Abstract: A power generation system may include a 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 is arranged to supply hot combustion gases to the turbine component, and the integral compressor has a flow capacity greater than an intake capacity of the combustor and/or 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 an exhaust of the turbine component. An eductor positioned in the excess air flow path uses the excess air flow as a motive force to augment the excess air flow with additional gas, creating an augmented excess gas flow.

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.

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. A static mixer 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 generation system includes: a first gas turbine system including a first turbine component, a first integral compressor and a first combustor to which air from the first integral compressor and fuel are supplied, the first combustor arranged to supply hot combustion gases to the first turbine component, and the first integral compressor having a flow capacity greater than an intake capacity of the first combustor and/or the first turbine component, creating an excess air flow. A second gas turbine system may include similar components to the first except but without excess capacity in its compressor. A control valve system controls flow of the excess air flow from the first gas turbine system to the second gas turbine system. A cooling fluid injector may be coupled to the excess air flow path for injecting a cooling fluid such as water or steam into the excess air flow.

Abstract: A power plant includes a turbine disposed downstream from a combustor. The turbine includes an 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 extraction port and to an air supply 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. The cooled combustion gas mixes with the exhaust gas within the exhaust duct to provide a heated exhaust gas mixture to a heat exchanger disposed downstream from the exhaust duct. The heat exchanger may extract thermal energy from the exhaust gas mixture to produce steam.
