air regULaTiOn 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. The passage closure increases the pressure upstream of the
disk also with low flow rates. 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 can be indispensable to have
high air pressure upstream of the disc to prevent flame pulsations.
This condition is practically indispensable when the burner works
with a furnace that is pressurized and/or has a high heat load.
From what said above it is evident that the air regulation device on the
combustion head must be set to such position as to always obtain,
behind the disk, a very high air pressure value. 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 shutter that
regulates the suction flow from the burner fan. This must of course
be the case when the burner is working at maximum desired supply.
In practice, start by adjusting the device that closes the air on the
combustion head to an intermediate position, turning on the burner
for a preliminary adjustment as described above.
When the maximum desired flow is reached correct the position
of the device that closes air on the combustion head by moving it
forward or backward so that the air flow is appropriate for the output,
with the air intake shutter lock noticeably open.
X= Head-disc distance; adjust distance X following the below
instructions:
a) slacken 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.
