Which of the devices listed is used to keep overheated condensate from flowing to the deaerating feed tank?
AI Explanation
The correct answer is B) Recirculating line to the main condenser.
The recirculating line to the main condenser is used to keep overheated condensate from flowing to the deaerating feed tank. This allows the condensate to be cooled down before entering the deaerating feed tank, preventing damage to the tank and other equipment from excessively hot condensate.
The other options are incorrect because: A) A fresh water cooler is used to cool the main engine jacket water, not the condensate. C) A salt water cooler is used for cooling the main condenser, not the condensate. D) A recirculating line to the main feed pump would not serve the purpose of cooling the overheated condensate.
