  • What is coal gasification? | HowStuffWorks

    Coal gasification is said to have greater efficiency than conventional coalburning 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 turbinegenerator.
