🔍 Key Concepts

• Heavy fuel oil properties when heated (what happens to viscosity and vapor formation) • How purifier bowls and seals are affected by temperature and pressure • Why manufacturers specify a maximum preheat temperature before purification

💭 Think About

• Think about what happens to heavy fuel oil as temperature rises: which of the listed problems becomes more likely, and which actually become less likely? • Which of the four options would a manufacturer most want to avoid to protect the purifier’s internal parts and maintain separation efficiency? • Consider which issues are normally controlled by design (like pressure limits) versus those directly affected by oil temperature at the purifier inlet.

✅ Before You Answer

• Compare how viscosity changes with temperature and ask: would higher temperature make the oil thicker or thinner? • Consider whether heavy fuel oil at 80–95°C is likely to be within an explosive range under normal purifier operating conditions. • Think about which components inside a purifier are temperature-sensitive materials and might deform or lose effectiveness if overheated.
