Burner output
The firing rates were obtained in special
test boilers, according to EN 676 regula-
tions.
Fig. 4 indicates the diameter and length of
the test combustion chamber.
Example
D715
Output 756 kW (650 Mcal/h):
diameter 60 cm,
length 2m.
The coupling is ensured when the boiler is EC
type-approved; for boilers or ovens with com-
bustion chambers of very different dimensions
compared to those shown in the diagram of
Fig. 4, preliminary checks are recommended.
