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, approxi
-
mately below 130 °C for diesel.
1 Excessive cooling of smoke (approxi
-
mately 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 manu
-
facturer.
6 Arrange for cleaning.
7 Restore it at the required value.
1 Adjust the suction fan speed by chan
-
ging 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 ope-
ning letting cold air into the chimney.
