  • Moving the Coal Through a Coal-Fired Power Plant

    Several years ago, a University of Illinois professor reported that to produce 109 kWh/year of power, a plant burns 14,000 tons of coal every day. He noted that the coal that goes to a typical coal-fired power plant is crushed to approximately 5 cm in size before it is loaded into the inlet hopper.

    So there's another important input of the coal power plant. They bring in coal, obviously you have to have water that you turn into steam. That's a closed loop. The other thing you bring in is gravel, calcium carbonate, limestone. You take crushed limestone and it's sitting in the bottom of this tank. And that gas bubbles through it. It's a slurry.

    4/20/2018· From the Coal Storage Plant, coal is delivered to the coal handling plant where it is pulverised (i.e., crushed into small pieces) in order to increase its surface exposure, thus promoting rapid combustion without using large quantity of excess air. The pulverised coal is fed to the boiler by belt conveyors.

    Because coal is only mined in a few regions of the country, it typically needs to be transported before being burned in a power plant. Wyoming’s Powder River Basin coal, for example, is shipped by rail to power plants as far away as Georgia. Trains move roughly 70 percent of the coal that’s transported in the United States every year

    Once unloaded, the coal is then pulverized into a fine powder by a large grinder. This ensures nearly complete burning of the coal in order to maximize the heat given off and to minimize pollutants. The pulverized coal is then input to a boiler, where combustion occurs and the coal provides heat to the power plant.

    Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or "races." The raw coal is then fed into the pulverizer along with air heated to about 650 °F (340 °C) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows out the usable fine coal powder to be used as fuel.
