【 摘 要 】
Present study is focused in the investigation of flow characteristics of bottom ash water slurry at high solid concentrations. The solid suspension of bottom ash is varied within the range of 10-60% (by weight). The rheology of solid suspension is carried out by rheometer. Experimentation is also extended to investigate the effect of detergent based additive in the flow behaviour of high concentrated bottom ash water slurry (i.e. 60%). The dosage of additive is varied in range of 1-4%. It is noticed from experimentation that bottom ash water suspension shows Newtonian flow behaviour at solid concentration range up to 30%. Whereas, slurry exhibits Non-Newtonian flow characteristics above solid suspension of 40%. It is also seen that the viscosity of slurry increase with solid concentration. Addition of sodium triphosphate leads to appreciable decrease in the slurry viscosity as dosage of additive is increased. The optimum addition of additive is found as 3% (by weight).
