🔍 Key Concepts

• Function of a flame safeguard in an automatically fired boiler • Difference between sensing flame presence vs sensing temperature or draft • Which devices listed are used to detect light from a flame rather than just heat or flow

💭 Think About

• Ask yourself: does a flame safeguard need to know that there is actual flame/light present, or just that there is heat somewhere in the system? • Which of these devices is commonly used in burner management systems to shut off fuel quickly if the flame goes out? • Which option is designed specifically to respond to radiant energy from a flame rather than slower changes in temperature?

✅ Before You Answer

• Identify which choices are primarily temperature-sensitive devices vs light-sensitive devices • Think about which device can react very quickly to a flameout to prevent fuel accumulation • Verify which device is typically mounted with a line-of-sight to the burner flame in large automatic boilers
