OpFlex Sliding Fuel Pressure Control
Reduce your gas fuel supply pressure requirements during start-up and operation to better accommodate low or fluctuating pressure, as well as reduce likelihood of trips or runbacks.
Today’s challenge for operators
Increasing stability and reliability
Nobody has time for trips or runbacks. Stable and reliable gas turbine operation with low emissions relies on the accurate and fast control of the fuel flow rate supplied to the combustion system. Sliding Fuel Pressure Control enables your turbine to accommodate low or fluctuating gas supply pressure, so you keep operating with confidence.
OpFlex Sliding Fuel Pressure Control features*
- Closed loop control using pressure and valve position feedback with logic to adjust the inter-stage pressure setpoint and balance what actually matters… valve operating limits to maintain stable and accurate fuel flow control.
- Advantages… allows continued operation with lower gas fuel supply pressure by accounting for all GT operating variation
- ambient variation
- fuel variation
- future gas turbine hardware/control upgrades
- actual fuel splits
- combustor mode
- Refined protections to minimize impact to operations.
- Improved flexibility on automatic transfers to liquid fuel
*Note: Features vary by turbine model

Purge Credit
Combined control software and valve hardware system to enable purge to be conducted during prior shutdown, followed by isolation of the fuel manifold with a valve system, such that purge can be skipped on start-up, enabling 15+ min. combined cycle start time savings (NFPA- 85 compliant).
