🔍 Key Concepts

• the purpose of using diesel oil versus heavy fuel oil in boiler burners • how boilers are started up on a cold ship versus when already in service • the characteristics of atomization, ignition quality, and viscosity of different marine fuels

💭 Think About

• Think about which fuel is easier to ignite and burn cleanly when the boiler and fuel systems are not yet warm. • Consider when you would want a low‑viscosity, good‑ignition fuel in order to avoid problems like poor atomization or flame failure. • Ask yourself in which of these options the boiler and fuel system conditions make it hardest for a heavy fuel to burn properly without help.

✅ Before You Answer

• Which option describes a situation where heavy fuel oil would be least suitable by itself? • Which condition requires good ignition quality at low temperature and reliable flame stability? • Eliminate any choices that describe conditions where the boiler and fuel are already hot and stable, or where the issue could be corrected by adjusting combustion settings instead of changing fuel.
