  • Recent operating experience and improvement of commercial IGCC

    In IGCC, coal is gasified and the gasifiion products are purified to remove pollutants and particulates before Slag produced in the gasifier exits through a quench bath followed by lock hoppers. There is no slag crusher used at the slag lock hopper outlet. Fly ash is removed by a cyclone and a ceramic candle filter, while
