ADJUSTING AIR ON THE COMBUSTION
HEAD
The combustion head is equipped with an adjustment device, so
as to open or close the air passage between disk and head. By
closing the passage, it is thus possible to obtain a high pressure
upstream of the disk also for low flow rates. The high air speed
and turbulence allows a better penetration of the same 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 pressurized 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 flow from the burner fan output.
This must of course be the case when the burner is working at
the maximum required 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 required supply is reached, correct the
position of the device closing the air on the combustion head by
moving it forwards or backwards (0002934190) so as to have a
suitable air flow for the supply, with suction air adjustment shutter
sensibly open.
!
To make adjustment of the combustion head easier,
you are advised to consult tables (dwg 0002935000 for
BTG 15ME, dwg 0002934171 for BTG 20ME and dwg
0002935180 for BTG 28ME).
When reducing the air passage on the combustion head, avoid
closing it completely, which may cause an excessive heating of the
head with a consequent quick deterioration.
