Claim 10:
11. A method of washing an on-line gas turbine engine, the gas turbine engine including a compressor, a combustor, a gas turbine, the combustor including a plurality of late lean fuel injectors distal to a head end of the combustor, adjacent to an upstream side of the gas turbine, and supplied with a secondary fuel to an interior of the combustor, the method comprising:
supplying water from a water source to a mixing chamber of a wash system;
supplying a first fluid from a first fluid source to a mixing chamber of the wash system, the first fluid providing vanadium ash and vanadium deposit mitigation and removal from internal components of the gas turbine;
supplying the water and first fluid to the mixing chamber including pumping water from the water source and pumping the first fluid from the first fluid source; and
injecting fluid from the mixing chamber to at least one of the plurality of late lean fuel injectors while the gas turbine engine is on-line, wherein each late lean fuel injector in the plurality of late lean fuel injectors are configured to inject the fluid from the mixing chamber in a direction substantially transverse to a longitudinal direction of the combustor.
