The separator is the principle component of a number of high-efficiency heavy fuel oil separation systems in the ship. Untreated oil that is heated to the correct temperature is fed continuously to the separator so that impurities can be cleaned. After centrifugal separation, cleaned oil is continuously pumped away and separated sludge as well as water accumulate at the bowl periphery.
A water transducer in the clean oil outlet measures the capacitive resistance and signals changes to a control unit. Depending on the water content, the control unit either opens the drain valve or expels the water through the bowl discharge ports during sludge discharge.
