300 mg/Nm3 for Natural Gas firing.

The emissions are referred to these operating conditions:

  • Air excess 5%
  • Air temperature ≤ 450°C
  • Furnace temperature ≤ 1250°C
  • Burner load ≥ 80%

The reported value is the expected one. The guaranteed value will be fixed case by case according to furnace type and working conditions.
