🔍 Key Concepts

• auxiliary boiler ignition sequence (purge, fuel admit, spark, flame detection) • role of electrodes and spark gap in establishing ignition • difference between faults that prevent ignition vs. faults that cause unsafe fuel accumulation

💭 Think About

• Which option directly interferes with creating a reliable spark or flame at the burner tip, before combustion has started? • Which options would more likely lead to a potential furnace explosion or unsafe condition rather than a simple failure to light off? • Think about what condition the boiler safety system is designed to detect and shut down for if ignition does not occur within the trial-for-ignition time.

✅ Before You Answer

• For each choice, ask: does this problem stop the spark/flame from forming, or does it cause too much fuel in the furnace? • Consider which items would typically cause a safety trip after ignition failure, versus which one is a root cause of the burner not lighting. • Verify how electrode condition and fuel pressure affect atomization, spark gap, and ignition reliability in auxiliary boiler manuals.
