Abstract: A power plant includes an exhaust duct downstream from an outlet of a turbine which receives exhaust gas from the turbine outlet, a first ejector having a primary inlet that is fluidly coupled to a turbine extraction port and an outlet that is in fluid communication with the exhaust duct. The power plant further includes a second ejector having a primary inlet fluidly coupled to the compressor extraction port, a suction inlet in fluid communication with an air supply and an outlet in fluid communication with a suction inlet of the first ejector. The first ejector cools the stream of combustion gas via compressed air extracted from the compressor and cooled via the second ejector. The cooled combustion gas mixes with the exhaust gas within the exhaust duct to provide a heated exhaust gas mixture downstream from the exhaust duct.

Abstract: A power plant includes a turbine having a plurality of turbine stages and an extraction port in fluid communication with one or more of the turbine stages. The extraction port 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. The exhaust duct is fluid communication with the extraction port. A coolant injection system injects a coolant into the stream of combustion gas to provide cooled combustion gas to the exhaust duct. The cooled combustion gas flows into the exhaust duct at a temperature that is higher than a temperature of the exhaust gas, thereby increasing the temperature of the exhaust gas within the exhaust duct. The increase in thermal energy may be used to produce steam downstream from the exhaust duct.

Abstract: A power generation system may include a generator; a gas turbine system for powering the generator, the gas turbine system including a turbine component, an integral compressor and a combustor to which air from the integral compressor and fuel are supplied, the combustor arranged to supply hot combustion gases to the turbine component, and the integral compressor having a flow capacity greater than an intake capacity of at least one of the combustor and the turbine component, creating an excess air flow. A first control valve system controls flow of the excess air flow along an excess air flow path to a supplemental gas turbine system. The excess air flow may be combusted with a fuel and supplied to the supplemental gas turbine system. An eductor may be positioned in the excess air flow path for using the excess air flow as a motive force to augment the excess air flow with additional gas.

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.
