Which of the devices listed is used to keep overheated condensate from flowing to the deaerating feed tank?
AI Explanation
The correct answer is C) 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 recirculating line allows the hot condensate to be redirected back to the main condenser, where it can be cooled before entering the deaerating feed tank. This prevents the deaerating feed tank from being overwhelmed with hot condensate, which could disrupt the proper operation of the system.
The other options, such as a recirculating line to the main feed pump (A) or the use of a freshwater (B) or saltwater (D) cooler, are not specifically designed to address the issue of overheated condensate flowing to the deaerating feed tank.
