Abstract
A combustor for a turbine engine. The combustor includes a fuel injector and a fluid injection system in fluid communication with the combustor. The fuel injector includes a mixer assembly with a pilot mixer and a main mixer. The pilot mixer and the main mixer operate during high power operation of the turbine engine. The fluid injection system injects a fluid into the combustor during high power operation of the turbine engine. The fluid is shut off during low power operation of the turbine engine and during mid-level power operation of the turbine engine.

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 pilot mixer and the main mixer operating during a high power operation of the turbine engine;
- and
- a fluid injection system in fluid communication with the combustor, the fluid injection system injecting a fluid into the combustor during the high power operation of the turbine engine,
- wherein the fluid is shut off during a low power operation of the turbine engine and during a mid-level power operation of the turbine engine.
A method of operating a combustor for a turbine engine, the method comprising:
- operating a pilot mixer and a main mixer of a mixer assembly of the combustor during a high power operation of the turbine engine;
- injecting a fluid into the combustor during the high power operation;
- and
- shutting off the fluid during a low power operation of the turbine engine and during a mid-level power operation of the turbine engine.
A turbine engine comprising:
- a combustor comprising a fuel injector having a mixer assembly with a pilot mixer and a main mixer, the pilot mixer and the main mixer operating during a high power operation of the turbine engine;
- and
- a fluid injection system in fluid communication with the combustor, the fluid injection system injecting a fluid into the combustor during the high power operation of the turbine engine,
- wherein the fluid is shut off during a low power operation of the turbine engine and during a mid-level power operation of the turbine engine.
