🔍 Key Concepts

• Function of each zone in a regenerative feed heater (desuperheating, condensing, drain cooling) • How steam and condensate flow paths are shown by the dashed lines in the illustration • The difference between a heater section and a condenser/cooler section inside the same shell

💭 Think About

• Trace where the extracted steam first enters the heater and where it gives up most of its heat to the feedwater. Which labeled section does that correspond to? • Look at where the drains from the upper section go and how they pass through the lower/tube bundle areas. What is the purpose of that mid section in the overall heat balance? • Compare the location of F to the condensate inlet and outlet arrows. Is this region primarily condensing steam, cooling drains, or heating feedwater?

✅ Before You Answer

• Verify which labeled section directly surrounds the main tube bundle that carries the feedwater • Confirm which area is handling drains from higher-pressure heaters or condenser hotwell, not main exhaust steam • Make sure the label you pick for F matches its position between the upper condensing section and the lower drain cooler section in a typical multi-zone feed heater
