Abstract |
During the combustion of fossil fuels, sulfur oxide compounds are formed and released to the atmosphere. Where it is feasible to physically remove pyrite from coal in significant quantities, the amount of sulfur oxide produced from coal firing can be reduced. The objective of the work was twofold; first, to extend the washability data to finer sizes of coal, and second, to evaluate coal cleaning methods and techniques for removing pyritic sulfur from the fine-sized coal. The coals evaluated were low in pyritic sulfur and little improvement could be made in sulfur reduction by gravity separation. The coals high in pyritic sulfur were also high in organic sulfur so that the total sulfur reductions obtained were not as impressive as previously reported reductions. (Author) |
