Question 67General Subjects - 1st Asst/Chief70% to pass
Irregular feeding or surging of the feed water supply to a flash evaporator may be attributed to _______________.
AI Explanation
The correct answer is B) a dirty strainer in the salt water feed pump suction line.
A dirty strainer in the salt water feed pump suction line can cause irregular feeding or surging of the feed water supply to a flash evaporator. This is because the strainer becoming clogged will restrict the flow of seawater into the feed pump, leading to fluctuations in the water supply to the evaporator.
The other options are incorrect because:
A) A clogged vent line from the air eductor condenser would not affect the feed water supply.
C) Excessive pressure in the sea water feed heater would not cause irregular feeding or surging.
D) Erratic water flow through the air eductor would not directly impact the feed water supply to the evaporator.
