🔍 Key Concepts

• Flash point vs. fire point vs. auto-ignition temperature of fuel oils • Purpose of heating heavy fuel oil before combustion (viscosity and atomization) • Where it is most dangerous to have fuel above its flash point (storage/transfer vs. at the burner)

💭 Think About

• Ask yourself: In which part of the fuel system would fuel above its flash point create the greatest fire/explosion risk? • What is the main reason engineers heat heavy fuel oil just before it enters the burners on a boiler? • Which option describes a normal, controlled operating condition rather than an emergency or abnormal situation?

✅ Before You Answer

• Verify which options involve fuel handling/transfer versus fuel preparation for combustion • Consider which choice matches the need for proper viscosity and atomization of heavy fuel oil • Eliminate any option that suggests exceeding flash point for reasons other than combustion requirements
