Which of the conditions listed could cause a boiler economizer to leak?

Question 1 of 27070

Which of the conditions listed could cause a boiler economizer to leak?

🔍 Key Concepts

• Function and location of a boiler economizer in the exhaust gas path • What water hammer is and how it affects piping, tubes, and fittings • Typical failure modes of heat-exchanger tubes (thermal stress vs. mechanical shock)

💭 Think About

• Ask yourself which option would create sudden, high mechanical stress on economizer tubes or headers rather than just changing temperatures or pressures gradually. • Consider which condition is most likely to cause cracking or joint failure in metal tubes carrying water. • Think about real-world engine room casualties you’ve read about: which of these conditions is frequently associated with ruptured piping or tube leaks?

✅ Before You Answer

• Verify which condition can create shock loads or pressure surges inside the water side of the economizer. • Check whether normal operating changes in temperature or pressure (high/low) usually cause immediate leaks, or just long‑term wear. • Confirm how an economizer is connected in the feedwater system and what kind of dynamic forces it might see during abnormal operations.
