Combustor Anomaly Monitoring Using Emissions Feedback
DRIVE
April 9, 2026
A system for monitoring for a combustor anomaly in a gas turbine (GT) system is provided. The system includes an emissions probe for each combustor element in the GT system and emissions analyzer(s) operatively coupled to the emissions probes to periodically measure an emissions level of the exhaust flow from each emissions probe. A combustor anomaly detection system is connected to the emissions analyzer(s) and determines whether the emissions level at a select emissions probe of the emissions probes deviates from an expected emissions level by more than a predetermined threshold. Where the emissions level so deviates, the system identifies that a combustor element anomaly exists for the combustor element from which the exhaust flow originates and adjusts operation of the combustor element having the combustor element anomaly. The system provides accurate identification of combustor anomalies without the use of a large number of temperature and/or pressure sensors.
