Fuel oil heater
The heater is to be of the tube or plate heat ex-
changer type.
The required heating temperature for different oil
viscosities will appear from the ‘Fuel oil heating
chart’. The chart is based on information from oil
suppliers regarding typical marine fuels with vis-
cosity index 7080.
Since the viscosity after the heater is the control-
led parameter, the heating temperature may vary,
depending on the viscosity and viscosity index of
the fuel.
Recommended viscosity meter setting is 05 cSt.
Fig. 7.05.01: Fuel oil heating chart
Fuel oil viscosity specified ... up to 700 cSt at 50°C
Fuel oil flow .................................... see capacity of
fuel oil circulating pump
Heat dissipation ..................see ‘List of capacities’
Pressure drop on fuel oil side ........maximum bar
Working pressure ..........................................0 bar
Fuel oil inlet temperature .................approx. 00 °C
Fuel oil outlet temperature ........................... 50 °C
Steam supply, saturated ..........................7 bar abs
To maintain a correct and constant viscosity of
the fuel oil at the inlet to the main engine, the
steam supply shall be automatically controlled,
usually based on a pneumatic or an electrically
controlled system.
