Q

In securing the main turbines, steam to the second stage air ejectors should be left on for a short period of time in order to __________.

🔍 Key Concepts

• Function of air ejectors in a main condenser system • Role of non-condensable gases in affecting condenser vacuum and turbine operation • What happens inside the condenser and turbine when securing (shutting down) the plant

💭 Think About

• Think about what the air ejectors normally remove from the condenser during normal operation and why this is important for vacuum. • When you start to secure the main turbines, what changes in steam flow and temperature might cause an increase in something that the air ejectors handle? • Which option is directly related to maintaining proper condenser conditions, rather than turbine metal or bearing temperature?

✅ Before You Answer

• Verify what second stage air ejectors discharge and where they take suction from. • Ask yourself which choice deals with non-condensable gases in the condenser rather than with mechanical components like bearings or turbine casings. • Confirm which effect would be most critical to overall plant performance if not handled during shutdown.
