What is coal gasification?

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
