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, a gas turbine, and multiple premixing nozzles, the combustor including a plurality of late lean fuel injectors supplied with secondary fuel to an interior of the combustor and disposed downstream from the premixing nozzles;
• 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 water pump configured to pump water;
• an anti-corrosion agent fluid source supplying a supply of an anti-corrosion agent fluid including a amine corrosion inhibitor;
• anti-corrosion agent fluid supply piping, the anti-corrosion agent fluid supply piping being in fluid communication with the anti-corrosion agent fluid source;
• a first fluid pump configured to pump the anti-corrosion agent fluid to the mixing chamber;
• a mixing chamber in communication with the water source and the anti-corrosion agent fluid source;
• the mixing chamber being in fluid communication with water supply piping and the anti-corrosion agent fluid supply piping, the mixing chamber being configured to receive water from the water supply piping and the anti-corrosion agent fluid from the anti-corrosion agent fluid supply piping to produce an anti-corrosion mixture, the anti-corrosion mixture including a mixture of the amine corrosion inhibitor and water;
• 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, amine corrosion inhibitor, or an mixture of amine corrosion inhibitor and water thereof is injected into the combustor and at least one of the plurality of late lean fuel injectors, bypassing the multiple premixing nozzles, wherein the mixture is injected while the gas turbine engine is off-line.
