🔍 Key Concepts

• Boiler safety interlocks in automated systems • How a flame scanner (flame eye) is used to detect flame presence • What the system must do if it thinks there is no flame while fuel is being supplied

💭 Think About

• Think about what the control system "believes" when the flame scanner lens is dirty and cannot properly see the flame. • Ask yourself which choice represents a protective shutdown action rather than a slow performance change. • Consider what function is most critical to prevent a furnace explosion if the flame is not detected.

✅ Before You Answer

• Verify which option describes an automatic safety response rather than a gradual efficiency effect. • Check which choices are directly related to flame detection (not air flow hardware or purge timing). • Confirm how automated burners are designed to react when the system senses a flame failure.
