🔍 Key Concepts

• Shell-side vs tube-side flow in a closed feedwater heater – which side normally carries extraction/bleed steam, and which carries feedwater? • Where LP bleed (extraction) steam usually enters a feedwater heater relative to the desuperheating and condensing zones • Function and location of vents and drain lines on a feedwater heater shell, especially those tied into the main condenser or air ejector system

💭 Think About

• Look at where the main extraction/bleed steam inlet is drawn in the illustration and compare its size and location with the connections marked "A". Would the primary steam source normally enter through large or small connections? • Trace the dashed steam flow path inside the heater. At the point where label "A" is located, does the internal arrangement suggest admission of steam, removal of non‑condensables, or draining of condensate? • Consider which connections would logically lead back toward the main condenser or air removal system versus those that would connect forward to turbine bleed lines or drain coolers.

✅ Before You Answer

• Verify whether the nozzle at "J" or the connections at "A" look more like the main bleed steam inlet based on size and internal baffling. • Check if the connections at "A" are located at a high point on the shell, which is where vents for non‑condensable gases are usually placed, or at a low point, where condensate drains would be. • Confirm from the flow arrows whether condensate leaves the shell through a connection at the bottom (toward a drain cooler or condenser) rather than through the top connections labeled "A".
