Abstract: An intake arrangement for a compressor in a gas turbine power plant includes at least a passageway having an elongated portion, and a circular portion at an end of the elongated portion. The circular portion may be arranged in proximity to the compressor at around a compressor inlet. The passageway may be divided at least circumferentially and radially across the entire elongated portion and at least partially across the circular portion to configure a plurality of flue gas and air inlet segments for respectively conveying flue gas and air streams therethrough. The flue and air gas streams from each of the respective plurality of flue gas and air inlet segments, converge to be blended into a target mass stream for being conveyed into the compressor.

Abstract: What is described is a method for operating a gas turbine power plant, in which fresh air is delivered to a compressor inlet and is accelerated in the compressor inlet and a recirculated first exhaust gas substream is delivered into a region of the compressor inlet in which the fresh air is accelerated to an extent such that the difference between total pressure and static pressure in the fresh air 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 into the compressor inlet. What is described, further, is a gas turbine power plant with a gas turbine, the compressor inlet of which is divided into two sectors which the flow duct of the compressor adjoins, a feeder for fresh air being connected to the first sector and a recirculation line for recirculating the first exhaust gas substream being connected to the second sector, and the second sector reaching so close to the compressor that, when the gas turbine is in operation, the static pressure at the outlet of the second sector is so low that the difference between total pressure and static pressure 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 into the compressor inlet.

Abstract: The invention relates to a gas turbine plant, including a gas turbine device, which has a compressor and at least one burner and at least one gas turbine, a waste heat boiler assembly, which has a boiler inlet side connected to a turbine outlet and a first boiler outlet connected to a flue and a second boiler outlet, and an exhaust gas recirculation, which connects the second boiler outlet to a compressor inlet. A simplified structure can be achieved in that the waste heat boiler assembly has a first boiler exhaust gas path, which is connected to the boiler inlet side and leads to the first boiler outlet, and that the waste heat boiler assembly has a second boiler exhaust gas path, which is connected to the boiler inlet side and leads to the second boiler outlet separately from the first boiler exhaust gas path.

Abstract: The invention discloses a method for operating a combined cycle power plant with an integrated CO2 capture unit, wherein flue gas of a gas turbine is led along an flue gas path through a heat recovery steam generator, a flue gas cooling circuit and a CO2 absorber. A reduction in effort is achieved by operating the gas turbine to have a back-pressure at its exit, which compensates most or all of the pressure loss of the flue gas along the flue gas path.
