Geotechnical Study on Behaviour of High Concentrated Ash Slurry

Abstract

Electric power generation in India has stepped up to numerous times in last decade and major portion of this power generation is coming from the coal based thermal plants. The chief by-product of thermal power plants are fly and bottom ashes. Transportation of ash slurry is a key problem in its efficient disposal. The foremost difficulty linked with ash slurry is that the particles settle down earlier than preferred. Lately, high concentrated slurry disposal (HCSD) structure has been hosted to get over of these problems. In this transportation system, ash slurry doesn’t only flow till it reaches the destination, but also settles down on the ash pond. This study describes the geotechnical properties of ash slurry of HCSD system in terms of densities, specific gravity, moisture content, and permeability. Change in properties of field tests with time are also shown in graphs. These studies and comparison with traditional mode of transportation will provide thorough understanding to the slurry disposal organization.
