Types of Coal There are various types of coal, from anthracite with its high carbon content to bituminous coal, subbituminous coal and lignite (brown coal), which is an even younger coal. Power generating equipment needs to be optimized for these different types of coal.
A large thermoelectric plant like this burns a lot of coal—in this case, about 11 million tons per year. Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam.
