Which statement listed represents a vital function of the main condenser?

ACondensing of the exhaust steam from the main feed turbine pumps.
BCooling of the exhaust steam from the auxiliary exhaust system before it enters the deaerating feed tank.
CThe recovery of feed water for reuse.
DStorage of feed water for immediate use in the boilers.
AI Explanation

The correct answer is C) The recovery of feed water for reuse. The main condenser plays a vital role in the steam power plant by condensing the exhaust steam from the main turbine, allowing the resulting condensate to be reused as boiler feed water. This recovery of feed water is a crucial function of the main condenser, as it conserves water and improves the overall efficiency of the steam power system. The other options are incorrect because they do not represent the main function of the main condenser. Option A is related to the feed turbine pumps, option B is about the auxiliary exhaust system, and option D is about the storage of feed water, which is not the primary purpose of the main condenser.
