Today’s challenge for operators
Getting the most from your combustor
Proper Dry Low NOx (DLN) combustor tuning is essential to ensuring regulatory compliance, extending turbine hardware life, and remaining available to reliably generate power and revenue. Weather, fuel property variation, and hardware condition are among the many factors that drive the need for tuning adjustments to ensure robust operation. We understand the drivers for periodic tuning are diverse and have developed a suite of AutoTune solutions to help provide the most possible flexibility for customers.
The AutoTune advantage
GE Vernova’s OpFlex AutoTune system combines Model-Based Control (MBC) with field-validated expert combustion models and a combustion dynamics feedback signal. This system enables continuous, real-time tuning with settings checked 25 times per second, which provides faster response than other systems that rely on emissions feedback.
Model-Based Control (MBC) is the advanced control software platform underpinning AutoTune. Developed for GE Vernova’s aircraft engine business, this modern controls architecture replaces static control schedules used in legacy control system software with modern, online, real-time turbine simulators to enable fast, accurate, adaptive control. This robust platform extends operating flexibility, expands operating envelopes, enables customization, and improves user troubleshooting capability.
GE Vernova was the first to develop a self-contained, automated DLN tuning system in 2007. Today, GE Vernova has more than 10 million hours of automated tuning experience and more than 800 OpFlex AutoTune systems in operation globally—more than 50% of the entire F-class fleet.
