in series. Alternatively the main and stand-by separators may
be run in parallel, but this makes heavier demands on correct
gravity disc choice and constant flow and temperature con-
trol to achieve optimum results. Flow rate through the centri-
fuges should not exceed the maximum fuel consumption by
more than 10 %.
·
Sufficient heating capacity to keep centrifuging and injection
temperatures at recommended levels. It is important that the
temperature fluctuations are as low as possible (
±
2 °C before
centrifuge) when centrifuging high viscosity fuels with densities
approaching or exceeding 991 kg/m
3
at 15 °C.
·
Sufficient preheating of the engine and the fuel systems before
starting the engine.
·
Keeping fuel injection equipment and the inverse cooling
system in good condition.

It is recommended to use in the first place BN 50-55 lubricants when
operating on heavy fuel. This recommendation is valid especially
for engines having wet lubricating oil sump and using heavy fuel
with sulphur contents above 2.0 % mass. BN 40 lubricants can be
used when operating on heavy fuel as well if experience shows that
the lubricating oil BN equilibrium remains at an acceptable level.
