Abstract：Effect of pH value on the static stability of coal water slurry at the same conditions such as coal quality, coal size distribution, CWS concentration and additive is introduced. The static stability of CWS can be improved when increasing the pH value in system at a suitable condition. The experiment results are same when the CWS preparation by using clean coal of Huainan Wangfenggang coal preparation plant, Dongpang coal and Xinglongzhuang coal. The probable cause of the pH value effect on the static stability of CWS at these condition is also discussed.
