🔍 Key Concepts

• Automatic combustion control systems on modern boilers • Purpose of a flame safeguard / flame failure device • Difference between monitoring and regulating in control systems

💭 Think About

• In a boiler control system, what specific safety risk happens if the burner flame unexpectedly goes out while fuel is still being supplied? • Which component in a combustion system actually adjusts fuel pressure or air flow, and which component’s main job is only to detect a condition? • Think about the word "scanner" – is it more likely to directly control flows or to detect whether something is present or within limits?

✅ Before You Answer

• Identify which choice describes a device whose main job is to detect flame presence/quality rather than to move valves or dampers • Eliminate any options that describe regulating or directly adjusting fuel or air, instead of sensing conditions • Confirm that the remaining option matches a typical flame safeguard sensor used to shut down the burner if unsafe conditions occur
