🔍 Key Concepts

• Ultraviolet (UV) flame detection vs. infrared/visible light detection • How boiler burner flame shape and location affect a flame scanner’s field of view • What conditions in a furnace (like hot brickwork or multiple burners) might cause false signals

💭 Think About

• Think about what makes UV flame scanners different from detectors that respond to visible glow or heat. Which choice reflects something unique about UV detection? • Which option best prevents a false flame indication when there is no actual flame at the burner tip? • Consider how a scanner on an automated boiler must behave to safely shut down the fuel if the flame at a specific burner is lost. Which choice supports that safety function most directly?

✅ Before You Answer

• Compare which options could cause false positives (indicating a flame when it’s not actually present at the burner). Eliminate those. • Ask: does the scanner need to see the entire furnace or the flame from a specific burner for safe operation? • Verify which option aligns with UV’s tendency to detect the most intense, specific part of combustion, rather than general heat or visible glow.
