The first and second stage air ejectors used with main steam condensers are designed to __________. establish vacuum increase condensate temperature

🔍 Key Concepts

• Role of air ejectors in a main steam condenser system • Effect of non-condensable gases (like air) on condenser vacuum and turbine efficiency • Normal causes of condensate temperature changes in a condenser (where does the heat come from?)

💭 Think About

• Think about what happens to the pressure in the condenser if air and other non‑condensable gases are removed efficiently. Does this help create or destroy vacuum? • Consider what mainly determines the temperature of the condensate: is it more affected by air removal equipment, or by the heat transfer between exhaust steam and cooling water? • Ask yourself: if an air ejector were to significantly increase condensate temperature, what effect would that have on vacuum and overall plant efficiency?

✅ Before You Answer

• Verify the primary purpose of first and second stage air ejectors in a steam condenser (what are they actually installed to do?). • Check whether any standard description of air ejectors lists heating condensate as a design purpose or just a side effect, if at all. • Confirm how condenser vacuum is created and maintained: by air removal, by condensate heating, or by steam condensation itself.
