Il seguente diagramma mostra le variazioni di emissioni di NOx in funzione dei valori di O

nei fumi, ottenuti da test di laboratorio
bruciando gas naturale.
NOTE:
The performance curve is a diagram that represents the burner performance in the type approval phase or in the laboratory tests, but does not
represent the regulation range of the machine..
To get the input in kcal/h, multiply value in kW by 860.
Data are referred to standard conditions: atmospheric pressure at 1013mbar, ambient temperature at 15° C
