Q

Fins are installed on the generating tube surfaces in waste heat boilers to __________.

🔍 Key Concepts

• Heat transfer in boilers (conduction, convection, and how surface area affects heat exchange) • Purpose of fins on tubes or radiators in general engineering applications • Effect of fins on gas flow vs. surface area inside heat exchangers

💭 Think About

• Think about what adding fins does to the total surface area of the tube that is in contact with hot exhaust gases. • Consider whether fins are usually used to speed the flow of a fluid, protect against erosion, or to improve heat exchange. • Recall other equipment that uses fins (like car radiators or air-cooled engines) and what the fins are meant to accomplish there.

✅ Before You Answer

• Verify which choice directly relates to increasing heat transfer surface area rather than changing gas speed or preventing damage. • Check whether fins would realistically block or reduce soot buildup and erosion, or simply expose more metal to the hot gases. • Confirm that in most heat exchangers, the main design goal of fins is improved thermal efficiency, not protection from fire or erosion.
