It depends if you want to use brown coal as a fuel source, coldry as compared to using brown coal has a massive difference(carbon footprint). Two of the properties of water is it can absorb a large amount of energy as it increase in temperature (specific heat is 4.2 calories per degree per gram) and latent heat(absorbs a lot of energy as it changes from liquid to gas). Thus a large amount of energy that is created from burning the coal is absorbed by the water, if the water content can massively be reduced using waste heat it will be a lot better environmentally.
