🔍 Key Concepts

• Burner management system (BMS) purpose and normal automatic protections • Difference between AUTO (automatic) and HAND/MANUAL modes of operation • Role of safety interlocks and trips in boiler operation

💭 Think About

• Think about what the BMS normally does for you automatically in AUTO mode that you, as the operator, must take more responsibility for in HAND mode. • Consider whether HAND mode increases or decreases reliance on automatic safety devices and interlocks. • Ask yourself: in HAND firing, which functions are most likely to be partially or fully taken out of the automatic control loop?

✅ Before You Answer

• Verify which functions are always required for safety (for example, flame failure protection) regardless of operating mode. • Consider whether HAND mode would make burner sequence control more or less automatic. • Think carefully about which item, if lost or altered in HAND mode, would represent a significant safety limitation, not just a performance or convenience issue.
