🔍 Key Concepts

• Direct-contact (D.C.) heater / deaerating feed heater in a marine steam plant • Difference between feedwater treatment vs. feedwater storage and heating • Role of air ejectors or vacuum pumps in removing non‑condensable gases from the condenser

💭 Think About

• Ask yourself: Where in the steam cycle is the D.C. heater located, and what two or three jobs does it usually do at that point in the cycle? • Which piece of equipment is normally responsible for removing non‑condensable gases from the main condenser itself? Is that the same as the D.C. heater? • Does a D.C. heater mainly perform chemical treatment, or is it more about heating, storing, and mechanically removing dissolved gases from the feedwater?

✅ Before You Answer

• Identify which option describes more than one function together (storage, heating, deaeration) in a single component. • Eliminate any choice that really describes the job of air ejectors or vacuum pumps on the condenser, rather than the D.C. heater. • Be careful not to confuse chemical treatment done in a treatment plant with thermal/mechanical deaeration done in the D.C. heater.
