What Can Upgrading Do for You?

Turndown Configuration

  • Reduce NOx/CO-compliant turndown to 35 percent of baseload with inlet bleed heating, a 25 percent improvement from previous limits
  • Improve baseload performance and emissions: 85 percent reduction in CO emissions combined with heat rate and output improvements of 0.25 percent and 0.4 percent, respectively, with no impact on exhaust energy
  • Increase part-load simple-cycle efficiency: more than 2 percent reduction in heat rate at 70 percent gas turbine load

Peak Fire Configuration

Increase simple-cycle output by up to 7.6 percent by peak firing up to 100°F with no impact on NOx emissions or turndown, and with CO levels 70 percent lower than at baseload.
