AIR REGULATION ON THE COMBUSTION HEAD
The combustion head has a regulation device that allows the air
passage between the disc and the combustion head to be opened or
closed. Closing the passage, you can obtain high pressure upstream
of the disc even at low flow rate. 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 disc may be necessary to prevent flame fluctuations, this is
particularly essential when the burner works on the combustion
chamber that is pressurised and/or at a high thermal load.
CAUTION / WARNING
Check that the combustion head is centred with respect to the
disk. An imperfect centring could cause a poor combustion and
overheating of the head with its subsequent rapid deterioration.
CAUTION / WARNING
The above adjustments are indicative only; position the
combustion head according to the characteristics of the
combustion chamber.
