Technical description of the burner
4.6 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:
RL 800/M = 1750 kW
4.7 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 7000 kW:
diameter 120 cm,
length 6m.
MODULATION RATIO
The modulation ratio, determined using test boilers according to
standard (EN 676 for gas, EN 267 for light oil), is 2.4 : 1.
WARNING
The FIRING RATE area values (Fig. 3) have been
obtained considering a surrounding temperature
of 20 °C, and an atmospheric pressure of 1013
mbar (approx. 0 m above sea level) and with the
combustion head adjusted as shown on page 17.
