Abstract: A fuel control system for a gas turbine engine that includes a primary fuel circuit, a fuel tuning circuit, a plurality of combustors connected to the fuel tuning circuit, oxygen and carbon dioxide sensors in the exhaust stream and a feedback control loop operatively connected to the fuel tuning circuit and to the oxygen and carbon monoxide sensors which serve to control the precise amount of fuel and air being fed to each one of the plurality of combustors in the engine. A parallel array of control valves in a tuning fuel circuit connect to corresponding ones of the plurality of combustors in the gas turbine engine. The fuel control system thereby “fine tunes” the amount of fuel and air being fed to each combustor using data regarding the detected oxygen and carbon monoxide concentrations in the exhaust gas as provided through a feedback control loop.

Abstract: A main air compressor delivers a compressed ambient gas flow with a compressed ambient gas flow rate to a turbine combustor. A fuel stream with a flow rate is delivered to the turbine combustor and mixed with the compressed ambient gas flow and an exhaust gas flow and burned with substantially stoichiometric combustion to form the exhaust gas flow and drive a turbine, thus operating the power plant at a first load. A portion of the exhaust gas flow is recirculated from the turbine to the turbine compressor and a portion is delivered to an exhaust path. The fuel stream flow rate and the compressed ambient gas flow rate are reduced, and substantially stoichiometric combustion is maintained and the power plant is operated at a second load. The fuel stream flow rate is further reduced and lean combustion is achieved and the power plant is operated at a third load.
