Systems and methods for addition of fuel additives to control turbine corrosion

A gas turbine engine system, comprising:

• a gas turbine engine, the gas turbine engine including a compressor, a combustor, and a gas turbine, the combustor including a plurality of late lean fuel injectors supplied with a secondary fuel to an interior of the combustor, the plurality of late lean fuel injectors distal to a head end of the combustor, adjacent to an upstream side of the gas turbine, and configured to supply the secondary fuel in a direction substantially transverse to a longitudinal direction of the combustor;
• and
• a wash system configured to be attached to and in fluid communication with the plurality of late lean fuel injectors of the combustor, the wash system including:
• a water source supplying water;
• a first fluid source supplying a first fluid;
• a mixing chamber in communication with the water source and the first fluid source;
• a water pump configured to pump the water to the mixing chamber;
• a first fluid pump configured to pump the first fluid to the mixing chamber;
• a fluid line configured to be in fluid communication with the mixing chamber and at least one of the plurality of late lean fuel injectors such that a fluid from the mixing chamber including the water, the first fluid, or a mixture thereof is injected into the combustor at at least one of the plurality of late lean fuel injectors,
• wherein the wash system is operated with the gas turbine engine in an off-line mode.
