🔍 Key Concepts

• flash point of a fuel and why it matters for safety • difference between heating value (energy content) and sulfur content • effects of sulfur in fuel oil on engines and the environment

💭 Think About

• Which fuel property improves fire safety on board: a higher flash point or a lower flash point? • For efficient operation, do you want a fuel that contains more energy per unit mass (high heating value) or less energy (low heating value)? • Is higher sulfur content generally desirable or something operators try to reduce, and why?

✅ Before You Answer

• Make sure you know that a higher flash point generally means safer handling and storage. • Confirm that a high heating value means more energy from the same amount of fuel. • Recall that sulfur content is linked to corrosion and air pollution and is limited by regulation.
