Question 99Steam Plants - Assistant Engineer

The correct answer is C) emergency feed pump. In the event that the DC heater needs to be secured, the emergency feed pump should be used to take suction from the distilled water tank to provide emergency feed water supply to the steaming boiler. The emergency feed pump is specifically designed for this purpose, as it can draw water from an alternate source, such as the distilled water tank, to maintain boiler water levels in an emergency situation. The other options are incorrect because: A) the emergency injector discharge is not used to supply feed water; B) the feed booster pump is not intended for emergency situations; and D) the main condensate pump is not the appropriate equipment for this emergency scenario.
