sufficient coal reserves available to keep the power station in operation should the mine experience production problems. Inside the power station, the coal is pulverised to a fine powder in giant grinding mills. This is because pulverised coal burns quickly, like gas. The pulverised coal is transported to the boiler furnace with air where it ...

Anthracite coal has higher carbon content and is much harder than bituminous coal, thus earning the nickname "stone coal" in its early years of use. In 1803, Philadelphians watched a load of anthracite coal actually squelch a fire during a trial run, and city officials used the load of "stone coal" as attractive gravel for sidewalks.
The new Hot Rolling Mill has an output capacity of 4.4 million tons per year of specialized steels for industries such as the automotive and white goods sectors.
