Quick Answer: What Is Fuel Oil Purifier?

What is the use of fuel oil purifier?

How does a fuel oil purifier work?

An oil purifier uses the same principle for separating dirt or water from oil. Instead of using gravity, it uses centrifugal force. Through a system of gears, a centrifuge bowl is rotated at high speeds. Oil to be purified is allowed to enter the bowl while it is rotating.

How do you stop the oil from the fuel purifier?

Stopping of Purifiers:

  1. De-sludge the purifier after stopping the feed inlet.
  2. Shut down the steam inlet to the oil.
  3. Stop the purifier after filling up the bowl with water.
  4. Apply brakes and bring up the purifier to complete rest.

What are the parts of fuel oil purifier?

The main component of purifier is correct size gravity disc or dam ring which is responsible for creating an interface between the oil and water. 2) Clarifier: When a centrifugal is arranged to remove only impurities and a small amount of water, it is called as the clarifier.
