<p>What is described is a method for operating a gas turbine power plant, in which fresh air (2) is delivered to a compressor inlet (3) and is accelerated in the compressor inlet (3) and a recirculated first exhaust gas substream (21) is delivered into a region of the compressor inlet (3) in which the fresh air (2) is accelerated to an extent such that the difference between total pressure and static pressure in the fresh air (2) is greater than or equal to a pressure difference which is required in order to suck a target mass flow of the recirculated first exhaust gas substream (21) into the compressor inlet (3). What is described, further, is a gas turbine power plant with a gas turbine (6), the compressor inlet of which is divided into two sectors (3', 3'') which the flow duct of the compressor (1) adjoins, a feeder for fresh air being connected to the first sector (3') and a recirculation line for recirculating the first exhaust gas substream (21) being connected to the second sector (3''), and the second sector (3''). reaching so close to the compressor (1) that, when the gas turbine (6) is in operation, the static pressure at the outlet of the second sector (3'') is so low that the difference between total pressure and static pressure is greater than or equal 20 to a pressure difference which is required in order to suck a target mass flow of the recirculated first exhaust gas substream (21) into the compressor inlet (3).</p> |
