<p>A method of controlling a power plant 9 that includes a working fluid, wherein the power plant includes a combustion system having an upstream combustor 22 operably connected to a high-pressure turbine 30 and a downstream combustor 24 operably connected to a low-pressure turbine 32. The method may include the steps of: supplying compressed oxidant to at least one of the upstream and the downstream combustor; supplying a fuel to at least one of the upstream and the downstream combustor 22,24; combusting the fuel with the compressed; recirculating the working fluid; controlling the power plant such that one of the upstream and the downstream combustors 22,24 operates at a preferred stoichiometric ratio; and extracting the working fluid from an extraction point 51 positioned relative to the whichever of the upstream combustor and the downstream combustor operates at the preferred stoichiometric ratio.</p> |
