Question 72Steam Plants - QMED
70% to passClean low pressure steam drains are collected in the _______________.
Adeaerating feed water heater
Bcontaminated drain inspection tank
Catmospheric drain tank
Dmain condenser hotwell
AI Explanation
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.
