【 摘 要 】

Coal is the primary source of energy in almost every nation. As the energy demand is increasing, a greater amount of ash is generated as a result of increased coal consumption. The present study is aimed to investigate the physical, chemical and rheological properties of fly ash and its suspension with water for the design of a slurry transport system. The mineralogical composition of the fly ash shows large fraction silica and alumina. The rheological analysis shows that at lower concentrations (10-30%), the slurry behaves like a Newtonian fluid whereas it behaves like a non-newtonian fluid at higher concentrations (40-60%). The rheological characteristics can further used for the prediction of flow characteristics of the slurry in a horizontal pipe.
