4.10 Combustion head setting
In addition to varying air flow depending on the output request-
ed, the air gate valve servomotor 4) (Fig. 5) by means of a lifting
assembly - varies the setting of the combustion head.
This system allows an optimal setting even at a minimum firing
rate. For the same servomotor rotation, combustion head open-
ing can be varied by moving the tie rod onto holes 5-6-7, Fig. 15.
When dealing with boilers featuring a strong back pressure, if air
delivery is insufficient even with the damper fully open, you can
use a different setting shows in the following table do this by
moving the tie rod onto the next highest hole numerically speak-
ing, thus increasing the combustion head’s opening and hence
air delivery.
