Classification: CPC F  B  C | IPC B  C  F

Claim 0:
1. 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, the first fluid providing vanadium ash and vanadium deposit mitigation and removal from internal components of the gas turbine;
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 mixture is injected while the gas turbine engine is on-line.
