Ambient air is compressed into a compressed ambient gas flow with a main air compressor. The compressed ambient gas flow having a compressed ambient gas flow rate is delivered to a turbine combustor and mixed with a fuel stream having a fuel stream flow rate and a portion of a recirculated gas flow to form a combustible mixture. The combustible mixture is burned and forms the recirculated gas flow that drives a turbine. The recirculated gas flow is recirculated from the turbine to the turbine compressor using a recirculation loop. At least one emission level is measured by at least a first emission sensor in the recirculated gas flow and at least a first control signal is generated. The fuel stream flow rate is adjusted based on the at least a first control signal to achieve substantially stoichiometric combustion.
