Question 392Steam Plants - Assistant Engineer
70% to passA boiler with a water capacity of 10 tons generates steam at the rate of 30 tons per hour. If the feed water quality is 0.5 ppm, the concentration of solids will increase 1.5 ppm every hour. What would be the increase in the concentration of solids within 24 hours?
A12 ppm
B24 ppm
C36 ppm
D48 ppm
AI Explanation
The correct answer is C) 36 ppm. The explanation is as follows: 1) The boiler generates steam at a rate of 30 tons per hour, and the feed water quality is 0.5 ppm. This means that the concentration of solids in the boiler increases by 1.5 ppm every hour. 2) Over a 24-hour period, the increase in the concentration of solids would be 1.5 ppm x 24 hours = 36 ppm. 3) The other options are incorrect because they do not accurately represent the increase in the concentration of solids over a 24-hour period.
