Technical description of the burner
4 Trace a vertical line from
point A
(Fig. 4), and find the max-
imum pressure
“H2”
of the firing rate.
5 Multiply
“H2”
by
“F”
to obtain the maximum lowered pres-
sure
“H3”
of the firing rate
H3 = H2 x F
(mbar).
– If
“H3”
is greater than
“H1”
(Fig. 4), the burner can supply
the required output.
– If
“H3”
is less than
“H1”
, it is necessary to reduce the burner
output.
The reduction in output is accompanied by a reduction in the
combustion chamber pressure:
Qr
= reduced output
H1r
= reduced pressure
Example
, 5% reduction in output:
Qr = Q x 0.95
H1r = H1 x (0.95)
2
With the new values - Qr and H1r - repeat steps 2 - 5.

4.8 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. 5).
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 established in special test boilers, according
to EN 676 regulations.
In Fig. 5 you can see the diameter and length of the test combus-
tion chamber.
Example:
Output 756 kW - diameter 60cm - length 2m.
WARNING
The combustion head should be adjusted in rela-
tion to the equivalent output
Qe
.
