If the cooling water flow through the air...

🔍 Key Concepts

• Condensers and air ejectors in a steam plant: what they do with steam and non‑condensable gases • Effect of insufficient cooling water on condensation and vacuum (pressure) in condensers • Relationship between condensing efficiency and downstream components like DC (de-aerating) heater and air ejectors

💭 Think About

• Think about what happens inside a condenser if the cooling water is too warm or insufficient—does more or less steam condense? How does that affect pressure? • Which listed component is most directly impacted by poor condensation of steam and removal of non-condensable gases in the condenser system? • Ask yourself: does inadequate cooling water make levels rise because of more condensation, or does it make condensation worse and change the pressure conditions?

✅ Before You Answer

• Verify which part of the system actually establishes and maintains the vacuum/absolute pressure in the main condenser. • Check which options involve material damage or flooding, and decide whether those are direct, immediate results of low cooling water flow in the intercondensers/aftercondensers. • Confirm whether the DC heater level is controlled primarily by feedwater/condensate balance, or by the cooling water rate through air ejector condensers.

If the cooling water flow through the air ejector intercondensers and aftercondensers is inadequate, which of the problems listed will occur?

Air ejector nozzles will erode.

Aftercondenser will be flooded.

DC heater level will rise

Main condenser absolute pressure will increase.
