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.

In 1855, the first drying of brown coal started at the von der Heydt mine in Ammendorf in central Germany, where a "clean coal" was produced through drying and pressing without a binder. The first registration of a patent for a pipe dryer for use in drying brown coal was made three decades later in 1884. The drivers behind coal drying

Depending on the coal drying method and the method of recovering heat from the vapours in the power plant system, an up to 5% increase in power unit efficiency can be achieved [61, 67, 78]. An additional effect of the higher power unit efficiency is a reduction in CO 2 emissions.

To achieve deeper moisture removal, the fluidized bed dryers would have to operate at higher drying temperatures at Coal Creek plant [9]. RWE has WTA coaldrying technology that is capable of removing a high percentage of moisture from lowgrade coal. The WTA process can dry the feed to moisture contents as low as about 12%.

Introduction Lowrank coal (LRC) is a widely used energy source for power plants, contributing about 45% of the total global coal reserves [1]. However, the most apparent difference between the LRC and bituminous coal or anthracite coal is its high moisture content, which causes many problems in the utilization processes [2].

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 ...
