1.2.2 Use of Heavy Fuel Oil
(1) Purifying of Heavy Fuel Oil
As mentioned above, engines that have been built to run primarily of heavy
fuels will be configured with special components to insure satisfactory
operation. In addition, however, external fuel treatment (purification and
pre-heating) will also be required.
A purifier must be used to remove water and solids from the fuel oil before
it enters the fuel pump. Excess moisture not only reduces the calorific
value (heat energy) of the fuel, but can cause rust and deposit problems on
internal engine components.
(2) Temperature of Heavy Fuel Oil
Suitable atomization of fuel oil is essential for proper operation of the
fuel injection pump and for complete combustion of the fuel/air charge in
the cylinder.
The viscosity of fuel oil as it enters the engine fuel pump should be
between 11.5-16 mm
²
/s at 50
℃
(60-75 Redwood No1.). Viscosity of this level
can be obtained if heavy fuel oil is heated before it enters the fuel
injection pump, as indicated in the Viscosity-Temperature Chart shown in
Figure 1.2-1.
WARNING: Fuel oil temperature must not exceed 145
℃
