Modelling for Air Quality Estimation for a Planned Coal …
However, Indian coal contains a much higher amount of ash content ranging from 30 to 45% [1]. Thus, the requirement of coal with permissible ash content needs proper design of washeries. Some non-coking coals are also cleaned to get better heat per unit of coal burned in thermal power plants. The major air pollution sources in washery area is ...

Practical Difficulties Associated with the Indian Coal Washeries…
Studies have shown that the actual clean coal yield in most of the Indian coal washeries is much lower than that of the theoretical yield. Improper quantification of raw coal qualities and inappropriate maintenance of operating conditions for the processing equipments are often believed to be the two major causes for this lower yield.
