Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands—called coal

Coal fired power plant - Energy Education

Burning huge amounts of coal. Coal plants require enormous amounts of coal. Shockingly: a 1000 MWe coal plant uses 9000 tonnes of coal per day, equivalent to an entire train load (90 cars with 100 tonnes in each!). The amount of coal used during a full year would then require 365 trains, and if each is 3 km long then a single train carrying all of this coal would need to be about 1100 km long ...

Coal – Types, Uses and Formation

Coal is formed due to the effects of heat and pressure on the remains of dead plant matter which get buried inside the Earth’s surface. After millions of years of being under high pressure and high temperature, they get transformed into fossil fuels. So, if you wonder what is the origin of coal, it is dead plant-based matter.
