COARSE DRY COAL CLEANING Energy

2013-2-21  Dry Coal Cleaning Applications in India Many coals located <1000 km away from the utility are not cleaned. As a result, 40%-45% ash coals are transported and used in utilities designed for 25%-35% ash coal. For a relatively easy-to-clean India coal, dry cleaning has the ability to reduce the ash from 41% to 30%. 0 5 10 15 20 25 30 <1.35 1.35-1
