Patent ID: 8539749

Claim:
A power plant configured to include a recirculation loop about which a working fluid is recirculated, the recirculation loop comprising a plurality of components configured to accept an outflow of working fluid from a neighboring upstream component and provide an inflow of working fluid to a neighboring downstream component, wherein the recirculation loop includes: a recirculation compressor; an upstream combustor positioned downstream of the recirculation compressor; a high-pressure turbine positioned downstream of the upstream combustor and drivingly connected to the recirculation compressor; a downstream combustor positioned downstream of the high-pressure turbine; a low pressure turbine positioned downstream of the downstream combustor; and a recirculation conduit connected to an inlet of the recirculation compressor configured to direct the outflow of working fluid from the low-pressure turbine to the recirculation compressor, the power plant comprising: an oxidant compressor configured to provide compressed oxidant to both the upstream combustor and the downstream combustor; and means for extracting a portion of the working fluid from an extraction point disposed at a predetermined location on the recirculation loop.
