Efforts to examine coal and fly ash

Abstract

Fossil fuels have met a large portion of the world's ever-increasing energy demands as technology has progressed. Coal-burning in thermal power plants releases gaseous and particulate pollution into the environment, as explained in previously. During the coal-burning fuel cycle, many constituents are released into the atmosphere. India's thermal power plants account for 65 percent of installed capacity and 70 percent of the country's total energy output. The current installed capacity in India, including power utilities, is roughly 90,000 MW. More than 150 million tonnes of coal are currently consumed by thermal power plants in the United States. By 2001, the ratio of thermal power stations is predicted to rise to 75 percent. As a result of the recent liberalization, several thermal power projects are being planned. It is expected that these capabilities will be completely realized during the next five to 10 years. The ash content of Indian coals has been reported to range from 35% to 55%. In general, the ash component makes up about half of the entire weight. 75 thermal power plants in the country generate more than 60 million tonnes of fly ash per year. [2-3].
