Firing rate

During operation, burner output varies between:
 Maximum output, selected from within area A.
 The minimum output must not be lower than the minimum
limit of the diagram: 300 kW
4.9

Test boiler

The firing rates were obtained in special test boilers, according to
EN 676 standard.
In Fig. 4 you can see the diameter and length of the test
combustion chamber.

Commercial boilers

Burners are suitable for operating on both flame inversion boilers
(*) as well as on boilers with a combustion chamber with run-off
from the bottom (three flue passes) on which the best results for
low NO emissions are obtained.

The boiler front door maximum thickness must not exceed 250
mm (Fig. 5).
Although combination is guaranteed when boiler has a CE type-
approval, preliminary tests are recommended for boilers or
furnaces having a combustion chamber size much different than
the one specified in the diagram (Fig. 4).
(*) For flame inversion boilers, a kit is available to reduce the CO,
if necessary.
