Technical description of the burner
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 3000 kW - diameter 100 cm - length 3.5 m
