70% to pass

Which of the listed components would be considered the dividing line separating the condensate system from the feed water system?

AMain condenser
BMain air ejectors
CDeaerating feed tank
DBoiler drum
AI Explanation

The correct answer is C) Deaerating feed tank. The deaerating feed tank is the dividing line between the condensate system and the feed water system. The condensate system collects and returns the condensed steam to the deaerating feed tank, while the feed water system takes the water from the deaerating feed tank and supplies it to the boiler. The deaerating feed tank removes dissolved gases from the condensate, preparing the water for use in the boiler. The other options are incorrect because they are not the dividing line between the two systems. The main condenser is part of the condensate system, the main air ejectors are used to remove air from the condensate system, and the boiler drum is part of the feed water system.
