Question 135Steam Plants - Assistant Engineer

The correct answer is A) Condensate. Condensate is typically used as the cooling medium for the gland exhaust condenser, inter condenser, and after condenser of an air ejector unit. This is because condensate is already heated water from the steam system, making it an efficient and readily available cooling source for these components. Using condensate avoids the need to draw in additional cooling water, such as sea water or potable water, which would require more equipment and energy to circulate. The other options are incorrect because sea water (B) would require additional equipment and piping, potable water (C) is not a typical cooling medium for these components, and evaporator distillate (D) is a separate freshwater source that is not normally used for this purpose.
