Technical description of the burner
4.8 Firing rates
The MAXIMUM OUTPUT is chosen from within the diagram area
(Fig. 2).
The
MINIMUM OUTPUT must not be lower than the minimum
limit of the diagram:
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. 3).
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 obtained in special test boilers, according to
EN 676 regulations.
In Fig. 3 you can see the diameter and length of the test combus-
tion chamber.
Example:
Output 7000 kW - diameter 120 cm - length 6 m.
Model kW
RS 810/M BLU 1200
WARNING
The firing rate value (Fig. 2) has been obtained
considering an ambient temperature of 20C, an
atmospheric pressure of 1013 mbar (approx. 0 m
a.s.l.), and with the combustion head adjusted as
shown on page 19.
