Heavy Oil Fuel System from Bunker Tanks to Engine.
Fuel is
pumped from the Fuel Oil Double Bottoms via a Transfer Pump to a Fuel Oil
Settling Tank where it is heated.
The
Fuel Oil Purifiers/Centrifuges take suction from the Settling Tank via Purifier
Heaters, pass through the Purifiers, where any water and impurities are removed
and passed on to the Service Tank which also has a set of Heating Coils.
From the
Service Tank the Fuel then passes via a Flowmeter to the Mixing Tank, from
where the Booster Pumps take suction, discharging to the Fuel Oil Heaters,
where the correct Fuel Oil Temperature/Viscosity is achieved for correct Fuel
Combustion in the Engine.
The Fuel then
passes through the Viscosity Regulator which controls the Heater Temperature,
then on to the Fuel Oil Filters (which are heated), to the Fuel Pumps, then to
the Fuel Injectors via Double Skin/Wall High Pressure Pipe.
Any
surplus Fuel returns via a Regulating Valve from the Fuel Pumps back to the
Mixing Tank.
Diesel Oil
can also be used in the System and is fed to the System via a three-way valve.
When Diesel is used, no
heating is required
