ADJUSTING AIR ON THE COMBUSTION HEAD
The combustion head has an adjustment device that allows
the air passage between the disk and the combustion head to
be 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 allows greater penetration
into the fuel and therefore excellent mixture and flame stability.
High air pressure upstream of the disk may be necessary to
prevent flame fluctuations, this is particularly essential when the
burner works on the combustion chamber that is pressurized and/
or at a high thermal load.
It’s evident from the above, that the device which closes the air
on the combustion head should be put in such a position as to
always obtain a decidedly high air pressure value behind the disk.
It is advisable to adjust it 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
the 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 shutter opened slightly.
