The effect of water on gasification reactivity is studied experimentally for the case of gasification of coal-water mixture (CWM). In this study, CWM, dry coal and dry coal with water vapor, the total amount of which is as same as that contained in the CWM are used. In all experiments, the chemical species produced, the residual volatile matter (VM), fixed carbon (FC), C, H and N molar numbers in both VM and FC, the distribution of particle diameter, the specific surface area and the structure of coal surface are analyzed along the axis of furnace. As a result, the gasification reactivity of CWM is the highest among the three fuels, since water vapor directly reacts with the dense chemical species around a particle. This phenomenon plays a part for the increase of specific surface area and the improvement of gasification efficiency.
