Question 46Steam Plants - 1st Asst/Chief
70% to passHigh pressure steam drains are normally discharged to the _______________.
Areserve feed tank
BDC heater
Catmospheric drain line
Ddrain and inspection tank
AI Explanation
The correct answer is B) DC heater. High pressure steam drains are normally discharged to the DC (Deaerating Condenser) heater, which is designed to remove dissolved gases from the feed water before it enters the boiler. The DC heater operates at a lower pressure than the boiler, so the high pressure steam drains can be routed to this system to be condensed and deaerated. The other answer choices are incorrect because: A) the reserve feed tank is not the normal discharge point for high pressure steam drains, C) the atmospheric drain line is for low pressure drains, and D) the drain and inspection tank is not the typical destination for high pressure steam drains.
