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 Trace Elements in Coal and Coal Combustion Residues written by Robert F. Keefer and published by CRC Press. This book was released on 2020-10-25 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace Elements in Coal and Coal Combustion Residues focuses on trace metal chemistry of coal and coal combustion residues. Special emphasis is placed on management of coal combustion residues in electric power plants and the influence of coal and associated residues on soils, plants, water, and animals. Topics covered include a brief summary of research sponsored by Electric Power Research Institute, environmental pollution from coal combustion plants in low-rainfall regions, accumulation of trace elements in freshwater mussels near a power plant, testing to evaluate fossil fuel wastes by chemicals and isotopes, transport of metals from coal piles and ash impoundments, leachability and toxicity of metals in fly ash, and plant absorption of chemicals from ash. The book will be a useful reference for environmental and reclamation consultants, environmental engineers, toxicologists, environmental regulatory personnel, officials with electric power utilities and water treatment plants, and soil scientists.

Download or read book Environmental Aspects of Trace Elements in Coal written by D.J. Swaine and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Happy he who could learn the causes of things (Virgil, Georgics 11) There is clearly a place for a book on the environmental aspects of trace elements in coal, especially with the increasing use of coal for power production. Our aim is to provide relevant background information and to update the situation regarding trace elements during beneficiation, combustion, .atmospheric deposition, leaching from wastes anti reclamation. The outcome is a balanced account of the overall situation. The initial chapter gives the rationale behind the planning of the book and puts the topics into the context of trace elements in the environment, while the final chapter summarises the subject matter and conclusions of each chapter. The choice of authors was based on their specialised knowledge. Although every effort has been made to ensure uniformity in layout, use of units, references and the like, authors have been given some latitude in expression and their styles have not been curbed. This book is intended primarily for coal scientists and technologists involved in environmental aspects of trace elements during the mining of coal, its beneficiation and usage, especially for power generation, and for regulatory bodies. It is considered to be suitable for relevant postgraduate courses. Just as it has been said that one of Bruckner's symphonies has enough melodies for a Beethoven to have written ten symphonies, so this book has several chapters that could be themes for other books.

Download or read book Leaching of Arsenic and Selenium from Fly Ash in the Simulated Field Systems written by Lenin P. Kasthuri and published by . This book was released on 2006 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fly ash accounts for nearly 60% of coal combustion products produced in the United States. Although fly ash is beneficially used in the cement and concrete industries, in waste stabilization, and as a structural fill, about 60% is disposed in landfills or ponds. Trace elements of major environmental concern such as As, Se, Hg, Cr, Cd, Ni, Pb, Cu, Co etc end up on fly ash particles as a result of coal combustion, which may be potentially released to the environment. For utilization purposes, fly ash is classified as class C or class F, depending primarily on its Si+Al+Fe content. The westernsub-bituminousminous coal typically produces class C fly ash, which is also higher in calcium than class F fly ash typically produced from eastern bituminous coal. Due to the differences in ash composition, the leaching behavior of trace elements varies between different types of fly ashes. In addition, activated carbon and ammonia may be used in power plants to control mercury and NOx emission, which also may affect trace element leaching. This study focused on the leaching potential of two major oxyanions of concern, arsenic and selenium, from different fly ashes under simulated field conditions. The results indicated that As and Se, which occur primarily as anionic species in water, were less leachable from the class C ash compared to the class F ash, at least partially due to the higher calcium content in the class C ash. Results also indicated that the mixing of class C ash and class F ash can significantly reduce the leaching of arsenic compared to the Class F ash alone. Activated carbon and ammonia based technologies do not seem to change the leaching characteristics of both arsenic and selenium from fly ash under natural conditions"--Abstract, leaf iv.

This book was released on 2018-05 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Occurrence and Distribution of Potentially Volatile Trace Elements in Coal: A Final Report The chemical nature of coal ash has been amply summarized in recent review articles (francis, 1961; Ode, 1963; Nicholls, 1968; watt, 1968; and Magee, Hall, and Varga, which deal in part with trace elements. However, research on trace elements in coal ash has not been extensive because until now they have been of little more than academic interest and because they occur in such small amounts that their determination is both costly and difficult.
