Method and apparatus for low emission gas turbine energy generation

A low-emission method for producing power using a gas turbine (2) includes premixing a plurality of fuel and air mixtures, injecting the fuel and air mixtures into a combustion chamber (13) using a plurality of fuel nozzles (11, 12), and adjusting a ratio of fuel and air injected by at least one of the nozzles to control a fuel/air concentration distribution within the combustion chamber.
