| Abstract: | The feasibility of preparation of high concentration slurry coal water mixture （SCWM） which from Shanxi coal mine was studied, the coal slurry＇s ability to be a mixture with water and its influencing factors were investigated. The optimum conditions of the preparation of SCWM were obtained under single-factor tests and orthogonal tests. The optimum condition is that the additive amount is 0.16%, the temperature is 35℃, the agitation intensity is 1200r/min, the stirring time is 25min. Under the best condition, the SCWM of Grade 1 which has the properties of the concentration of 69% , the viscosity of 911.30mPa·s and the calorific value of 20.60MJ/kg has been obtained. The SCWM is up to the standards of GB/T 18855 -2002 CWM technical. |
