Patent ID: 8418468

Claim:
A combustor section, comprising: a segmented annular quaternary fuel manifold mounted at a location defined axially upstream from a fuel nozzle support relative to a combustor centerline axis, the segmented annular manifold being mounted in a section of a passage through which an oxidizer flows, the passage being defined such that the oxidizer flows through the passage in a reverse direction radially outwardly of the fuel nozzle support and in a forward direction radially aligned with the fuel nozzle support, the segmented annular manifold being located in a section of the passage in which the oxidizer flows in the reverse direction at a local velocity that exceeds oxidizer flow velocities in other sections of the passage, each segment of the manifold being substantially axially aligned with one another and including a body to accommodate fuel internally, the body being formed to define injection holes through which the fuel is injected into the passage through which the oxidizer flows, the fuel injection occurring axially upstream of the fuel nozzle support.
