Question 35Steam Plants - QMED

The correct answer is D) after condenser. The air accumulated in the intercondenser of the air ejector assembly is discharged directly to the after condenser, which is the proper location for this discharge. The air ejector system is designed to remove non-condensable gases, such as air, from the main condenser to maintain vacuum and improve the efficiency of the steam turbine cycle. The air ejector discharges this accumulated air into the after condenser, where it can be safely vented to the atmosphere. The other options are incorrect because: A) the high-pressure turbine is not the proper location for discharging air from the air ejector; B) the main condenser is not the correct destination for this air discharge; and C) discharging directly to the atmosphere would not be the appropriate or safe method for disposing of the accumulated air.
