Book excerpt: The main use of coal in India is for generation of electricity, both currently and apparently also in the future. In India approximately 70% of power generation has been through coal-fired thermal power plants. About 60% of produced coal is used for power generation. The coal which is used in power plants has an ash content of about 30-50%. The Coal Ash Administration that was established in 1993 with the objective of coordinating the effort at a national level to solve the problem of ash accumulation at the power plants, chose to deal with the problem by advancing the use of coal ash as a resource having economic value, in various sectors, as is done in most of the developed countries in the world. This site is intended to provide information regarding coal ash characteristics, beneficial uses of coal ash, both currently and in the future, in construction, infrastructures, industry and agriculture in India, to provide information on environmental quality issues, and to describe what is being done in this area to prevent damage to the environment and to improve it. Since coal fly ash consists of predominantly silt-sized particles, there is sometimes a concern about the possible frost susceptibility of fly ash as an embankment or structural backfill material, which can provide scope for environmentally safe. The major challenge with the introduction of the fly ash is its generation in unmanageable volumes which creates environmental problems in terms of land degradation, and degradation of air and water quality. The problem of storage and disposal of the fly ash creates a considerable pressure on land availability particularly in a densely populated country like India. Many researchers are working towards the large scale utilization of fly ash. The approaches include intermixing the fly ash with cement for civil construction work, manufacture of bricks, and utilization as a road pavement material and application as soil amendment medium for the plant growth.

Download or read book Chemistry of Trace Elements in Fly Ash written by Kenneth S. Sajwan and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accumulation of large amounts of ash from fossil fuel combustion for electric power plant generation is becoming a major environmental concern in the United States. Furthermore, stringent environmental regulations mandated by the Environmental Protection Agency through the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, as well as state and local environmental regulations may result in even more ash production with subsequent contact with the environment. The concentrations of trace elements in coal residues are extremely variable and depend on the composition of the original coal, conditions during combustion, the efficiency of emission control devices, storage and handling ofbyproducts, and climate. The research papers in this book were presented as a part of the Sixth International Conference on the Biogeochemistry of Trace Elements held at the University of Guelph, Ontario, Canada, from July 29-August 2, 2001. The purpose of this corit'erence was to present current knowledge on the source, pathways, behavior and effects of trace elements in soils, waters, plants and animals. In addition, the book also includes invited research papers from scientists who have done significant research in the area of coal and coal combustion byproducts. All the research papers presented herein have been subjected to peer review.

Download or read book Combustion Byproducts Recycling Consortium written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year, over 100 million tons of solid byproducts are produced by coal-burning electric utilities in the United States. Annual production of flue gas desulfurization (FGD) byproducts continues to increase as the result of more stringent sulfur emission restrictions. In addition, stricter limits on NOx emissions mandated by the 1990 Clean Air Act have resulted in utility burner/boiler modifications that frequently yield higher carbon concentrations in fly ash, which restricts the use of the ash as a cement replacement. Controlling ammonia in ash is also of concern. If newer, 'clean coal' combustion and gasification technologies are adopted, their byproducts may also present a management challenge. The objective of the Combustion Byproducts Recycling Consortium (CBRC) is to develop and demonstrate technologies to address issues related to the recycling of byproducts associated with coal combustion processes. A goal of CBRC is that these technologies, by the year 2010, will lead to an overall ash utilization rate from the current 34% to 50% by such measures as increasing the current rate of FGD byproduct use and increasing in the number of uses considered 'allowable' under state regulations. Another issue of interest to the CBRC would be to examine the environmental impact of both byproduct utilization and disposal. No byproduct utilization technology is likely to be adopted by industry unless it is more cost-effective than landfilling. Therefore, it is extremely important that the utility industry provide guidance to the R & D program. Government agencies and private-sector organizations that may be able to utilize these materials in the conduct of their missions should also provide input. The CBRC will serve as an effective vehicle for acquiring and maintaining guidance from these diverse organizations so that the proper balance in the R & D program is achieved.
Download or read book Environmental Implications of Expanded Coal Utilization written by M.J. Chadwick and published by Elsevier. This book was released on 2013-10-22 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Implications of Expanded Coal Utilization focuses on the increasing consideration of coal as an alternative source of energy. This book comes as an answer to the issues on health and environment regarding the extraction, production, and use of coal. Composed of nine chapters, the selection starts by underlining the potential prospects for coal, which plays a vital role in meeting energy demands. The book also shows that problems have evolved regarding the use of coal, including land disturbance and increased land occupation due to mining. The text also notes that the international trade of coal will surely generate waste products, and some of which can be the result of poor transportation and handling. The book focuses on coal gasification and liquefaction and emphasizes that the processes involved must be carefully understood in order to avoid the environmental impacts of coal use. Attempts have been made to establish a conceptual framework to be used in assessing the health and environmental health impacts of the conversion and utilization of coal. Relative to this, discussions that follow include the trace elements that are the products of coal combustion and conversion and also coal derived carbon compounds. Another sector is focused on the evaluation of the effects of emissions on human health, especially of workers in the industry. The effects of the utilization of coal on communities are also considered. The text is a vital source of information to those involved in the research on the use of coal as alternative source of energy.

Available in PDF, EPUB and Kindle. Book excerpt: The long-term future for coal looks bleak. The recent UN climate change conference in Paris called for an end to the use of fossil fuels. However, coal remains one of the world’s most important sources of energy, fuelling more than 40% of electricity generation worldwide, with many developing nations relying almost wholly on coal-fuelled electricity. Coal has been the fastest growing energy source in recent years and is essential for many industrial activities, but the coal industry is hugely damaging for the environment. A major driver in climate change and causing around 40% of the world’s carbon dioxide emissions, coal fuel comes at a high environmental price. Furthermore, mining and air pollution kill thousands each year. A timely addition to the series, this book critically reviews the role of coal in the 21st century, examining energy needs, usage and health implications. With case studies and an examination of future developments and economics, this text provides an essential update on an environmental topic the world cannot ignore.
