🔍 Key Concepts

• Main condenser vacuum: how it is created and maintained on a steam turbine plant • Role of the main air ejector, circulating pump, and condensate pump in condenser operation • Sequence for safely breaking vacuum to avoid damage to the condenser or turbine

💭 Think About

• Which component is directly responsible for REMOVING non‑condensable gases and thus maintaining vacuum in the condenser? • If you suddenly stop seawater circulation or condensate flow while vacuum still exists, what could happen to metal temperatures and condenser/turbine components? • When you want to intentionally lose vacuum, is it safer to first cut off the device that MAINTAINS vacuum, or to disturb cooling water or condensate flow?

✅ Before You Answer

• Identify which choice directly affects the device that maintains vacuum rather than cooling water or condensate flow • Consider which action, if taken first, minimizes risk of thermal stress or condenser damage • Verify in your steam plant notes/procedures which system is used specifically for air removal and vacuum maintenance
