India has large reserves of coal and hence Power generation in India is predominantly based on using coal as the fuel. However, the quality of coal used at the thermal power stations is of poor quality and contains high level of coal ash. At present, the thermal power plants in the country produce close to 120 million t of coal ash. A significant quantity of this ash is used in various activities. Construction sector is one of the major consumers of this ash. Transportation of coal ash within the power plant and to the user’s site presents complex handling requirements. Moreover, the unused quantity has to be safely transported to the ash ponds. This paper considers various handling options for different grades of coal ash, which have been in use at the power stations in India.
