Death spiral goes global – 42% of global operating fleet unprofitable in 2018 and 72% by 2040 independent of additional climate or air pollution policy. Where profitability is defined as revenues minus long-run operating costs, our analysis finds that due to high fuel costs 42% of coal capacity operating today could be losing money.

The "cost of saving money" here is substantial. A similar issue exists with the larger diameter cyclones used for desliming applications. These cyclones are used to make the split between spirals and flotation. The large diameter cyclones, up to 1 m diameter, produce a much coarser separation than the smaller, 450-mm cyclones.

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. This effect has led ...
