Abstract: A power plant includes a first gas turbine and a second gas turbine. The first gas turbine includes a turbine extraction port that is in fluid communication with a hot gas path of the turbine and an exhaust duct that receives exhaust gas from the turbine outlet. The power plant further includes a first gas cooler having a primary inlet fluidly coupled to the turbine extraction port, a secondary inlet fluidly coupled to a coolant supply system and an outlet in fluid communication with the exhaust duct. The first gas cooler provides a cooled combustion gas to the exhaust duct which mixes with the exhaust gas to provide an exhaust gas mixture to a first heat exchanger downstream from the exhaust duct. The first gas cooler is also in fluid communication with a combustor of the second gas turbine.

Abstract: A gas turbine fuel heating system is disclosed having at least one coalescing filter configured to accept a main fuel supply and a plurality of fuel circuit heaters. Each fuel circuit heater can be configured to accept an independent fuel circuit portion of the main fuel supply leaving the at least one coalescing filter and also configured to accept a heating medium circuit portion of a heating medium. The system can have a plurality of scrubbers, a plurality of fuel circuit manifolds, and a plurality of fuel premix tubes. A controller circuit determines the MWI for each independent fuel circuit portion and adjusts the heating medium circuit portion passed to the corresponding fuel circuit heater to maintain at least one parameter selected from the group consisting of a baseline independent fuel circuit portion MWI setpoint and a predetermined independent fuel circuit portion nozzle gas injector pressure ratio.

Abstract: A system includes a controller configured to control a heated flow discharged from an outlet of a mixing chamber 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 the mixing chamber. The controller is configured to control at least one of a pressurized flow of the compressor to the mixing chamber and a steam flow to the mixing chamber. The TEG flow is extracted through a turbine casing. The heated flow includes the TEG flow and the at least one of the pressurized flow and the steam flow.

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.
