Gas turbine engine systems and methods for imparting corrosion resistance to gas turbine engines

A gas turbine engine system comprising:

• a gas turbine engine, the gas turbine engine having a compressor section, a combustion system, a turbine section, compressor section air extraction piping and turbine section cooling air piping;
• water supply piping, the water supply piping being in fluid communication with a supply of water;
• a supply of an anti-corrosion agent comprising a polyamine corrosion inhibitor;
• anti-corrosion agent supply piping, the anti-corrosion agent supply piping being in fluid communication with the supply of an anti-corrosion agent comprising the polyamine corrosion inhibitor;
• a mixing chamber, the mixing chamber being in fluid communication with the water supply piping and the anti-corrosion agent supply piping, the mixing chamber being configured to receive water from the water supply piping and the anti-corrosion agent from the anti-corrosion agent supply piping to produce an anti-corrosion mixture, the anti-corrosion mixture being a mixture of the anti-corrosion agent and water;
• and
• anti-corrosion mixture supply piping, the anti-corrosion mixture supply piping being in fluid communication with the mixing chamber and the compressor section air extraction piping and the turbine section cooling air piping to selectively supply the anti-corrosion mixture to the compressor section and/or the turbine section of the gas turbine engine, wherein the anti-corrosion mixture is introduced into the compressor section or turbine section of the gas turbine engine as an aqueous solution.
