9F Upgrade Technologies
AutoTune
PSM's AutoTune system provides real-time, automated combustion tuning for the 9F platform. The system continuously adjusts combustion parameters to maintain emissions compliance and combustion dynamics stability across varying ambient conditions (temperature and humidity), fuel composition changes, and normal engine deterioration.
AutoTune eliminates the need for manual combustion tuning during seasonal transitions and reduces the risk of combustion dynamics events that can damage hardware. The system integrates with existing 9F control platforms and can be installed during a scheduled outage.
Key capabilities:
- Automatic NOx and CO emissions optimization
- Combustion dynamics monitoring and active mitigation
- Fuel flexibility support for natural gas and LNG compositions
- Remote monitoring and diagnostics capability
