IRREGULARITY
Defective flame with sparks.
Flame not properly shaped with presence
of smoke and soot.
Defective flame, flickering or protruding
from combustion orifice.
Corrosion inside the boiler.
Soot at chimney outlet.
POSSIBLE CAUSE
1
Spraying pressure is too low.
2
Too much combustion air.
3
Nozzle inefficient because dirty or
worn.
4
Water in the fuel.
1
Insufficient combustion air flow.
2
Nozzle inefficient because dirty or
worn.
3
Nozzle capacity too low with
respect to combustion chamber
volume.
4
Combustion chamber unsuitably
designed or too small.
5
Unsuitable refractory coating (it
reduces excessively the space of
the flame).
6
Boiler or chimney ducts blocked.
7
Spraying pressure is low.
1
Excessive draught, only when
there is an extractor in the
chimney.
2
Nozzle inefficient because dirty or
worn.
3
Water in the fuel.
4
Dirty flame disk.
5
Too much combustion air.
6
Air passage between flame disk
and diffuser excessively closed.
1
Boiler operating temperature too
low (below the dew point).
2
Smoke temperature too low,
approximately below 130 °C for
diesel.
1
Excessive cooling of smoke
(approximately below 130°C)
in the chimney, for an outside
chimney not adequately heat
insulated or cold air infiltration.
REMEDY
1
Restore it at the required value.
2
Reduce combustion air
3
Clean or replace.
4
Drain water from the tank using
a suitable pump. Never use the
burner pump for this purpose.
1
Increase combustion air.
2
Clean or replace.
3
Decrease diesel flow rate to suit
the chamber (thermal power
will obviously be lower than
necessary) or replace the boiler.
4
Increase nozzle flow by replacing
it.
5
Modify it, carefully abiding by
the instructions given by boiler
manufacturer.
6
Arrange for cleaning.
7
Restore it at the required value.
1
Adjust the suction fan speed by
changing the pulley diameter.
2
Clean or replace.
3
Drain water from the tank using
a suitable pump. Never use the
burner pump for this purpose.
4 Clean.
5
Reduce combustion air.
6
Correct the position of the
combustion head regulating
device.
1
Increase the operating
temperature.
2
Increase diesel flow rate is the
boiler allows it.
1
Improve insulation and close any
opening letting cold air into the
chimney.
