🔍 Key Concepts

• How heat transfer in a boiler is affected by dirty heating surfaces versus structural damage • The relationship between stack gas temperature and overall boiler efficiency • Which conditions cause more heat to go up the stack instead of into the water/steam

💭 Think About

• Which of these choices would most directly reduce heat transfer from the hot gases to the water, causing the flue gases to stay hotter? • Is a gradual, long-term rise in stack temperature more likely from fouling/insulation problems, or from casing leakage to the outside air? • For each option, ask: does this problem keep heat in the gas path, or does it let heat escape somewhere else?

✅ Before You Answer

• Identify which options describe fouling of heat-transfer surfaces compared to mechanical damage or leakage • Decide which condition would most likely cause a consistent increase in stack gas temperature, not just a localized issue • Consider normal boiler troubleshooting practice: what is the first thing you check when stack temperature is running higher than usual?
