Technical description of the burner
4.8 Firing rates
The MAXIMUM OUTPUT is chosen from within the continuous
diagram area (Fig. 3).
The
MINIMUM OUTPUT must not be lower than the minimum
limit of the diagram:
RS 1300/EV C01 FS1 = 2500 kW
RS 1600/EV C01 FS1 = 3065 kW
RS 2000/EV C01 FS1 = 4000 kW
4.9 Test boiler
The burner/boiler combination does not pose any problems if the
boiler is EC approved and its combustion chamber dimensions
are similar to those indicated in the diagram (Fig. 4).
If the burner must be combined with a boiler that has not been EC
approved and/or its combustion chamber dimensions are clearly
smaller than those indicated in the diagram, consult the manufac-
turer.
The firing rates were set in relation to special test boilers, accord-
ing to EN 676 regulations. In Fig. 4 you can see the diameter and length of the test combus-
tion chamber.
Example:
Output 13000 kW - diameter 120 cm - length 9 m
MODULATING RATIO
The modulating ratio, obtained in test boilers in accordance with
EN 676, is 1:5.
WARNING
The firing rate value (Fig. 3) has been obtained
considering an ambient temperature of 20 °C, an
atmospheric pressure of 1013 mbar (approx. 0 m
a.s.l.), and with the combustion head adjusted as
shown on page 21.
