an outer surface and being positioned within the outer shell wherein the outer surface of the center-body and the inner surface of the outer shell define a flow-path through which fluid flows from the inlet to the plurality of outlets. In another exemplary embodiment, at least one of the outlets is positioned adjacent to the base and oriented so that its respective outlet axis is rotated relatively to a radial direction that intersects the central manifold axis.

摘要： A combustor includes an end cap having upstream and downstream surfaces and a cap shield surrounding the upstream and downstream surfaces. First and second sets of premixer tubes extend from the upstream surface through the downstream surface. A first fuel conduit supplies fuel to the first set of premixer tubes. A casing circumferentially surrounds the cap shield to define an annular passage, and a second fuel conduit supplies fuel through the annular passage to the second set of premixer tubes. A method for supplying fuel to a combustor includes flowing a working fluid through first and second sets of premixer tubes, flowing a first fuel into the first set of premixer tubes, and flowing a second fuel through an annular passage surrounding the end cap and into the second set of premixer tubes.
