  • What is coal gasification? | HowStuffWorks

    Coal gasification is said to have greater efficiency than conventional coal-burning because it can effectively use the gases twice: the coal gases are first cleansed of impurities and fired in a turbine to generate electricity. Then, the exhaust heat from the gas turbine can be captured and used to generate steam for a steam turbine-generator.

    Coal gasification accounts for 5% of China's total coal consumption; it is a core technology in efficient and clean coal conversion, and important in the development of coal-based bulk chemicals (chemical fertilizers, methanol, olefins, aromatics, ethylene glycol, etc.), coal-based clean fuel synthesis (oil, natural gas), advanced integrated ...

  • What to Know About Coal Stoves | Hitzer

    Anthracite Coal starts differently compared to other fuel sources. There are three important factors that must occur to start Anthracite Coal successfully. The three factors are air flow, heat source, and fuel. First, there must be air flow and the air must come from the bottom and flow up through the coal.

  • What was the importance of coal during the Industrial ...

    The Industrial Revolution could not have happened without coal. The early iron industry had used wood as a fuel source, but in the process had virtually stripped the North of England of its forests. The development of coal fired steam engines allowed the concentration of industry in the cities and eliminated the dependance on water and wind power.
