The main parts of a coal drying plant typically include:. 1. Feed chute: This is the inlet through which the wet coal enters the rotary dryer. 2. Rotary drum: A cylindrical drum rotates slowly, allowing the coal to be heated and dried evenly. 3. Burner: It provides a heat source for drying the coal. It can be fueled by natural gas, coal gas, diesel, or other fuels.

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 ...

Wet cooling towers (WCT) are widely used to reject the unutilized heat in coal thermal power plants (TPPs). But this comes at the cost of excessive water consumption. Adoption of aircooled condensers (ACC), also known as dry cooling systems, in all proposed Indian TPPs would reduce their water consumption by 26% in 2030. However, power producers are reluctant to install ACC due to technical ...
