A precommercial demonstration plant is currently being constructed at an existing power plant as a final step before the commercial implementation of a largescale power plant fired using dried coal. The extent to which these processes are suitable for lignite drying first has to be demonstrated in plants of an appropriate size.
Designing a thermal coal drying system is quite different than developing drying systems for most other materials. Considering the wide range of coal types and processing applications, system requirements and drying characteristics vary greatly.

May 15, 2016· Not many commercially proven coal drying plants are in operation worldwide at coal plants. Most of these problems can be addressed if the focus is shifted from coal drying at the plant site to coal drying at the mine, particularly in the context of imported Indonesian coal for Indian power plants, and other similar applications.
Coal preparation is the removal of undesirable material from the runofmine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of coal and the impurities. Through proper coal preparation, a uniform product is achieved. Typical steps in coal preparation include: Crushing
