🔍 Key Concepts

• Atmospheric drain tank (ADT) function in a steam plant • Normal flow path of condensate and drains back into the system • Relationship between condensers, feed systems, and storage tanks

💭 Think About

• Ask yourself: what is collected in the atmospheric drain tank, and where in the system does that fluid logically need to return? • Which option represents the usual point where miscellaneous drains and condensate are gathered before being sent back to the feed system? • Is the ADT more closely associated with heat rejection (condenser side) or long‑term water storage (tanks and reserve feed)?

✅ Before You Answer

• Verify which piece of equipment normally collects low‑pressure drains/condensate from various parts of the steam cycle • Check standard steam plant diagrams to see where the ADT discharge line is typically led • Confirm whether the ADT is intended to feed directly into storage tanks or into a condenser as part of the main condensate recovery path
