Technical description of the burner
3.7 Firing rates
The MAXIMUM OUTPUT must be selected within area A.(Fig. 2).
The MINIMUM OUTPUT must not be lower than the minimum
limit of the diagram: 600 kW
3.8 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
manufacturer. The firing rates were obtained in special test boilers, according to
EN 676 standard.
In Fig. 3 you can see the diameter and length of the test
combustion chamber.
Example:
Output 650 Mcal/h - diameter 60 cm - length 2 m
ATTENTION
The firing rate value (Fig. 2) 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 18.
