🔍 Key Concepts

• Automatic boiler safety shutdown systems in unattended/automated plants • How flame scanners/flame failure detectors protect fuel supply to burners and headers • Difference between local burner protection and plant-wide fuel shutoff

💭 Think About

• Ask yourself: if BOTH boilers lose flame, does the system just shut each burner, or does it protect the entire fuel supply feeding them? • Which device(s) must close to prevent fuel continuing to be supplied to a boiler with no flame present? • Is the main turbine throttle valve directly part of the boiler flame‑failure safety chain, or is it controlled by other parameters like steam pressure and load?

✅ Before You Answer

• Verify which solenoids are directly interlocked with flame failure (burner level vs main fuel header). • Consider what must happen to prevent fuel accumulation in furnaces after total flame loss. • Think about whether the turbine steam valve is a fuel‑safety device or a load/steam control device.
