Systems and apparatus relating to reheat combustion turbine engines with exhaust gas recirculation

A power plant (9) configured to include a recirculation loop (10) about which a working fluid is recirculated, the recirculation loop (10) 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 (10) may include: a recirculation compressor (12); an upstream combustor (22); a high-pressure turbine (30); a downstream combustor (24); a low-pressure turbine (32); and a recirculation conduit (40) configured to direct the outflow of working fluid from the low-pressure turbine (32) to the recirculation compressor (12). The power plant may include: an oxidant compressor (11) configured to provide compressed oxidant to both the upstream combustor (22) and the downstream combustor (24); and means for extracting a portion of the working fluid from an extraction point (51,75,76) disposed on the recirculation loop (10).
