Question 72Steam Plants - QMED

The correct answer is C) atmospheric drain tank. The atmospheric drain tank is the designated collection point for clean low-pressure steam drains on a vessel. This is because the atmospheric drain tank allows the condensed steam to vent to the atmosphere, preventing any backpressure on the low-pressure steam system. The other options are incorrect because: A) the deaerating feed water heater is used to remove dissolved gases from the feed water, not collect steam drains; B) the contaminated drain inspection tank is for collecting oily or contaminated drains; and D) the main condenser hotwell is where the main steam condenses, not where low-pressure steam drains are collected.
