Question

Select the disadvantage of cooling pond out of the given?

(a) The area required of cooling in a cooling pond is small

(b) Spray losses due to evaporation and windage run high

(c) There is no control over the temperature of cooled water

(d) The cooling efficiency is low compared with cooling water

This question was posed to me during an online exam.

Asked question is from Cooling Ponds and Towers topic in section Steam Generators & Accessories of Energy Engineering

Answer 1

Correct choice is (c) There is no control over the temperature of cooled water

To explain I would say: The cooling effect is reduced with the decrease in wind velocity and if the load on the plant increases, the pond does not respond to the requirement. When the maximum cooling is required during increased load, it provides minimum cooling in absence of wind flow.
