Technical description of the burner
4.8 Firing rate
MAXIMUM OUTPUT must be selected in the hatched area of the
diagram (Fig. 3).
MINIMUM OUTPUT must not be lower than the minimum limit
shown in the diagram.
4.9 Test boiler
The burner/boiler matching does not pose any problems if the
boiler is CE type-approved and its combustion chamber dimen-
sions are similar to those indicated in diagram (Fig. 4).
If the burner must be combined with a boiler that has not been CE
type-approved and/or its combustion chamber dimensions are
clearly smaller than those indicated in diagram (Fig. 4), consult
the manufacturer.
The firing rates were set in relation to special test boilers, accord-
ing to EN 676 regulations.
Fig. 4 indicates the diameter and length of the test combustion
chamber.
Example:
Output 3000 kW
diameter 100 cm
length 4 m
WARNING
The firing rate area values (Fig. 3) have been ob-
tained considering a surrounding temperature of
20 °C, and an atmospheric pressure of 1013 mbar
(approx. 0 m above sea level) and with the com-
bustion head adjusted as shown on page 19.
