Question 1 of 27070

The loop seal connected to the main condenser returns the drains from the __________.

🔍 Key Concepts

• Main condenser and auxiliary condensers in a main propulsion steam plant • Purpose of a loop seal in a condenser drain system • Where intercondenser, aftercondenser, and vent condenser drains are normally routed

💭 Think About

• Think about what a loop seal does in terms of pressure and preventing steam or air from backing into another component. Which drains would need that kind of protection before returning to the main condenser? • Consider how the air-ejector system works: where does the steam used in the air ejectors finally end up, and how are those drains handled? • Ask yourself whether the intercondenser, aftercondenser, and vent condenser are separate, unrelated systems, or parts of one overall air-ejector/condenser drain return path.

✅ Before You Answer

• Verify which components are part of the air ejector/condenser system associated with the main condenser. • Check whether each of the listed condensers (intercondenser, aftercondenser, vent condenser) discharges its condensate/drain back to the main condenser under similar conditions. • Confirm where a loop seal would be placed to maintain vacuum and prevent air/steam from flowing backward into the main condenser.
