Thixotropy of highly loaded coal-water slurries

Abstract

For the better preparation of highly loaded coal-water slurries in coal utilization processes, the thixotropic behavior of CWM was simulated by means of a new thixotropy model employing the yield stress as a structural parameter. Ways to imrpove the slurry preparation method were studied by combining the experimental results of thixotropy and stability measurements. It is concluded that the thixotropic parameter determined in this work is useful in judging the stability of CWM. © 1984, The Society of Chemical Engineers, Japan. All rights reserved.
