  • Coal Cleaning an overview ScienceDirect Topics

    Coal cleaning does add additional cost to the coal price; however, there are several benefits to reducing the ash content, including lower sulfur content, less ash to be disposed, lower transportation costs because more carbon and less ash is transported (since coal cleaning is usually done at the mine and not at the power plant), and increases in power plant peaking capacity, rated capacity, and availability [11].
