ABSTRACT:
An embodiment may comprise a system for controlling NOx emissions from a turbine having combustion chambers. The system may comprise a center fuel flow and a plurality of outer fuel flows for each of a plurality of combustion chambers. An outer fuel flow is set to achieve a desired level of combustion dynamics for at least one of the plurality of combustion chambers. A delta adjustment value is determined for the center fuel flow that will result in a desired level of NOx emissions from the turbine, and for adjusting the center fuel flow according to the determined delta adjustment value to obtain the desired level of NOx emissions from the turbine.
