Dec 12, 2016· COAL PREPARATION 3. What Is Coal Preparation? • Coal preparation is the removal of undesirable material (ash, Sulphur, moisture)from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities.
It was found that the optimum CC preparation temperature was 250 °C (CC250) for high strength coke preparation. 4. Whereas increasing the blending ratio of CC250 to cakingcoal decreased the coke strength, the extent of the decreasing strength was smaller than that of slightlycaking coal or pyrolyzed char blended with caking coal. 5.

ABSTRACTIn this study weathering was carried out for coals (source wise) in open piles at the Bhilai Steel Plant (BSP). Imported hard coals were selected for these studies. Several methods such as alkali extraction test, measurement of the freeswelling index, and the pH of the coal slurry have been applied to monitor coal weathering. These tests suggest that the pH of the coal slurry and ...
