Desulfurization of Coal EOLSS
2017-1-16 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. Coal cleaning includes physical, chemical,
