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 ).
