Abstract
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. The recirculation loop may include: a recirculation compressor; an upstream combustor; a high-pressure turbine; a downstream combustor; a low-pressure turbine; and a recirculation conduit configured to direct the outflow of working fluid from the low-pressure turbine to the recirculation compressor. The power plant may include: 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 on the recirculation loop.
