Why Coal fired power station is not sensible in a dry country.

As I studied metallurgy I know about materials at high temperature. The tubes that carry water to be turned into steam are susceptable to internal and external corrosion and being blocked by deposits that will inhibit flow causing hot spots. Any of the above problems can cause drastic failure, loss of life, and shutdown. To avoid internal corrosion and blockages the water has to be very pure, that is high quality drinking water, that  gets turned into steam and often vented away.
In a country that has a rainfall far less than the world average and is considering desalination (that is more coal fired energy consumption), it would make more sense to just stop using coal and change to renewable energy to reduce water and CO2 production.
We need sensible sustainable technologies.
