Abstract: An improved intake arrangement, for a compressor having a compressor blading, includes a manifold divided by a barrier into two sections, to convey, from one section, a flue gas stream, and, from other section, an air stream. Further, the intake arrangement includes a converging section configured to the manifold and extends convergingly to the compressor defining an inlet to the compressor blading. The converging section includes inner and outer ring members disposed coaxially to each other, between which there extends, coaxially and convergingly, the barrier to at least up to a certain distance within the converging section, defining a converging nozzle therebetween. The converging nozzle includes a mixing feature adapted to enhance mixing of the flue gas and air streams.

Abstract: A power plant including a gas turbine, a heat recovery boiler arrangement. The gas turbine includes a compressor inlet with a fresh air intake sector and an intake section for recirculated flue gas. A common control element for the control of the fresh air flow and of the recirculated flue gas flow is arranged in the compressor and/or in the compressor intake. Besides the power plant, a method to operate such a power plant is an object of the invention.
