    Sulfur in coal exists in inorganic and organic forms, the former being mostly pyritic sulfur. Total sulfur contents in major coalfields are in the range of roughly 0.5–10 wt%. 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.
