🔍 Key Concepts

• Automatically fired auxiliary steam boilers – what conditions must cause the burner to shut down for safety • Where a stack (uptake) temperature sensing device is located and what it is actually measuring • Differences between flame failure protection, low-water protection, and feed pump/pressure protection

💭 Think About

• Ask yourself: What change in the stack would be detected FIRST if the burner stopped burning properly, but fuel was still being supplied? • Which of the listed events would most directly and quickly show up as an unusual stack temperature pattern rather than a pressure or water-level change? • Consider what specific accident or unsafe condition the designer wants to prevent by watching the temperature in the stack, not in the boiler drum or feed system.

✅ Before You Answer

• Match the device location: a sensor in the stack will mainly detect changes in exhaust/flue gas temperature, not water level or pump pressure. • Review typical boiler safety systems: low-water cutout, feed pump pressure switches, and flame scanners/temperature devices — which one belongs where? • Decide which choice best connects a change in stack temperature with an immediate need to shut off fuel to the burner to prevent damage or unsafe conditions.
