In China, promotion of a Clean Coal Technology (CCT) business becomes urgent to deal with stringency of the energy supply such as electricity or liquid fuel and intensification of an environment problem with raped economic development. The spread of CCT based on coal gasification is carried out flourishingly because of it's high efficiency and Low atmospheric pollutants emission. China has abundant coal resources with high ash fusion temperature (flow temperature>1400℃) and the high ash fusion temperature coal is account for about 55% of annual output and 57% of retain coal reserves. Then it will meet some slagging problems when using slagging gasifiers which exist in IGCC with high ash fusion temperature coal. Therefore a new coal gasification process to fit Chinese high ash fusion temperature coal was discussed in this paper.
