Question 1 of 27070

A check valve is located between the economizer and the steam drum to __________.

🔍 Key Concepts

• Economizer location and purpose in a boiler feedwater system • Function of a check valve (non-return valve) in fluid systems • What happens to flow direction if there is a tube failure or pressure change in the economizer

💭 Think About

• Think about which direction water normally flows between the feed pump, economizer, and steam drum, and what could cause that direction to reverse. • Consider what specific problem a check valve (one-way valve) is designed to prevent in this section of the system. • Ask yourself: in an economizer casualty, what might try to flow back toward the economizer, and why would that be dangerous?

✅ Before You Answer

• Verify which components (feed pump, economizer, steam drum) are upstream vs. downstream in normal operation. • Identify which choice describes a one-way protection function rather than just encouraging or assuring flow. • Check which option specifically addresses an abnormal or casualty condition involving the economizer and potential flow reversal.
