The DC Heater functions to _______________.
AI Explanation
The correct answer is D) store, heat, and deaerate feed water.
The DC (deaerating condenser) heater functions to store, heat, and deaerate the feed water before it enters the boiler. This is an important step in the feed water system to remove non-condensable gases like oxygen and carbon dioxide, which can cause corrosion in the boiler. Deaerating the feed water helps maintain boiler efficiency and integrity.
The other answer choices are incorrect because they do not accurately describe the primary purpose of the DC heater. Options A, B, and C describe different components or functions of the feed water system, but are not the main purpose of the DC heater specifically.
