🔍 Key Concepts

• automatic combustion control systems on marine boilers • how a flame scanner or flame detector proves flame within a set time • what happens in the safety shut‑down sequence when flame is not proven quickly or is unstable

💭 Think About

• Which component in this system actually decides whether to keep the burner firing or to shut the fuel off after a second or two? • If the flame is lighting but then going out in about two seconds, is that more likely a problem with fuel getting to the burner, or with the system detecting the flame? Why? • Look at each choice and ask: would this fault prevent initial ignition, prevent fuel from staying on, or prevent the controller from sensing a stable flame?

✅ Before You Answer

• For each option, decide whether it would allow initial ignition to occur at all. • Think about which fault would cause the control to repeatedly shut the burner very quickly after light‑off (about 1–2 seconds), as if no flame were detected. • Verify which component interacts directly with the flame detection circuit (scanner, sensor, or its viewing path) rather than with fuel temperature or valve power.
