  THERMAL POWER PLANTS

  2. Process description of a coal fired power plant A coal fired power plant burns coal to produce electricity. In a typical coal fired plant there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.

  How Coal Works

  Dec 15 2017  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
