Combustion of coal in thermal power plants produces fly ash. There are different types of coal namely anthracite, bituminous, sub bituminous and lignite. Classification of coal is based on the content of volatile matter and carbon. Coal which has less volatiles and high carbon is of superior quality. High rank coals are harder, stronger with high carbon content and produc
