Question 467Steam Plants - Assistant Engineer
70% to passRecirculation of the feed water ensures a flow of water through the _______________.
Athird stage heater
Bstandby feed pump suction line
Ceconomizer
Dmain feed pump
AI Explanation
The correct answer is D) main feed pump. Recirculation of the feed water ensures a flow of water through the main feed pump. This helps to prevent the main feed pump from running dry and overheating, which could damage the pump. The recirculation line allows a portion of the feed water to be diverted back to the suction side of the main feed pump, ensuring a continuous flow of water through the pump. The other answer choices are incorrect because they do not directly relate to the recirculation of feed water through the main feed pump. The third stage heater, standby feed pump suction line, and economizer are not the primary components affected by the feed water recirculation process.
