Adjusting The Air On The Combustion Head - baltur TBG 85 P Manual De Instrucciones

ADJUSTING THE AIR ON THE COMBUSTION HEAD

The combustion head is equipped with a regulation device, so as to
open or close the air passage between disk and head. 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. 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.
From what said above it is evident that the device closing the air
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 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, 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 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.
X = Head-disc distance; adjust distance X following the below
instructions:
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.
