Question 1 of 27070

Q

Recirculation of the feedwater ensures a flow of water through the __________.

🔍 Key Concepts

• feedwater recirculation in a boiler system • purpose of an economizer and why it needs protection • what happens to heat transfer surfaces if flow stops while hot gases continue

💭 Think About

• Which part of the feedwater system is directly exposed to very hot exhaust gases and can overheat quickly if water flow stops? • Is recirculation mainly to keep a pump ready, or to protect a heat‑transfer surface from damage? • When the boiler is steaming very little or is shut in, which component still sees hot gas flow and therefore must still have water moving through it?

✅ Before You Answer

• Identify which choice is located in the gas path of a boiler and not just in the water path. • Confirm which component is most vulnerable to overheating or tube damage if water flow is lost. • Verify whether recirculation lines are normally arranged around pumps, heaters, or across the boiler gas‑side heat exchanger.
