FIRING RATES (A)
The TECNO 34-L & TECNO 44-L model burners
can work in two ways: one-stage and two-
stage.
1st stage OUTPUT
must be selected within
area A of the adjacent diagrams.
2nd stage OUTPUT
must be within area B. This
are supplies the maximum output of the burner
according to the pressure in the combustion
chamber.
The work point may be found by plotting a verti-
cal line from the desired delivery and a horizon-
tal line from the pressure in the combustion
chamber The intersection of these two lines is
the work point which must lie within area B.
Attention:
The FIRING RATE area values have been
obtained considering a surrounding temperature
of 20 °C, and an atmospheric pressure of 1013
mbar (approx. 0 m above sea level) and the
combustion head adjusted as shown on page 7.
TEST BOILER (B)
The firing rate was set in relation to special test
boilers in accordance with the methods defined
in EN 267 standards.
Figure (B) indicates the diameter and length of
the test combustion chamber.
Example
Output 35 kg/hour:
diameter = 50 cm; length = 1.5 m.
Whenever the burner is operated in a much
smaller
commercially-available
combustion
chamber, a preliminary test should be per-
formed.
