In this paper, numerical models of coal-water gasification process are formulated and used to describe coal gasification within Texaco gasifier which is normally used in modern coal power plants. To identify operation performance of Texaco gasifier, Aspen plus software is employed to process the numerical simulation and a typical Chinese coal-Beisu coal-was selected to be dealed with by the gasifier. Important parameters affecting gasifier's gasification performance including coalwater slurry concentration, oxygen-Coal ratio and oxygen concentration are analyzed Numerical results show thatimprovingthe coal-water slurry concentration will significantly increase the contents of active ingredients in raw gas; hydrogen and carbon monoxide, and increasing oxygen-Coal ratio and the concentration of oxygen will decrease their contents.
