NOx emissions: 70 mg/Nm³ @ 3% O2 for Natural Gas 

The emissions are referenced for these operating conditions: 

• Air excess 5% 
• Air temperature less than or equal to 520°C 
• Furnace temperature less than or equal to 1250°C 
• Burner load á 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.)
