Workshop on Clean Coal Technology Power Plants are designed for a particular Coal Quality range and deviation in quality adversely affects the performance and efficiency of the Plant. The key area of concern are: Ash in coal - As high as 45%. Inconsistency in Quality of Coal. Chemical Quality Physical Quality. These issues can by and large be addressed by resorting to Coal beneficiation.

Coal Rejects are basically a by-product of the coal washing or coal beneficiation process in which after separation of beneficiated washed coal and Middlings, the rejects are left over as a portion of raw feed coal. These are generated from the coarse circuit of the coal washery process.
