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 furnacelike device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam.
