Emissions (at the stack):

• Diluted flame mode: furnace temperature 800° C, air excess 10%:
  • NOx less than 60 ppm @ 3% O2 in Dry Flue Gases
  • CO less than 20 ppm @ 3% O2 in Dry Flue Gases
• Flameless mode: furnace temperature 950° C, air excess 10%:
  • NOx less than 20 ppm @ 3% O2 in Dry Flue Gases
  • CO less than 20 ppm @ 3% O2 in Dry Flue Gases

The reported values are the expected one with natural gas firing. The guaranteed values will be fixed case by case according to furnace type and working conditions.
