Abstract:
1. A computerized method, implemented by a processing unit, for dynamically tuning a combustor of a gas turbine (GT) engine, the method comprising: monitoring parameters of the GT engine during operation, wherein the parameters quantify at least one of combustion dynamics or emission composition; detecting that a plurality of the monitored parameters exceed predetermined upper or lower limits; identifying the plurality of monitored parameters that exceed the predetermined upper or lower limits as exhibiting an out-of-tune condition; comparing the identified parameters against a scanning order table to determine which one of the identified parameters is highest ranked; selecting a fuel-flow split for adjustment based, in part, on at least one of the identified parameters exhibiting the out-of-tune condition, wherein the process of selecting comprises: incrementally adjusting the selected fuel-flow split a predefined amount.
