Saving Water

Coal is one of the most common fuels for generating heat and electricity.
A lot of coal fired power plants all around the world have to handle their ashes that remain after the incineration. If they cannot sell off the ashes they have to dispose them somewhere. When water consumption is no issue the easiest way is to mix the ashes with a lot of water, that means ratio 1:15 or 1:10, and dispose it in large ponds or other cavities.
 
In most of the countries world wide the reasonable usage of water is a hard fact and has to be followed, which means saving water as much as possible offers advantages to ash handling systems.
 
By reducing the water content the life time of the disposal area will be extended drastically because the pumped volume is reduced significantly.
 
Using high density solids pumps which can handle mixing ratios up to 75 % solid content will give the operator a much wider window of how to run his system accordingly to the real ash amounts that occur. The generated ash amount can vary throughout the year.
 
To always cope with those changes a system is required that can easily be adjusted to handle low and high density mixtures.
