operating hours

Consistent Performance with Improved Results in Diverse Applications

  • Cyclic, mid-cyclic, and baseload operations, rapidly adjustable to meet fluctuating power demands and environmental mandates
  • District heating
  • Industrial, refinery cogeneration
  • Integrated water and power plant, water desalination
  • Aluminum industry for smelters

9F.04 … Lowest Life Cycle Cost in Its Class

  • Advanced Gas Path (AGP) in the 9F.04 provides enhanced performance with reliable, cost-effective operation.
  • Delivers 15 MW of additional output and 0.8% points of improved efficiency in simple cycle.
  • AGP utilizes improved materials, cooling, and sealing and is retrofitable to 9F.03 units to enable commonality across installed units.
  • Builds upon over 140 F-class AGP installations and over 500,000 operating hours.
  • Extended 32,000-hour combustion and hot gas path inspection intervals, with most parts lasting multiple cycles.

Engineered to Respond Quickly and Efficiently When Needs or Conditions Change

  • More than 97 percent average start-up reliability
  • Low cumulative NOx emissions that meet annual tonnage limits even while operating in cyclic duty
  • Faster start times that can speed the entire start sequence—up to 15 minutes in simple cycle, and 20 minutes in combined cycle

Robust Operation During Weather, Fuel, and Grid Variations

  • Better availability with closed-loop, real-time combustion system tuning
  • More fuel flexibility, up to 20 percent Modified Wobbe Index (MWI) variation in natural gas
  • Improved survivability from grid disruptions and load transients

Load Range Expansion, Efficiency, Responsiveness, and Customization

  • Larger emissions-compliant operating range; staying online to attain higher dispatch priority; increased available load range for dispatch
  • Good emissions citizenship; staying online while reducing greenhouse gases
  • Less fuel usage by staying online and avoiding start/stop cycle costs

Enhancements for Reliable Cost-Effective Operation 

  • 99 percent average reliability
  • Improved compressor that increases reliability and availability, while reducing periodic inspections and maintenance costs
  • OpFlex* AutoTune, which improves Dry Low NOx (DLN) operability and eliminates firing-temperature suppression
  • Mark* VIe Control Platform real-time physics-based modeling that increases overall performance, operability, and reliability
