🔍 Key Concepts

• main condenser operation in a steam propulsion plant • how steam condensing affects pressure and vacuum • the role of pumps and air ejectors in maintaining vs. creating vacuum

💭 Think About

• Think about what physically happens to pressure inside a closed space when large volumes of steam turn back into water. • Which device or process actually creates the low pressure (vacuum), and which ones mainly help to maintain or improve that vacuum? • Ask yourself: if this one process stopped but everything else kept running, would you still get any vacuum at all?

✅ Before You Answer

• Be clear on the difference between creating vacuum and removing non‑condensable gases. • Consider whether a pump can pull much vacuum on a space that is mostly filled with steam, or whether something has to happen to the steam first. • Verify which component would still allow some vacuum to form even if its associated equipment failed or was secured.
