🔍 Key Concepts

• boiler air heater purpose and how it affects efficiency and metal temperatures • conditions when you might want to reduce heat absorption from flue gas to or from incoming air • operating situations where hot surfaces or ash/soot deposits can be a damage or fire risk

💭 Think About

• Ask yourself: in which option would routing ALL combustion air through the air heater be undesirable or potentially harmful to the equipment? • Which operating condition is most likely to involve heavy soot/ash movement or changing gas paths through the boiler? • Under what circumstance would you deliberately sacrifice some efficiency to protect hardware or maintain safe operation?

✅ Before You Answer

• Identify which choice relates directly to soot/ash movement or deposition around the air heater surfaces. • Consider which options are just normal operating modes where you usually want maximum efficiency from the air heater. • Verify which situation would most likely make you concerned about overheating or burning off soot deposits on hot air‑heater surfaces.
