COMBUSTION HEAD AIR ADJUSTMENT

The combustion head has an adjustment device so that the air
passage between the disk and the combustion head is opened
or closed. You are thus able to obtain, closing the passage, high
pressure upstream of the disk even at low capacity. The high speed
and turbulence of the air provides for its greater penetration into the
fuel and therefore an excellent mixture and flame stability. It may
be necessary to have high air pressure before the disk to prevent
flame fluctuations, particularly essential when the burner works
on the combustion chamber that is pressurized and/or at a high
thermal load.
It is clear from the above that the device that closes the air to the
blast-pipe must be set at a position such as to always obtain very
high air pressure behind the disk. It is advisable to adjust in such
a way as to obtain a closure of the air at the combustion head that
will require a significant opening of the air damper that regulates the
aspiration flow from the burner fan. This must of course be the case
when the burner is working at maximum desired supply.

In practice you have to start the adjustment with the device that
closes the air at the combustion head in an intermediate position,
switching on the burner for approximate adjustment as explained
previously.
When the maximum desired supply has been reached, the position
of the device that closes the air at the combustion head is corrected,
moving it forward and backwards, until the right amount of air is
flowing to the supply, with the air damper in significantly open.
