Air Regulation On The Combustion Head - baltur TBML 80 ME Bedienungsanleitung

AIR REGULATION ON THE
COMBUSTION HEAD
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 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.
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 aspiration flow from the burner fan. It is recommended to provide
an air closure on the head that requires a noticeable opening of
the air lock that regulates the burner fan intake flow. Obviously this
condition must occur when the burner operates at the maximum
required output. 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.
The above presented adjustments are approximate; position
the combustion head in function of the furnace specifications.
