Abstract：Preparation of CWS with industrial waste water is a clean coal technology beneficial to environment protection. The combustibility of CWS with industrial waste water from the coking plant was studied. The TG-DTA-DTG thermal analysis technology was applied to study the combustibility of coal industrial waste water slurry, the effect of coal quality on the combustibility of coal water slurry, and the difference in combustibility between fine coal and CWS . The result shows that the ignition temperature of CWS is lower than that of fine coal. The temperature at which burning velocity reaches the highest is a little higher than that of fine coal. The ratio of volatile to the heat value of fixed carbon in coal water slurry is the same as or a little higher than that in fine coal. The result also indicates that to produce coal water slurry using industrial waste water is feasible.
