Coal Beneficiation Technology Ranchi, August 2007 20 UTILISATION OF COAL WASHERY REJECTS: #190;The reject from the washery would be burned in fluidized bed based boiler to raise steam for Power generation. #190;The ash would be between 5060% and a GCV of 1300 2400 Kcal/kg. #190;Fluidized Bed Boiler Types would be used for these generating stations.
The washability characteristics of a coal reserve are provided by obtaining liberation data on the raw coal sample. Liberation refers to the amount of physical breakage required to liberate coal from different other material densities. Low density material is clean coal whereas high density material is reject (rock).
Coal Beneficiation Technology Ranchi, August 2007 3 Introduction: The Coal Washery Rejects are the major environmental hazard during the process of Coal Washing. Considering the fact of requirement of millions of tones clean coal for the endusers, mainly power houses, this problem will have to be solved effectively.
Coal: The blend of coal and coal washery rejects in the ratio of 22:78 will have GCV of about 2,000 Kcal/Kg and ash content of about 58%. The Coal washery rejects and coal requirement will be about 4 MMTPA (corresponding to 75% PLF). Project developer has applied to RVUNL
The coal washery rejects levy applies to each tonne of coal washery rejects that is received from offsite and applied to land. Coal washery rejects are wastes resulting from washing coal, including substances such as coal fines, soil, sand, and rock. The coal washery rejects levy is adjusted annually according to the Consumer Price Index (CPI).
