Sep 19, 2019 Benefits of gasification: Transporting gas is a lot cheaper than transporting coal. Help address local pollution problems. Has 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.
الدردشة الآنThe coal industry has a track record of continued improvements against environmental and economic challenges, through applying current and emerging technologies. Technologies exist and are being further developed to mitigate coal's impact – particularly around the reduction of air emissions and coal's water footprint.
