Combustion head adjustment
The air damper servomotor 4)(Fig. 4), beyond varying the air out-
put according to the output demand, through a leverage varies
the combustion head adjustment.
This system allows an optimum adjustment also at minimum fir-
ing rate. Similarly to servomotor rotation, it is possible to vary the
opening of the combustion head moving the tie-rod on the holes
(5-6-7-8-10)(Fig. 15).
The selection of the hole to be used is determined based on the
maximum output requested, as illustrated in Tab. J.
In the factory, the adjustment is adjusted for the maximum stroke
(hole 10, Fig. 15).
