Calculation of
burner output
Q F = Burner output (kW)
Q N = Rated boiler output(kW)
η = Boiler efficiency (%)
Q F = Q N x 100
η
Working diagrams
The working diagram shows
burner output as a function of
combustion chamber pressure.
It corresponds to the maximum
values specified by EN 276
measured at the test fire tube.
Boiler efficiency should be
taken into consideration when
selecting the burner.

kcal/h*1000

The burner/boiler matching does not pose
any problem if the boiler is CE type-
approved.
If the burner must be combined with a
boiler that has not been CE type-approved
and/or its combustion chamber dimensions
are clearly smaller than those indicated in
diagram, consult the manufacturer.
The firing rates were set in relation to
special test boilers, according to EN 267
regulations.
The sizes are indicative and dipend on
the configuration, to the combustion
chamber pressure and to the draught.
The values have been taken out from
tests executed with flame tubes.
The dimensions of the flame are made
in test boiler in laboratory without
resistence therefore exists max and
min lenght that take into account the
difference in lenght that comes from the
boiler backpressure.
Example:
Burner thermal output = 8000 kW;
L flame (m) = 5 m (medium value)
D flame (m) = 1 m (medium value)
WARNING: Some flame modifications
can be done in our FLEXSHOP in the
factory in order to shape the flame and
adapt it to some special boiler
or application.
