Combustion head adjustment
In order to optimise performance, the burner is equipped with a
variable geometry combustion head which operates on the basis
of the delivered output.
According to the same rotation of the air servomotor, it is possible
to change the combustion head opening by moving the
lever 2)(Fig. 18) on the holes (1-2-3-4-5-6), after loosening the
screw 1). The choice of the hole (1-2-3-4-5-6) to use is based on
the following table, according to the required output.
These output values may not match with the actual values as the
combustion conditions change according to the plant.
The factory regulation corresponds to the minimum output (cou-
