What gcv of coal is it when it's gar is 3600 to3800?
GAR is ((100-total moisture)/ (100-inherent moisture)) x Calorific Value in ADB So all depends on the moisture. If we assumed total moist 25% and inherent 5% so the calorific value in ADB is (95%/75%) x GAR 3800 = 4800 Gross Calorific Value ADB So all depends on the moisture in the coal...
