Abstract:
A fuel injector for a gas turbine engine is disclosed. The fuel injector includes two primary tubes, a secondary tube, a primary gas gallery, and a secondary gas gallery. The two primary tubes are connected in a parallel configuration to provide a main gas fuel to the primary gas gallery. The secondary tube provides the main gas fuel to the secondary gas gallery independent from the two primary tubes and the primary gas gallery. The primary gas gallery and the secondary gas gallery provide the main gas fuel to a premix passage independently allowing for robust control of the gas turbine engine.
