energy efficiency of coal burned boilers

  • What happens when coal is burned in a boiler? - Food News

    What is produced when coal is burned in a power plant? Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant, boilers produce steam at a high pressure and temperature.Get Price
