12 REASONS AND SOLUTIONS OF BOILER BURNER MAL-
FUNCTIONING
One of the causes of non-igniting of the burner may be the mineral-residuals in
the burner chamber. The ignitor cannot work when it comes into contact with the
mineral-residuals because the mineral residuals are non-flammable. If the quality of the
fuel is questionable, it is necessary to clean the combustion tube of the burner regulary
on daily basis. After removing the burner, remove the ash and mineral residue with the
best wire brush or small stick.
Frequent cause of the hoarding is the switching off the burner by the main
switch. Sudden interruption of the air supply (oxygen) to the furnace causes insufficient
combustion of fuel residues. If the burner is ignited again without cleaning it from the
clinker and the ash, the burner can smoke, as the holes might be blocked by the mineral
residues. Therefore the extinguishing process must be carried out before turning off the
power supply of the burner.
In case of more serious faults, contact the installer.
The burner does not ignite the fuel
Causes and service actions:
•
Fuel shortage - Check the hopper and feeder if they are not clogged.
•
Very low starting dose - Check the starting dose.
•
Damaged ignitor - Check the ceramic ignitor.
•
Damaged drive motor - Check engine temperature.
The burner ignites but does not reach the initial power
Causes and service actions:
•
Very large starting fuel amount - Check the starting fuel amount
•
Dirty or non-functional photosensor - Clean or replace the photosensor
Overheating of the internal feeder
Causes and service actions:
•
Burner slapped by a slag
•
Poor chimney draft - use flue gas extraction
•
Clogged boiler heat exchanger or clogged chimney
Damage of the feeder sensor - can not cancel the alarm alert
Causes and service actions:
•
The most common cause of the fault is damage to the thermal protection of the
sensor, which ultimately leads to overheating of the measuring component. If it
is not possible to erase the fault despite cooling the burner, it is necessary to
replace the measuring sensor.
