NOX emissions: 70 mg/Nm³ @ 3% O₂ for Natural Gas
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 on a case by case basis according to the furnace type and the specific operating conditions.)
