Abstract
A method for controlling NOx emissions from a gas turbine having a fuel adjustment system may include setting an outer nozzle fuel flow to achieve a desired level of combustion dynamics for at least one of a plurality of combustion chambers, determining a delta adjustment value for a center nozzle fuel flow that will result in a desired level of NOx emissions from the gas turbine, and adjusting the center nozzle fuel flow according to the determined delta adjustment value to obtain the desired level of NOx emissions from the gas turbine.
