Question 94Steam Plants - 1st Asst/Chief

The correct answer is D) The recovery of feed water for reuse. The main condenser is a vital component in the steam power plant of a vessel, as it plays a crucial role in the recovery and reuse of feed water. The main function of the main condenser is to convert the exhaust steam from the main turbine back into water (condensate) through the process of condensation. This condensate is then returned to the feed system, where it can be reused as feed water for the boilers, completing the steam cycle and improving the overall efficiency of the system. The other options are incorrect because they do not accurately represent the main function of the main condenser. Option A is incorrect as the main condenser is not used for the storage of feed water. Option B is incorrect as the main condenser is not involved in the cooling of the auxiliary exhaust system. Option C is incorrect as the main condenser is not responsible for condensing the exhaust steam from the main feed turbine pumps.
