Technical description of the burner
3.8 Firing rates
The maximum output is chosen within area A) of the diagram
(Fig. 2).
The
minimum output must not be lower than the minimum limit
of the diagram.
3.9 Test boiler
The firing rates were obtained in special test boilers, according to
EN 676 regulations. Fig. 3 indicates the diameter and length of
the test combustion chamber.
Example :
Output 756 kW (650 Mcal/h) - diameter 60 cm, length 2 m.
The coupling is ensured when the boiler is EC type-approved; for
boilers or ovens with combustion chambers of very different di-
mensions compared to those shown in the diagram of Fig. 3, pre-
liminary checks are recommended.
WARNING
The firing rate (Fig. 2) was obtained considering a
room temperature of 20°C and an atmospheric
pressure of 1013 mbar (approx. 0 m above sea
level), with the combustion head adjusted as
shown at page 18.
