Which system should be tested and used when required to raise the water level in an idle boiler?
AI Explanation
The correct answer is C) Auxiliary feed system.
The auxiliary feed system is designed to supply water to the boiler when the main feed system is not in operation or when additional water is required to raise the water level in an idle boiler. This system typically includes a separate pump, piping, and controls that allow the boiler to be filled and the water level to be maintained as needed.
The other options are incorrect because: A) The superheated steam system is used to increase the temperature of the steam, not the water level; B) The desuperheated steam system is used to reduce the temperature of the steam, not the water level; and D) The chemical feed system is used to introduce chemicals into the boiler water, not to raise the water level.
