A Comparative Study on Lignite Coal Drying by Different Methods

2. Materials and Methods Lignite drying technologies Drying of lignite could be classified to evaporative drying and mechanicalthermal dewatering. In this paper, we focus on the evaporative drying technologies. The evaporative drying is an energy intensive process, because water in lignite needs to absorb a lot of heat to evaporate.
