Question 51General Subjects - 1st Asst/Chief
70% to passExcess brine accumulated in the distiller, shown in the illustration, is removed during normal operation by _______________. Illustration MO-0111
Aorifice "19" regulating the amount of feed water entering the distiller, thereby preventing excess brine accumulation
Bopening the drain valve located to the left of orifice "19"
Cthe hydrokineter labeled "21"
Dthe continuous action of ejector "22"
AI Explanation
The correct answer is D) the continuous action of ejector "22". The illustration shows a distiller system, and in a distiller, excess brine is continuously removed by the action of the ejector labeled "22". The ejector uses the suction created by the flow of steam or air to draw out the excess brine, preventing it from accumulating in the distiller. This is a normal part of the distiller's operation and is the primary means of removing excess brine. The other options are incorrect because: A) the orifice "19" regulates the feed water, not the brine removal; B) there is no drain valve shown to the left of orifice "19"; and C) the hydrokineter "21" is not involved in the brine removal process.
