🔍 Key Concepts

• Boiler drum construction and terminology • Difference between end closures and outer shell plates on a steam drum • Function and location of a tube sheet compared to other boiler parts

💭 Think About

• Look closely at where arrow B is pointing on the drum cross‑section – is it indicating the flat/curved end closure, the cylindrical shell, or the plate where tubes are rolled in? • Which of the listed parts is normally found at the extreme end of a drum versus along its length or at the furnace side? • In this style of water‑tube boiler, where would you expect the tube sheet that actually holds/rolls the generating tubes to be located?

✅ Before You Answer

• Verify which component forms the circular end closure of the drum in the enlarged view. • Confirm whether the surface at B has tubes rolled into it (would indicate a tube sheet) or is simply closing off the drum interior. • Eliminate any term that usually refers to the outer shell plating/furnace wrapper, which is not what the arrow is indicating.
