Recirculation of the feed water ensures a flow of water through the _______________.

Astandby feed pump suction line
Bthird stage heater
Cmain feed pump
Deconomizer
AI Explanation

The correct answer is C) main feed pump. Recirculation of the feed water ensures a flow of water through the main feed pump. This is important to prevent the main feed pump from running dry and potentially becoming damaged. The recirculation line allows a portion of the feed water to be redirected back to the suction side of the main feed pump, ensuring a continuous flow of water through the pump and maintaining proper lubrication and cooling. The other answer choices are incorrect because they do not involve the main feed pump. The standby feed pump, third stage heater, and economizer are not directly related to the recirculation of feed water through the main feed pump.
