Question 344Steam Plants - Assistant Engineer

The correct answer is A) atmospheric drain tank. Clean low-pressure steam drains are collected in the atmospheric drain tank. This is because the atmospheric drain tank is designed to receive and store these clean, low-pressure condensate drains from various systems on the vessel, allowing them to be reused in the steam system. The other options are incorrect because: B) the main condenser hotwell is used to collect the condensed steam from the main condenser, not low-pressure drains; C) the deaerating feed water heater is used to remove dissolved gases from the feed water, not collect drains; and D) the contaminated drain inspection tank is used for drains that may contain contaminants, not clean low-pressure steam drains.
