TYPE OF IRREGULARITY
Defective flame with sparks
Flame badly shaped with smoke and
soot
Defective flame, pulsating or
escaping from the combustion
stokehole
Corrosion inside the boiler
Soot at the chimney exit
INSTRUCTIONS FOR DETERMINING THE CAUSE LEADING TO
IRREGULARITIES IN THE OPERATION OF LIGHT OIL
BURNERS, AND THEIR ELIMINATION
POSSIBLE CAUSE
1) Atomizing pressure too low
2) Excessive combustion air
3) Inefficient nozzle, either fouled or worn out
4) Water in the fuel
1) Insufficient combustion air
2) Inefficient nozzle, either fouled or worn out
3) Combustion chamber unsuitable or too
small
4) Delivery nozzle inadequate with respect to
the combustion chamber volume
5) Refractory lining unsuitable or excessive
6) Boiler or chimney ducts clogged
7) Low atomizing pressure
1) Excessive draught (only when there is an
aspirator in the chimney).
2) Inefficient nozzle, either dirty or worn out.
3) Water in the fuel
4) Dirty disk
5) Excessive air combustion
6) Air passage between disk and head closed
too much
1) Boiler operating temperature too low (below
dew point)
2) High sulphur content in the fuel
3) Smoke temperature too low (below 180° C)
1) Excessive cooling (below 180 °C) of smoke
before exit, insufficient insulation for an
outside chimney or cold air infiltration
1) Re-set it at the required rating
2) Reduce combustion air
3) Clean or replace it
4) Drain the fuel from the cistern using a proper
pump. (Never use the burner pump for this job).
1) Increase combustion air
2) Clean it or replace it
3) Modify or reduce the nozzle delivery to suit the
combustion chamber or replace the boiler
4) Increase nozzle delivery by replacing it
5) Modify it or make it lighter according to boiler
manufacturer's instructions
6) Clean them
7) Re-set at required value
1) Adjust the aspirator speed by modifying the
diameter of the pulleys
2) Clean it or replace it
3) Drain the cistern using a proper pump (never
use the burner pump for this job).
4) Clean it.
5) Reduce air combustion
6) Correct the position of the combustion head
regulation device
1) Increase operating temperature
2) Change the type of fuel
3) Increase the nozzle delivery by replacing it
1) Improve insulation and close any gaps that can
let cold air in
