Abstract: The present application provides a power generation system. The power generation system may include a gas turbine engine for creating a flow of combustion gases, a steam turbine, and a steam turbine preheating system. The steam turbine preheating system may receive an extraction of the flow of combustion gases and delivers the extraction to the steam turbine to preheat the steam turbine.

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.

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 plant includes a gas turbine having a combustor downstream from a compressor, a turbine disposed downstream from the combustor and an exhaust duct downstream from an outlet of the turbine. The combustor includes an extraction port that is in fluid communication with a hot gas path of the combustor. The extraction port defines a flow path for a stream of combustion gas to flow out of the hot gas path. The exhaust duct receives exhaust gas from the turbine outlet. A coolant injection system injects a coolant into the stream of combustion gas upstream from the exhaust duct such that the stream of combustion gas blends with the exhaust gas from the turbine within the exhaust duct and forms an exhaust gas mixture within the exhaust duct. A heat exchanger is disposed downstream from the exhaust duct and receives the exhaust gas mixture from the exhaust duct.

Abstract: A system includes a controller communicatively coupled to a compressor. The controller is configured to sense an exhaust temperature of a gas turbine system fluidly coupled to the compressor and derive a setpoint based on the sensed exhaust temperature. The controller is also configured to actuate an inlet bleed heat valve based on the derived setpoint and an ambient temperature. The inlet bleed heat valve directs a compressor fluid from the compressor into a fluid intake system fluidly coupled to the compressor upstream of the compressor and configured to intake a fluid.

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 system includes a controller configured to control a heated flow discharged from an outlet of an eductor to an inlet control system to control a temperature of an intake flow through a compressor inlet of a compressor of a gas turbine system. The controller is configured to control a turbine extraction gas (TEG) flow to a motive inlet of the eductor. The controller is configured to control a suction flow to a suction inlet of the eductor. The TEG flow is extracted through a turbine casing, and the heated flow includes the TEG flow and the suction flow.
