Abstract
A fuel nozzle for a combustor includes a fuel body, a primary fuel passage having a primary fuel outlet, and a secondary fuel passage having a secondary fuel outlet, the secondary fuel passage being non-concentric with the primary fuel passage. The primary fuel outlet and the secondary fuel outlet are non-parallel. An axial centerline of the primary fuel outlet is angled with respect to an axial centerline of the primary fuel passage and an axial centerline of the secondary fuel outlet is colinear with an axial centerline of the secondary fuel passage. Also provided is a method of introducing non-concentric, non-parallel fuel flows to a combustor is also provided.

A fuel nozzle for a combustor, the fuel nozzle comprising:
- a fuel nozzle body;
- a primary fuel passage having a primary fuel outlet;
- and
- a secondary fuel passage having a secondary fuel outlet, the secondary fuel passage being non-concentric with the primary fuel passage,
- wherein the primary fuel outlet and the secondary fuel outlet are non-parallel,
- wherein an axial centerline of the primary fuel outlet is angled with respect to the fuel nozzle body and an axial centerline of the secondary fuel outlet is colinear with the fuel nozzle body, and
- wherein the primary fuel outlet is a single orifice and the only outlet of the primary fuel passage, and the secondary fuel outlet is a single orifice and the only outlet of the secondary fuel passage.
A method of introducing fuel into a combustor, the method comprising:
- introducing a primary fuel flow through a primary fuel passage in a circumferential direction with respect to the combustor;
- and
- introducing a secondary fuel flow through a secondary fuel passage in a radially inward direction with respect to the combustor,
- wherein the primary fuel flow is non-concentric with the secondary fuel flow and non-parallel with the secondary fuel flow, and
- wherein the primary fuel flow and the secondary fuel flow are introduced from a single fuel nozzle.
