Question 41Steam Plants - Assistant Engineer

The correct answer is B) The recovery of feed water for reuse. The main condenser is a vital component in a steam-powered system, as it is responsible for condensing the exhaust steam from the main engines or turbines back into feed water for reuse in the boilers. This recycling of the condensed steam is an essential function, as it allows the system to efficiently utilize the energy in the steam and minimize water/chemical treatment requirements. The other options are incorrect because they do not represent the primary function of the main condenser. Option A describes the role of the auxiliary exhaust system, not the main condenser. Option C refers to the deaerating feed tank, not the main condenser. Option D describes the function of the main feed turbine pumps, not the main condenser.
