In this paper, the full range of coal gasification process on the classification, development, structure and characteristics were discussed. The proper gasification process for IGCC power plant was provided. In general, the coal gasification technology of fluid injected bed is most appropriate for IGCC power plant. The gasification technology of the fluid injected bed is divided into dry pulverized coal and wet coal-water slurry feed in two ways. IGCC net power or with heating units, the suitable gasification technology is the dry pulverized coal gasifier with higher power generation efficiency, long life equipment and combustion nozzle, low operating costs. IGCC and coal-based joint product, the proposed project is coal-water slurry using wet cooling program. When producing chemicals, wet cooling program do not need to fill a large number of steam into the transformation of CO for methanol synthesis and hydrogen production, and wet coal-water slurry feed gasifier is domestic, so with low-cost initial investment. Choosing of the proposed coal gasifier will be instructive for IGCC power plant construction. Key words：integrated gasification combined cy
