ADJUSTING THE AIR ON THE
COMBUSTION HEAD
The combustion head has an adjustment device so that
the air passage between the disk and the combustion
head can be opened or closed. You are thus able to
obtain, by 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. High air pressure upstream of the disk
may be necessary to prevent flame fluctuations, this
is particularly essential when the burner works on the
furnace that is pressurised and/or at a high thermal load.
It is clear from the above that the device that closes the
air to the combustion head must be set at a position
such as to always obtain very high air pressure 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 shutter that
regulates the suction flow from the burner fan. This must
of course be the case when the burner is working at the
required maximum 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 required maximum supply has been
reached, the position of the device that closes the
air at the combustion head has to be corrected,
moving it forward and backwards, in order to obtain
an air flow suitable for the supply with the air shutter
considerably open.

COMBUSTION HEAD ADJUSTMENT DIAGRAM

X= Combustion head-disk distance; adjust the distance X following
the indications below:
a) loosen screw 1
b) turn screw 2 to position the combustion head 3, referring to
index 4.
c) adjust the distance X between minimum and maximum
according the indications in the table.
The above adjustments are indicative only; position the
!
combustion head according to the characteristics of the
combustion chamber
