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. |

1. An intake arrangement for a gas turbine engine having a compressor and a compressor blading configured thereon, the intake arrangement, comprising:
a manifold having first and distal second end portions, the second end portion being proximate to the compressor, the manifold having at least one barrier configured to divide the manifold into at least two sections extending from the first to the second end portion, to convey, from the at least one section, a flue gas stream, and, from the at least other section, an air stream, entering from the first end portion; and a converging section configured along the second end portion of the manifold and extending convergingly to the compressor and defining an inlet to the compressor blading, the converging section having inner and outer ring members disposed coaxially to each other, wherein between the inner and outer ring members there extends, coaxially and convergingly, the at least one barrier to at least up to a distance in the converging section, defining a converging nozzle therebetween, wherein the converging nozzle comprises a mixing feature adapted to provide turbulence in the flue gas and air streams upon deployment therefrom, creating a region of high vorticity ‘R’ in the converging section to promote mixing of the flue gas and air streams to convey mixed composition of the flue gas and air streams to the compressor blading, improving the compressor operating range. |
