By optimizing the drying process, the efficiency of brown coal power plants could be increased by 46% [19]. At present, burning brown coals produces more carbon dioxide (about onethird more), than burning black coals [18]. When the moisture of the coal is reduced from 60 to 40%, the relative reduction of CO 2 /MWh can reach 30% [20]. Thus ...
