fly ash utilization in indian coal mines

CHARACTERIZATION AND UTILIZATION OF FLY ASH

2012-7-6  Indian coal is of mostly sub bituminous rank followed by bituminous and lignite (brown coal). The ash content in Indian coal ranges from 35 % to 50 %. The coal properties including calorific values differ depending upon the colliery. The calorific value of the Indian coal (~ 15 MJ/Kg) is less than the normal range of 21 MJ/kg to 33 MJ/kg (gross).
