Gas turbine power plant with exhaust gas recirculation

A method for operating a gas turbine power plant with exhaust gas recirculation, the gas turbine power plant including a gas turbine with a compressor having an inlet, a waste heat recovery steam generator, an exhaust gas divider, a recirculation line, and an exhaust gas recooler, said method comprising:

• delivering fresh air into the compressor inlet, the fresh air being accelerated in the compressor inlet;
• controlling the exhaust gas divider to divide exhaust gases from the gas turbine into (1) a first exhaust gas substream for recirculation into an intake stream of the gas turbine and (2) into a second exhaust gas substream for discharge from the gas turbine power plant;
• recirculating the first exhaust gas substream for delivery, separately from the fresh air, into the compressor inlet;
• delivering the recirculated first exhaust gas substream, separately from the fresh air, as far as a region of the compressor inlet in which the fresh air is accelerated to an extent such that a difference between total pressure and static pressure in the accelerated fresh air is greater than or equal to a pressure difference for sucking a target mass flow of the recirculated first exhaust gas substream into the compressor inlet;
• introducing the recirculated first exhaust gas substream to the accelerated fresh air via a plurality of delivery ducts arranged so as to be distributed circumferentially, upstream of the compressor, on a diameter of an intake duct and concentrically to a shaft of the gas turbine;
• and
• controlling a quantity of the recirculated first exhaust gas substream by changing an axial position of outlet orifices of the plurality of delivery ducts relative to the compressor inlet.
