Under which of the following conditions must the combustion control system for a small automatic auxiliary boiler secure the burner?

🔍 Key Concepts

• Purpose of an automatic combustion control system on a boiler • What condition would create an immediate unsafe firing situation in the furnace • Difference between an operating condition that is "abnormal" vs. one that is directly hazardous to ignition and combustion

💭 Think About

• Ask: Which option, if it occurred while the burner is firing, would make it unsafe to continue supplying fuel to the furnace even for a few seconds? • Consider which conditions are usually handled by regulating or modulating the system, and which conditions require an emergency shutdown of the burner. • Think about what happens inside the furnace and boiler if the flame is not properly maintained while fuel is still being delivered.

✅ Before You Answer

• Identify which choice is directly related to loss of proper combustion in the furnace. • Eliminate any options that are normally controlled by pressure or level regulators rather than a burner safety trip. • Verify which condition would be detected by a flame scanner/safety device rather than by pressure or temperature instruments.
