🔍 Key Concepts

• how boiler firing rate is controlled and what keeps it from getting too hot or over-pressurized • the difference between a condition that LIMITS firing vs. one that REDUCES combustion efficiency • which devices are specifically intended as safety shutdowns or high-limit protections

💭 Think About

• Ask yourself: which option, if it fails, would allow the burner to keep firing when it SHOULD have shut down? • Consider which choices mostly affect burner performance (poor spray, bad flame) versus which directly control maximum temperature or pressure. • Think about normal boiler safeties: what components are designed to stop firing when water or temperature reaches a set point?

✅ Before You Answer

• Identify which item is a safety control whose job is to stop the burner at a preset limit. • Separate problems that cause poor or no flame from problems that cause too much heat input. • Confirm which condition would let firing CONTINUE beyond safe temperature/pressure rather than shutting the burner down.
