Abstract

A parabolic relationship has been established between the percentage of sinks for every one per cent reduction in ash for different levels of cleans and the respective ash per cent in cleans of Shampur-Chatabar coals (size ½ in – 36 B.S.) and it is expressed by an equation Y = 4.075 + X (0.368 – 0.019 X), where Y is the weight percentage of sinks for every one per cent reduction in ash of cleans and X is the ash per cent in clean coal. Further, from the calculated value of Y, weight per cent W of clean coal can be calculated by the equation W = 100 – RY, where R denotes total reduction of ash.
