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.

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 method to adjust the back pressure applied to an exhaust of a gas turbine, the method including: exhausting hot combustion gas from the gas turbine; passing the hot combustion gas through a heat recovery steam generator; actuating an exhaust gas damper in the stream of the hot combustion gases, wherein actuation moves the exhaust gas damper to a restricted position, and while in the restricted position, the exhaust damper creates a backpressure applied to the exhaust gas, wherein the backpressure reduces an exhaust gas velocity at an exhaust of the gas turbine.
