Abstract
A fuel distributor is disclosed comprising a body having a unitary construction, a fuel conduit located within the body, a fuel flow path located within the body that is oriented in a circumferential direction around an axis and in flow communication with the fuel conduit, and at least one orifice located in the body in flow communication with the fuel flow path such that a fuel entering the fuel conduit exits through the orifice.
Claims21
A combustor component comprising:
- a body having a unitary construction;
- a fuel conduit located within the body that is oriented in a substantially axial direction;
- a fuel flow path located within the body that is oriented in a circumferential direction around an axis and in flow communication with the fuel conduit;
- and
- at least one orifice located in the body in flow communication with the fuel flow path such that a fuel entering the fuel conduit exits through the orifice.

A fuel distributor comprising:
- a body having a unitary construction;
- a plurality of fuel conduits located within the body oriented in a substantially axial direction and having a substantially constant flow area;
- a plurality of fuel flow paths located within the body oriented in a circumferential direction around an axis in flow communication with at least one of the fuel conduits and having a flow area that varies in the circumferential direction;
- and
- a plurality of orifices located in the body in flow communication with at least one of the plurality of fuel flow paths arranged circumferentially around the axis such that a fuel entering the fuel conduits exits through the orifices.
2 more elements
A fuel nozzle 5 comprising:
- an annular fuel distributor having a unitary construction and having at least one fuel conduit oriented in a substantially axial direction within a body and having at least one fuel flow path within the body in flow communication with the fuel conduit and oriented in a circumferential direction around an axis;
- an annular air swirler located radially inside the unitary fuel distributor capable of swirling an air stream entering the air swirler;
- and
- a fuel injector located radially inside the annular air swirler capable of injecting a stream of fuel into a mixing chamber such that the fuel and air are mixed within the mixing chamber.
1 more element
An air swirler comprising:
- an annular body;
- a row of outer vanes located on the annular body arranged circumferentially around an axis;
- a row of inner vanes located on the annular body arranged circumferentially around the axis and located radially inner to the row of outer vanes;
- and
- an annular splitter located on the body, wherein the annular body, the row of outer vanes, the row of inner vanes and the annular splitter have a unitary construction.
