AI Explanation
The correct answer is B) emergency feed pump.
To provide emergency feed water supply to a steaming boiler, if it becomes necessary to secure the DC heater, suction should be taken on the distilled water tank using the emergency feed pump. The emergency feed pump is specifically designed to provide a backup source of feed water to the boiler in case of a failure or disruption in the primary feed water supply.
The other options are incorrect because: A) the feed booster pump is used to increase the pressure of the feed water, not as an emergency source, C) the emergency injector discharge is not connected to the distilled water tank, and D) the main condensate pump is part of the normal feed water system, not an emergency backup.
