Study on stability of coal water slurry under different coal water slurry dispersants by using stability analyzer

Abstract

The stability analysis of CWS by Turbiscan Lab stability analyzer not only can clearly observe the change of the supernatant layer in the slurry, but also can observe the change of the turbid area. It can objectively reflect the agglomeration and flocculation in the slurry, Settlement and a series of changes. The results show that the sedimentation mainly occurs in the coal-water slurry system made by HSC and HS, and the coal-water slurry system produced by NSF mainly reunion and sedimentation. The three dispersants on coal-water slurry stability enhancement ability were: HSC> HS> NSF.
