However, as the Industrial Revolution gained speed, demand for fuel rapidly increased. Before the Industrial Revolution, there were two different types of mines: bell pits and drift mines.

the pumping station's boiler room. Here eight Lancashire boilers burnt coal, heating up water to create steam for the operation of the engines. The adjoining room was the coal storage area. The windows which you can see along the far wall would have been openings where the coal was delivered into the building. Imagine this area full of coal.

Coal trader's web sites give base prices in the international market. We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.

In plants that burn pulverized coal, silos feed coal pulverizers (coal mills) that take the larger 2-inch (51 mm) pieces, grind them to the consistency of face powder, sort them, and mix them with primary combustion air which transports the coal to the furnace and preheats the coal to drive off excess moisture content. A 500 M We plant may
