🔍 Key Concepts

• Difference between natural circulation and accelerated natural circulation in boilers • Role of density difference between downcomer water and steam-water mixture in riser tubes • Physical design features that increase circulation rate without using pumps

💭 Think About

• Ask which choice preserves the idea of natural circulation (no mechanical pump) yet makes circulation faster • Consider how gravity and density differences cause water to move through downcomers and risers—what design change would make that effect stronger? • Think about which option directly affects the driving head between downcomers and generating tubes, rather than just improving heat recovery elsewhere

✅ Before You Answer

• Verify which option still relies on natural circulation (no forced pump) • Check which change would increase the vertical component of the height difference between hot and cold legs of the circuit • Eliminate answers that mainly affect heat recovery in other components (like economizers) rather than the boiler circulation loop itself
