FUEL OIL TREATMENT- Problem and Solution Summary
Problem
Solution
Fuel sludging
High water content and fuel polymerisation
causes sludge formation and filter blocking.
Inhibit polymerisation and disperse sludge in

to combustible state. Demulsify water and
stabilise fuel to restore combustion
characteristics.
High temperature corrosion

A combination of vanadium and sodium
results in highly corrosive ashes with low
melting
points whichcorrosion
attack metals causing
Low temperature
Raise the melting point of the ashes to keep

them as solids. The ashes are then ejected
with the exhaust gas.
Sulphur and high levels of excess air

contribute to the formation of diluted
sulphuric acid leading to corrosion.
A combustion catalyst enables the reduction of

excess air in boilers and reduces the formation
of sulphuric acid. In diesel engines the use of
ash
modifiers inhibits the catalytic action that
vanadium has on the SO2->S03 conversion.
Ash deposits
Carbon residuals from combustion processes
bind ash particles together to form deposits.
Combustion catalyst increases C->CO2

conversion reducing free carbon.
Smoke and Smut Emission

Low excess air; pre-heat temperatures too
high:burner/injector malfunction; fouled air
coolers;incorrect timing; high MCRfuel,
resulting in excessive carbon residue.
Deterioration of power output
Check and adjust mechanical functions e.g.clean air cooler. A combustion catalyst will
reduce carbon residue formation.
Ash and carbon deposits in combustion zone

and exhaust system causing general loss of
efficiency in boilers and turbocharger surging
in diesel engines.
Combustion catalysts improve combustion.

Ash modifiers reduce deposits.
