Question 168Steam Plants - Assistant Engineer

The correct answer is C) inter condenser. The loop seal connected to the main condenser returns the drains from the inter condenser. The inter condenser is a type of condenser located between the main condenser and the auxiliary condenser, used to further cool and condense steam. The loop seal ensures that the condensate from the inter condenser is properly returned to the main condenser, completing the cycle. The other options are incorrect because the after condenser and vent condenser are different types of condensers that are not directly connected to the main condenser's loop seal in this manner.
