What Can DLN 2.6+ Do for You?

  • Reduce NOx emissions to as low as 5 ppm across large load and ambient temperature range of 0°F–120°F
  • Increase availability and lower maintenance costs due to 32,000 factored fired hour (FFH) and 1,250 factored fired start (FFS) combustion intervals
  • Broaden fuel flexibility for gas fuels with up to 30 percent Modified Wobbe Index (MWI), 25 percent ethane/propane, 20 percent hydrogen and a wide range of distillate fuels
  • Extend turndown to as low as 37 percent of baseload for off-peak fuel savings and fast dispatch
  • Enhance Advanced Gas Path (AGP) and compressor upgrade performance and operability
  • Improve flexibility when combined with OpFlex controls software including AutoTune, Fast Start, Cold-Day Performance, and Extended Turndown
  • Eliminate costly diluent injection or Selective Catalytic Reduction (SCR) systems, and the drawbacks associated with ammonia utilization
