Heavy Fuel Oil Separator
1. Application of Heavy Fuel Oil Separator
The heavy fuel oil separator is intended for marine and land applications. It is specifically designed for cleaning of mineral oils from water and solid particles (sludge). The cleaned oil is discharged continuously, while the sludge is discharged at intervals.
The separator handles the following types of lubricating oils and low viscosity fuel oils:
Distillate (viscosity 1.5-5.5 cSt/40℃)
Marine diesel oil (viscosity l3 cSt/40℃)
Intermediate fuel oil and heavy fuel oil (viscosity 30-380 cSt/50℃)
Lubricating oil of R & O type, detergent or steam turbine.
The separator can be operated either as a purifier or as a clarifier. When operated as a purifier the separator discharges the separated water continuously.
When the oil contains only small amounts of water the separator is operated as a clarifier, discharging the water together with the solid particles.
The separator has to be installed together with devices for control of its operation.
2. Heavy Fuel Oil Separator Design
The marine oil separator comprises a frame consisting of the frame lower part, the intermediate part and the frame top part with a frame hood.
The separator bowl is driven by an electric motor via a flat-belt power transmission and bowl spindle. The motor drive is equipped with a friction coupling to prevent overload.
The bowl is of disc type and hydraulically operated at sludge discharges. The hollow bowl spindle features an impeller which pumps closing water from a built-in tank to the operating system for sludge discharge.
The main inlets and outlets are shown with their connection numbers in the illustration.
3. Heavy Fuel Oil Separator Outline of Function
The separation process takes place in the rotating bowl. Unseparated oil is fed into the bowl through the inlet. The oil is cleaned in the bowl and leaves the separator through the outlet via a paring chamber. Impurities heavier than the oil are collected in the sludge space at the bowl periphery and removed automatically at regular intervals.
There are no contacting surfaces between process rotating parts and stationary parts (inlet, outlet, feed devices), and the interfacing surfaces are not sealed. As the separation process is carefully balanced regarding pressures and fluid levels, any leakages will not occur as long as the correct running conditions are maintained.
