Abstract
A combustor section is provided and includes a segmented annular manifold mounted upstream from a fuel nozzle support in a section of a passage through which an oxidizer flows, each segment of the manifold being substantially axially aligned and including a body to accommodate fuel internally that is formed to define injection holes through which the fuel is injected into the passage through which the oxidizer flows upstream of the fuel nozzle support.
Claims29
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.

A combustor section, comprising:
- a casing;
- a cap assembly, having a fuel nozzle support formed therein, the cap assembly being disposed within the casing to define an annular passage between the casing and the cap assembly through which oxidizer flows in a reverse direction, then in a radially inward direction and then in a forward direction opposite the reverse direction upstream from the fuel nozzle support;
- and
- a segmented annular quaternary fuel manifold mounted within a section of the passage at which the oxidizer flows in the reverse direction, the segmented annular manifold being mounted at a location defined axially upstream from the fuel nozzle support relative to a combustor centerline axis, each of the segments being substantially axially aligned with one another and including a body in which fuel is accommodated and injection holes through which the fuel is injected into the passage section.

An annular fuel manifold of a combustor, the combustor including a casing;
- and a cap assembly disposed within the casing to define an annular passage through which oxidizer flows in a reverse direction, then in a radially inward direction and then in a forward direction opposite the reverse direction upstream from a fuel nozzle support, the annular fuel manifold comprising:
- a segmented annular body, each body segment being substantially axially aligned with one another, formed to accommodate fuel therein, and formed to define fuel injection holes by which the fuel is injected into a section of the passage at which the oxidizer flows in the reverse direction at a location defined axially upstream from the fuel nozzle support relative to a combustor centerline axis.
A combustor section, comprising:
- a segmented manifold configured for quaternary fuel injection into a combustor, the segmented manifold being mounted at a location defined axially upstream from a fuel nozzle support relative to a combustor centerline axis 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
- each segment of the manifold being substantially axially aligned with one another and including a body to accommodate fuel internally,
- the bodies together defining the segmented manifold having a shape similar to a shape of the passage section at an axial location of the body and wherein each body is 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.
