Abstract: Methods and systems for imparting corrosion resistance to gas turbine engines are disclosed. Existing and/or supplemental piping is connected to existing compressor section air extraction piping and turbine section cooling air piping to supply water and anti-corrosion agents into areas of the gas turbine engine not ordinarily and/or directly accessible by injection of cleaning agents into the bellmouth of the turbine alone and/or repair methods. An anti-corrosion mixture is selectively supplied as an aqueous solution to the compressor and/or the turbine sections of the gas turbine engine to coat the gas turbine engine components therein with a metal passivation coating which mitigates corrosion in the gas turbine engine.

Abstract: A power plant includes a first gas turbine and a second gas turbine. The first gas turbine includes a turbine extraction port that is in fluid communication with a hot gas path of the turbine and an exhaust duct that receives exhaust gas from the turbine outlet. The power plant further includes a first gas cooler having a primary inlet fluidly coupled to the turbine extraction port, a secondary inlet fluidly coupled to a coolant supply system and an outlet in fluid communication with the exhaust duct. The first gas cooler provides a cooled combustion gas to the exhaust duct which mixes with the exhaust gas to provide an exhaust gas mixture to a first heat exchanger downstream from the exhaust duct. At least one of a compressor and a turbine of the second gas turbine are in fluid communication with the outlet of the first gas cooler.

Abstract: A power plant includes a compressor, a combustor downstream from the compressor and a turbine disposed downstream from the combustor. The compressor includes a compressor extraction port. The turbine includes a turbine extraction port that is in fluid communication with a hot gas path of the turbine and which provides a flow path for a stream of combustion gas to flow out of the turbine. An exhaust duct is disposed downstream from the turbine and receives exhaust gas from the turbine. An ejector coupled to the turbine extraction port and to the compressor extraction port cools the stream of combustion gas upstream from the exhaust duct. The cooled combustion gas flows into the exhaust duct at a higher temperature than the exhaust gas and mixes with the exhaust gas within the exhaust duct to provide a heated exhaust gas mixture to a heat exchanger downstream from the exhaust duct.

Abstract: A power plant includes an exhaust duct that receives an exhaust gas from an outlet of the turbine outlet and an ejector having a primary inlet fluidly coupled to a compressor extraction port. The ejector receives a stream of compressed air from the compressor via the compressor extraction port. The power plant further includes a static mixer having a primary inlet fluidly coupled to a turbine extraction port, a secondary inlet fluidly coupled to an outlet of the ejector and an outlet that is in fluid communication with the exhaust duct. A stream of combustion gas flows from a hot gas path of the turbine and into the inlet of the static mixer via the turbine extraction port. The static mixer receives a stream of cooled compressed air from the ejector to cool the stream of combustion gas upstream from the exhaust duct. The cooled combustion gas mixes with the exhaust gas within the exhaust duct to provide a heated exhaust gas mixture to a heat exchanger.
