🔍 Key Concepts

• Behavior of burners and atomization when fuel supply is restricted • Common causes of fires beginning to sputter in a boiler or incinerator system • Normal operator actions when there is indication of air or restriction on the suction side of the fuel system

💭 Think About

• What does it usually mean when a steady flame starts to sputter – is fuel flow becoming more steady or less steady? • If the problem is on the suction side of the fuel system (like air leaks or clogged strainers), which actions would make that problem worse, and which would bypass or remove the restriction? • Which option is most consistent with restoring a clean, steady fuel flow to the burners rather than forcing fuel through a possible restriction?

✅ Before You Answer

• Consider what manifold pressure controls in a burner fuel system and whether changing it fixes suction problems or just masks symptoms. • Think about how a duplex strainer is used in operation and what problem it is meant to address. • Ask whether taking suction from another settling tank would quickly correct a sputtering flame if the real problem is on the strainers or manifold rather than the tank itself.
