🔍 Key Concepts

• Steam turbine gland sealing system – purpose of gland seals and what leaks from them • Difference between gland exhaust steam and leakoff from throttle valve glands • What a condenser generally does in a steam plant (condenses vapor to recover water)

💭 Think About

• First, identify exactly what is leaking at the turbine glands and where that mixture goes after leaving the glands. • Think about why you would want to condense the gland exhaust before sending it anywhere else in the system. • Ask yourself which option best describes dealing with condensate formed from the steam at the gland exhaust, rather than simply routing vapor somewhere.

✅ Before You Answer

• Verify which choice specifically mentions condensate at the gland seal exhaust, not at the throttle valves or elsewhere. • Check which function is most consistent with a condenser’s primary job (condensing and recovering water), rather than just directing flow or preheating. • Make sure you distinguish between gland exhaust line duties and functions related to DC heater or air ejector suction.
