    Desulfurization Of Coal Encyclopedia Of Life Support Systems

    In coal combustion, to generate electric power and process heat, the sulfur is emitted as SO2, which is seen as one of the main causes of acid rain. This effect has led to an interest in the three main methods of removing coal sulfur: coal cleaning, in-bed desulfurization, and flue gas desulfurization.

    Bituminous coal is easily repelled from anthracite coal under the influence of a positive charge, while it is depressed under the influence of a negative charge. Many materials are either repelled more easily or depressed by application of the best polarity. Fig. 2, Typical Electrostatic Separator Diagram
