Which of the conditions listed would indicate excessive soot buildup on the economizer?

Question 1 of 27070

Which of the conditions listed would indicate excessive soot buildup on the economizer?

🔍 Key Concepts

• Effect of soot on heat transfer surfaces (like an economizer) • Relationship between soot buildup and gas-side draft/air flow • How soot affects temperatures and pressures in the boiler and uptake

💭 Think About

• Think about what happens to the gas flow path when soot builds up on the economizer tubes. Does it become easier or harder for gases/air to move? • If gases cannot pass freely through the economizer, what happens to the pressure on the furnace side of the gas path? • Which listed condition would you expect if the path for combustion gases is partially blocked by soot deposits?

✅ Before You Answer

• Identify which choice reflects a restriction to gas flow rather than a temperature-only change. • Check which condition would most logically result from increased resistance in the gas path through the economizer. • Verify that the condition you pick is consistent with a partially plugged gas-side heat exchanger, not a water-side problem.
