5. Setting the burner
5.1 Setting the combustion assembly
It may sometimes be necessary to adjust the combustion assembly, i.e. the
position of the brake plate in the burner tube.
5.1.1
Setting the combustion assembly
The burner is equipped with a lever that changes the position of the brake
plate in the combustion head. This is used to set the correct pressure drop
across the combustion assembly and thereby obtain good combustion
without ripples.
The best position is, among other things, dependent on the input power and
overpressure in the boiler.
A general rule of thumb is that the smaller the capacity, the smaller the gap
should be between the brake plate and the combustion assembly.
The position of the brake plate also has an impact on the quantity
of air supplied for combustion. This means that once the brake
plate has been adjusted, the combustion should be checked and,
if necessary, the setting of the air damper adjusted to obtain good
combustion.
Make the adjustment by turning screw X.
A left turn opens the brake plate, providing a lower pressure drop
and more air to the combustion process.
X
A right turn closes the brake plate, providing a higher pressure drop and less
air to the combustion process.
5.2 Setting the air damper
The position of the air damper must be adjusted to achieve a suitable fuel-air
mixture in the operational events that are programmed.
See section (LMV) for the setting procedure.
5.3 Setting the gas damper
The position of the gas damper must be adjusted to achieve the desired
minimum and maximum input power.
See section 13.4 (LMV) for the setting procedure.
