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 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 system for controlling gas turbine output for a gas turbine power plant is disclosed herein. The power plant includes a gas turbine including a combustor downstream from a compressor, a turbine downstream from the combustor and an exhaust duct downstream from the outlet of the turbine. The exhaust duct receives exhaust gas from the turbine outlet. The system further includes an exhaust damper operably connected to a downstream end of the exhaust duct. The exhaust damper increases backpressure at the turbine outlet and restricts axial exit velocity of the exhaust gas exiting the turbine outlet when the exhaust damper is partially closed. A method for controlling gas turbine output is also provided herein.

Abstract: A system and method for supercharging a combined cycle system includes a forced draft fan providing a variable air flow. At least a first portion of the air flow is directed to a compressor and a second portion of the airflow is diverted to a heat recovery steam generator. A control system controls the airflows provided to the compressor and the heat recovery steam generator. The system allows a combined cycle system to be operated at a desired operating state, balancing cycle efficiency and component life, by controlling the flow of air from the forced draft fan to the compressor and the heat recovery steam generator.

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 controls flow of the excess air flow along an excess air flow path to a burner module in which the excess air flow and a fuel are combusted. An exhaust of the burner module and an exhaust of the turbine component can be directed to an HRSG. 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 air.
