🔍 Key Concepts

• 46 CFR requirements for oil-fired main boilers with automatic safety control systems • Purpose of a flame detector in boiler safety (shutoff on flame failure) • Difference between monitoring each burner vs. monitoring the entire furnace

💭 Think About

• Ask yourself: In an automatic system, what must happen immediately if the burner flame is lost? What device makes that possible? • Consider whether safety is better assured by watching each individual burner or just the general furnace area. • Think about which options describe control/sensing of steam and temperature versus direct detection of flame—which is more critical for automatic safety shutdown?

✅ Before You Answer

• Verify in 46 CFR that automatic safety controls for oil‑fired boilers require flame failure protection. • Check whether the regulation specifies coverage per burner or only per furnace. • Confirm that devices like pressuretrols and pyrostats control pressure/temperature, not directly detect flame presence.
