Abstract

The invention relates to an apparatus for fuel injection in a turbine engine. In one embodiment, a system includes a fuel injector including a liquid fuel passage extending to a first port in a tip portion. The fuel injector also includes a selectable flow passage extending to a second port in the tip portion. The selectable flow passage surrounds the liquid fuel passage to the tip portion, the selectable flow passage is configured to selectively receive a gas fuel flow and an air flow, and the selectable flow passage has a flow temperature configured to cool a liquid fuel flowing through the liquid fuel passage to reduce coking.

Description

technical field [0001] The subject matter disclosed herein relates to gas turbine engines, and more particularly, to fuel nozzles. Background technique [0002] A gas turbine engine includes one or more combustors that receive and combust compressed air and fuel to produce hot combustion gases. For example, a gas turbine engine may include a plurality of combustors positioned circumferentially about an axis of rotation. The combustor may inject liquid fuel, gaseous fuel, or a combination of the two fuels via fuel injectors positioned at the base of the combustor. Unfortunately, due to the high temperatures associated with combustion, liquid fuel may undergo coking before exiting the fuel injector. Coking is the condition in which fuel begins to crack to form carbon particles. These particles can become attached to the interior walls of the liquid fuel injector. Over time, the particles can break free from the walls and clog the tip of the liquid fuel injector, interferin...
