Adrain and inspection tank
Breserve feed tank
Catmospheric drain line
DDC heater
AI Explanation
The correct answer is D) DC heater. High pressure steam drains are normally discharged to the DC (direct contact) heater, which uses the heat from the high pressure steam to heat the boiler feedwater before it enters the boiler. This helps improve the efficiency of the steam generation process. The other answer choices are incorrect because: A) the drain and inspection tank is not the normal discharge point for high pressure steam drains, B) the reserve feed tank does not directly utilize the high pressure steam, and C) the atmospheric drain line would not be the appropriate discharge point for pressurized steam drains.
