🔍 Key Concepts

• 46 CFR requirements for automatic auxiliary boiler fuel ignition systems • Differences between continuous pilot ignition and one-time ignition sources • Safety considerations for unattended or automatic boiler operation

💭 Think About

• Which ignition methods can reliably re‑ignite the burner automatically after a flameout without manual intervention? • Which options are commonly associated with stable, controlled flame supervision in marine boiler practice? • Which methods would regulators likely view as unsafe, unreliable, or impractical for automatic operation on a shipboard boiler?

✅ Before You Answer

• Confirm in 46 CFR that automatic boilers need an ignition source suitable for repeated, automatic light‑offs • Check which options can be continuously maintained and monitored during operation • Eliminate any methods that sound like manual, impact, or emergency-only igniters rather than standard automatic boiler practice
