CPC F23R 3/286 (2013.01) | 16 Claims |
1. A combustor for a turbine engine, the combustor comprising:
a fuel injector having a mixer assembly with a pilot mixer and a main mixer, the fuel injector injecting fuel through the pilot mixer to generate a pilot fuel stream and through the main mixer to generate a main fuel stream;
a fluid injection system in fluid communication with the combustor, the fluid injection system injecting a fluid into the combustor; and
a controller that is communicatively coupled to the fuel injector and the fluid injection system, wherein the controller:
controls the fuel injector to inject the pilot fuel stream through the pilot mixer and the main fuel stream through the main mixer during a high power operation of the turbine engine;
controls the fluid injection system to inject the fluid into the combustor during the high power operation; and
controls the fluid injection system to shut off the fluid into the combustor during an entirety of a low power operation of the turbine engine and during an entirety of a mid-level power operation of the turbine engine,
wherein the low power operation is less than 30% of a maximum rated thrust of the turbine engine, the mid-level power operation is 30% to 85% of the maximum rated thrust of the turbine engine, and the high power operation is greater than 85% of the maximum rated thrust of the turbine engine.
