🔍 Key Concepts

• Follow the condensate flow path shown by the arrows through sections E, F, and G in the heater • Recall what function an aftercondenser, drain cooler, and gland exhaust condenser each performs in a steam cycle • Identify which section of the heater is in direct contact with the coolest condensate and which section handles exhaust or drains

💭 Think About

• Look at where condensate enters and leaves the heater in the illustration; how does the flow direction help you decide what duty section G is performing? • Which component would logically be located above the main heating section so that cooler drains or vapors can give up their remaining heat before discharge? • Compare the typical duties of an aftercondenser, first stage heater, drain cooler, and gland exhaust condenser— which one normally shares the same shell as a low‑pressure feedwater heater?

✅ Before You Answer

• Verify which label (E, F, or G) is associated with the lowest temperature section, where drains are finally cooled before discharge • Confirm whether any gland exhaust piping is shown connecting directly to section G • Check if the outlet from section G sends liquid to condensate return/drain system rather than back into live feedwater flow
