🔍 Key Concepts

• Clean vs. contaminated drains in a steam system • Purpose of an atmospheric drain tank versus other tanks • How low-pressure steam is usually condensed and returned in marine boilers

💭 Think About

• Ask yourself: which choice is specifically designed to receive clean condensate from low‑pressure steam, not dirty or oily drains? • Which tank normally operates at or near atmospheric pressure and is a collection point for drains before they go back to the feed system? • Which of these options is more of a processing/working component (like heating or deaerating) rather than just a collection point for drains?

✅ Before You Answer

• Verify which equipment is labeled for clean vs. contaminated drains in standard engine‑room piping diagrams. • Check which tank is normally vented to atmosphere and used to collect low‑pressure steam drains. • Confirm that the option you choose is not primarily for fuel/air removal or main condensate collection, but for drain collection.
