🔍 Key Concepts

• Role of the main condenser in a steam plant during startup • Purpose of recirculating condensate instead of sending it to the feed system immediately • How air ejectors and vacuum are established and what they need to operate correctly

💭 Think About

• Ask yourself: when the turbine is only being warmed and not yet on full load, where should the condensate reasonably be going, and why might it NOT be sent forward to the rest of the feed system yet? • Consider what part of the plant actually needs a steady flow of relatively cool condensate during vacuum raising: the condenser shell, the air ejector condensing section, or some other component? • Think about which of the listed choices is a startup-specific concern versus a normal operating-level control (like maintaining levels).

✅ Before You Answer

• Be clear on the primary function of the main condenser: what does it do for exhaust steam and how does that help maintain vacuum? • Verify which components (air ejector, condenser shell, DC heater) are directly affected by the condensate flow path during initial vacuum raising. • Check which option describes a condition that is critical specifically during vacuum raising and turbine warm‑up, not just during routine steady operation.
