🔍 Key Concepts

• Relationship between stack temperature and combustion efficiency • Effect of excess air on how much heat goes up the stack • Which systems actually influence the flue gas path (furnace, tubes, uptake) vs those that don’t

💭 Think About

• Ask yourself: which choice directly affects the temperature and characteristics of the flue gases leaving the boiler? • Which options are mainly about pressure in other systems (fuel or feedwater) and would have only indirect or minimal effect on stack temperature? • Which condition would cause more heat to be carried away in the exhaust instead of being absorbed into the water/steam system?

✅ Before You Answer

• Identify which answers are directly related to the combustion process and air–fuel mixture • Eliminate any answers that only change pressure in a separate system (fuel or feedwater) without a clear path to changing flue gas temperature • Consider which condition is commonly associated with increased stack losses and reduced boiler efficiency
