Study of Slurry Concentration in High Concentration Flyash Slurry Disposal System

摘要

High concentration flyash slurry is the flyash disposal system, that is followed in many coal based thermal power in India. It is important to measure the concentration of ash in the slurry being transported through slurry sample. Efforts to reduce the dilution of the slurry will result in energy conservation as well as water conservation. The latter is even more important to overcome the problem of excess water consumption. Attempts have been made to obtain the exact slurry concentration and water holding capacity of flyash through laboratory experiments. It is observed that the density of slurry varies from 1.17 to 1.60 for different concentration of the slurry and. water holding capacity of ash increases with the increase in ash concentration. Maximum possible water recovery is observed between 57-58% of total water used for above mentioned slurry concentration.
