Combustion Head Air Adjustment - baltur TBG 55ME Mode D'emploi

COMBUSTION HEAD
AIR ADJUSTMENT
The combustion head has an adjustment
device so that the air passage between
the disk and the combustion head is
opened or closed. You are thus able
to obtain, 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. It may be necessary
to have high air pressure before the
disk to prevent flame fluctuations,
particularly essential when the burner
works on the combustion chamber 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 blast-pipe must
be set at a position such as to always
obtain very high air pressure behind
the disk. 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 damper
that regulates the aspiration flow from
the burner fan. This must of course be
the case when the burner is working at
maximum desired 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 desired supply
has been reached, the position of
the device that closes the air at the
combustion head is corrected, moving
X= Distance between combustion head and disk; adjust the distance X following the indications below:
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.

N.B. The above adjustments are indicative only; position the combustion head according to
the characteristics of the combustion chamber
it forward and backwards, until the right
amount of air is flowing to the supply,
with the air damper in significantly
open.
