Book excerpt: "Due to rising energy demand, the amount of coal utilization is escalating at a fast rate, leading to a rise in ash generation. Coal Fly Ash: Properties, Applications and Performance begins by presenting a study wherein the physiochemical properties of coal ash were analysed and based on that, their potential for reuse was identified. Next, the synergy between Portland cement and coal fly ash was investigated. Raw materials were characterized in terms of chemical and mineralogical composition and physical properties. Mortars were manufactured and the effect of the addition of different ratios of coal fly ash (0-80 wt %) as a partial substitute of Portland cement was studied. Following this, an investigation was carried out to explore the behaviour of coal ash with hydrated lime as mineral filler in hot mix asphalt, in an attempt to determine a sustainable solution for the management of coal ash in Mauritius. The closing chapter describes the synthesis process used to obtain zeolite Na-A from coal fly ash via fusion with NaOH followed by hydrothermal reaction. Coal fly ash is a low cost source of both silica and alumina. The molar ratio of SiO2/Al2O3 for zeolite 4A formation was achieved through the addition of sodium aluminate solution/aluminum waste as aluminum sources"--

Download or read book Circular Economy and Fly Ash Management written by Sadhan Kumar Ghosh and published by Springer Nature. This book was released on 2019-10-25 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a number of innovative uses of fly ash. Fly ash is a fine powder that is a byproduct of burning pulverized coal in thermal power plants. It is a pozzolan – a substance containing aluminous and siliceous material that when mixed with lime and water forms a compound similar to Portland cement. Though fly ash was a problem in terms of its disposal, it now has a variety of uses, such as a prime material in blocks, bricks, and PCC paving, and further applications are being investigated. As such, the recovery and reuse of fly ash wastes plays an important role in the implementation of the circular economy concept. Featuring selected, high-quality research papers presented at IconSWM 2018, the book provides valuable insights for the recycling industries, power plants, researchers, and governments.

Download or read book Fly Ash written by Peter H. Telone and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fly ash is one of the residues generated in the combustion of coal. Fly ash is generally captured from the chimneys of coal-fired power plants, and is one of two types of ash that jointly are known as coal ash; the other, bottom ash, is removed from the bottom of coal furnaces. Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline) and calcium oxide (CaO). Toxic constituents include arsenic, beryllium, boron, cadmium, chromium, chromium VI, cobalt, lead, manganese, mercury, molybdenum, selenium, strontium, thallium, and vanadium, along with dioxins and PAH compounds. In the past, fly ash was generally released into the atmosphere, but pollution control equipment mandated in recent decades now require that it be captured prior to release. In the US, fly ash is generally stored at coal power plants or placed in landfills. About 43 percent is recycled, often used to supplement Portland cement in concrete production. It is increasingly finding use in the synthesis of geopolymers and zeolites.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Organic Farming: Agronomic Soil Management Practices focuses on the integrated interactions between soil-plant-microbe-environment elements in a functioning ecosystem. It explains sustainable nutrient management under organic farming and agriculture, with chapters focusing on the role of nutrient management in sustaining global ecosystems, the remediation of polluted soils, conservation practices, degradation of pollutants, biofertilizers and biopesticides, critical biogeochemical cycles, potential responses for current and impending environmental change, and other critical factors. Organic farming is both challenging and exciting, as its practice of "feeding the soil, not the plant provides opportunity to better understand why some growing methods are preferred over others. In the simplest terms, organic growing is based on maintaining a living soil with a diverse population of micro and macro soil organisms. Organic matter (OM) is maintained in the soil through the addition of compost, animal manure, green manures and the avoidance of excess mechanization. - Presents a comprehensive overview of recent advances and new developments in the field OF research within a relevant theoretical framework - Highlights the scope of the inexpensive and improved management practices - Focuses on the role of nutrient management in sustaining the ecosystems

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.
