HEAD ADJUSTMENT DIAGRAM

\\ADJUSTING THE AIR ON THE COMBUSTION
HEAD STARTING UP AND REGULATION
WITH METHANE GAS
The combustion head has an adjustment device so that the air
passage between the disk and the combustion head can be opened
or closed. It is therefore possible 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 gate 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 an 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 gate considerably open.
X= Combustion head-disk distance; adjust the distance X following
the indications below:
• loosen screw 1
• turn screw 2 to position the combustion head 3, referring to
index 4.
• 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
