Abstract

 Classification of coals from Katas Nasir Gali, District Chakwal, Pakistan has been carried out according to ASTM method. Besides proximate analysis, calorific values, chlorine and sulphur contents have also been determined. Calorific value of these coals ranges from 5,000 to 6,000 Btu/lb; sulphur contents are not high and chlorine contents are as high as 2,500 ppm. The Katas Nasir Gali coals can be classified as subbituminous A to high volatile C bituminous.
