ADJUSTING AIR ON THE COMBUSTION HEAD
The combustion head is equipped with a device that automatically
regulates the passage between the diffusor disk and the head, ad -
mitting combustion air to the head. This passage can be restricted
to obtain high pressure upstream of the diffusor disk, even with low
fuel throughput, so that high velocity and turbulence ensure that the
air penetrates the gas more thoroughly, giving an optimum fuel/air
mixture and a stable flame. With gas burners, it can be essential to
have high air pressure on the diffusor inlet side if pulsation of the fla -
me is to be prevented, especially where the burner operates in a high
pressure combustion chamber, or in high thermal load conditions.
Accordingly, the head must be adjusted in such a way that a sub -
stantially high pressure is always generated upstream of the diffusor.
It is recommended that the passage of air allowed through to the
head be restricted in such a way that there is a generous opening
of the air shutter regulating the air flow supplied by the burner fan.
To achieve this, adjust the screws on the modulation disk.
When the regulation is complete, remember to tighten the screws
locking the regulator screws.
