🔍 Key Concepts

• Boiler combustion safety interlocks and what happens on flame failure • Difference between control functions (efficiency, modulation) and safety shutdown functions • Role of flame scanners/detectors in automatic burner management systems

💭 Think About

• Ask yourself: When a flame scanner no longer detects a flame, what must the system do FIRST to prevent a dangerous condition? • Which option describes a safety shutdown response rather than normal control or start-up action? • Is the flame scanner responsible for starting combustion, optimizing it, or making sure fuel doesn’t continue to flow without a flame?

✅ Before You Answer

• Identify which choices describe safety shutdown actions vs. efficiency or start-up functions • Confirm that with no flame detected, continued fuel flow or forced draft could create an explosive mixture • Eliminate any option where the flame scanner is being used mainly for combustion efficiency control rather than safety interlock
