🔍 Key Concepts

• How a purifier/centrifuge separates water and solids from heavy fuel oil • Effect of flow rate on separation time inside the bowl • Effect of viscosity on fuel’s ability to separate into layers under centrifugal force

💭 Think About

• If the fuel moves through the centrifuge faster, what happens to the time available for water and solids to separate out? • How does higher or lower viscosity change the ease with which fuel, water, and sludge can form distinct layers in the bowl? • Think about manufacturer guidance: what operating parameters are normally controlled or adjusted when setting up a fuel oil purifier?

✅ Before You Answer

• Verify whether flow rate affects separation efficiency and clarity of purified fuel • Verify whether viscosity is something engineers adjust (for example, by heating) before or during centrifuging • Check if both, one, or neither of these factors are considered critical operating parameters for heavy fuel oil purification
