Coal found in sedimentary rock, is crushed into the appropriate size and used as fuel for electricity generation or the iron-making process.Lumps of coal can be used directly as a fuel.However some coal is first washed to make it into high grade coal.It can also be sorted into various sizes, depending on what the fuel is required for.

2011-9-1 The chemistry of stone coal is characterized by high content of ash and sulfur and low carbon content and heat value. The content of ash and sulfur in most stone coal is within the range of 70%–90% and 2%–5%, respectively, while some stone coal has the low ash content, 20%–40% but high sulfur content up to 13.5% (Jiang et al., 1994). The carbon content mostly ranges from 10% to 20% and the

1994-8-1 The flue gases are cleaned by high-efficiency cold-side electrostatic precipitators (ESPs) and in all large coal-fired power plants they are cleaned by flue-gas desulfurization (FGD) installations of the lime(stone)/gypsum process. Following the reintroduction of coal as a fuel for power plants, the environmental consequences for electricity generation have been thoroughly studied; for instance in the Dutch National Coal
