4.7 EMISSIONS
Class Limit 3 = 80 mg/kWh
The burners' emission values (according to
EN 676) prove much lower than the limits laid
down by the strictest standards. The flame's di-
stribution and its spread over a large surface
means that the burner manages to limit the for-
mation of thermal NOx, the main causes of pol-
lutant emission.
