Role of specific gravity of fly ash in evolving slurry density set point for high concentrated slurry disposal system


Author(s): Deepthi G V, Shashi Bhushan, Bagchi S S

Abstract: High Concentrated Slurry Disposal (HCSD) of fly ash is currently being followed in many power plants in India. To evaluate the effectiveness of HCSD pump and slurry disposal system, density of fly ash and concentration of fly ash in the slurry being transported has to be known. Slurry percentage with its density is not provided by any original equipment manufacturer. Attempts have been made to obtain the slurry concentration and density for safe operation of HCSD pump. Inferences show that the specific gravity of fly ash varies from 1.9 to 2.25 and bulk density from 0.82 to 0.97 g/cc. The optimum ash percentage in slurry was found to be around 50 to 65% for any HCSD pump. Slurry density up to 1.44 g/cc with 65% slurry percentage (±1%) for fly ash of specific gravity 1.9-2.25 was found to be the safest for any HCSD pump operation.
