🔍 Key Concepts

• 46 CFR requirements for automatic auxiliary boilers • Purpose of a pre-purge in boiler operation (clearing the furnace of combustible vapors) • Relationship between air changes and safe removal of unburned fuel or vapors

💭 Think About

• Why does the Coast Guard require a minimum number of air changes before ignition in an automatic boiler? • How many air changes would reasonably ensure the furnace is safely cleared of residual fuel or vapors without causing unnecessary delay? • Think about industry-standard boiler safety practices—what is the commonly referenced minimum purge for automatic firing?

✅ Before You Answer

• Confirm the exact wording in 46 CFR that addresses pre-purge requirements for small automatic auxiliary boilers. • Verify that the required number of air changes is the minimum purge prior to ignition, not during normal running. • Ensure you are not confusing requirements for larger main propulsion boilers with those for small automatic auxiliary boilers.
