To provide a method, system, and apparatus relating to a reheat combustion turbine engine with exhaust gas recirculation.
A method is for controlling a power plant that includes a working fluid. The power plant includes a combustion system having an upstream combustor operably connected to a high-pressure turbine, and a downstream combustor operably connected to a low-pressure turbine. The method includes the steps of: supplying compressed oxidant to at least one of the upstream and downstream combustors; supplying fuel to at least one of the upstream and downstream combustors; combusting the fuel with the compressed oxidant; recirculating the working fluid; controlling the power plant such that at least one of the upstream combustor and the downstream combustor operates at a preferred stoichiometric ratio; and extracting the working fluid from an extraction point positioned relative to either one of the upstream combustor and the downstream combustor that operates at the preferred stoichiometric ratio.
