120 mg/Nm3 @ 3% O2 for Natural Gas 

The emissions are referenced at these operating conditions: 

  • Air excess 5% 
  • Air temperature less than or equal to 450°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 furnace type and working conditions. 

Typical behaviour of TSN burner NOx emissions at different fuel flow rates (W gas) and at different air excess levels ( e ).
