02.1.2 Fuel treatment
02.1.2.1
Purification
Heavy fuel (residuals, and mixtures of residuals and distillate) must
be purified in an efficient centrifuge before entering the day tank.
The fuel is to be heated before centrifuging.
Recommended temperatures, depending on the fuel viscosity,
are stated in the diagram, chapter 02, Fig 02-1.
Be sure that the correct gravity disc is used. Never exceed the flow
rates recommended for the centrifuge for the grade of fuel in use.
The lower the flow rate the better the efficiency.

Note! Recommended centrifuge flow rates, see separator manufacturers
instruction manual.
In case pure distillate fuel is used, centrifuging is still recommended
as fuel may be contaminated in the storage tanks.
Rated capacity of the centrifuge may be used provided the fuel
viscosity is less than 12 cSt at centrifuging temperature.
Marine Gas Oil viscosity is normally less than 12 cSt at 15 °C.
02.1.2.2
Heating
See diagram, Fig 02-1. Keep the fuel temperature about 10 °C above
the minimum storage temperature indicated in the diagram in order
to minimize the risk of wax formation, and the temperature after the
final heater 5 - 10 °C above the recommended temperature before
injection pumps to compensate for heat losses between heater and
engine.
