🔍 Key Concepts

• Trace the auxiliary exhaust line on the diagram and note every component it physically connects to • Distinguish between auxiliary exhaust steam and bleed steam (taken from turbine stages) in the illustration • Pay attention to the lettered circles (A, B, C, etc.) and what pressure/source is associated with each

💭 Think About

• Which line on the drawing is clearly labeled as coming from auxiliary exhaust or going to the auxiliary condenser? Follow that specific line and see what equipment it feeds before it reaches the condenser or tank. • Look at where the air ejectors, air heaters, and any bleed steam systems are connected. Are they tied into the turbine casing (bleed points) or do they discharge to/receive steam from the auxiliary exhaust header? • Compare the pressures and labels in the table with the lettered connection points on the piping. Which of the choices operates at the pressure range shown for the auxiliary exhaust connection?

✅ Before You Answer

• Verify which lettered connection(s) are explicitly identified as auxiliary exhaust or are routed to the auxiliary condenser. • Confirm whether each answer choice is supplied by bleed steam from a turbine stage or instead by exhaust steam from auxiliary equipment. • Double‑check the flow direction arrows around the air ejectors, air heaters, and bleed steam lines to be sure which way steam is moving before deciding.
