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 the minimum
firing 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. 19).
