Available in PDF, EPUB and Kindle. Book excerpt: This is a print on demand edition of a hard to find publication. Coal combustion waste (CCW) is inorganic material that remains after pulverized coal is burned for electricity production. Industry estimates that as much as 136 million tons were generated in 2008. On Dec. 22, 2008, national attention was turned to the waste when a breach in an impoundment pond at the TVA¿s Kingston, TN, power plant released 1.1 billion gallons of coal ash slurry. The cleanup cost may reach $1.2 billion. Contents of this report: (1) Intro.; (2) Overview of EPA¿s Proposal; (3) The Nature of CCW; (4) CCW Management Methods; (5) Risks Associated with CCW Mis-Management; (6) RCRA Provisions Relevant to EPA¿s Proposal (7) EPA¿s Proposed Regulatory Options; (8) Types of Coal Combustion Waste.

Download or read book Solid Biofuels for Energy written by Panagiotis Grammelis and published by Springer Science & Business Media. This book was released on 2010-10-22 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fossil fuels are widely used for electricity generation and heating, creating greenhouse gas emissions and other toxic pollutants, which should be minimised according to the most recent environmental legislation. The utilisation of solid fuels with biogenic origin could contribute to the minimisation of these emissions. Solid Biofuels for Energy presents the current status of the engineering disciplines in this specific area, providing an improved background on the energy exploitation options of solid biomass. Within this framework, all thematic priorities related to the solid bioenergy potential and standardisation, commercialised and emerging energy technologies, and quality of solid residues are presented. Special attention has been given to biomass co-firing with coal, since it has the highest potential for commercial application, while combustion and gasification are more promising for units of medium to small scale. This strong practical focus is evident throughout the book, particularly in discussions of: • international standards for solid biofuel specifications; • supply, cost and sustainability of solid biofuels; • technical issues and non-technical barriers in biomass/coal co-firing; and • biomass combustion and gasification characteristics. Solid Biofuels for Energy is an informative reference, written for researchers and postgraduate students working in the field of biomass. It can also be a useful guide for chemical and mechanical engineers, involved in the environment and energy production sectors.
Download or read book Managing Coal Combustion Residues in Mines written by National Research Council and published by National Academies Press. This book was released on 2006-08-14 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Burning coal in electric utility plants produces, in addition to power, residues that contain constituents which may be harmful to the environment. The management of large volumes of coal combustion residues (CCRs) is a challenge for utilities, because they must either place the CCRs in landfills, surface impoundments, or mines, or find alternative uses for the material. This study focuses on the placement of CCRs in active and abandoned coal mines. The committee believes that placement of CCRs in mines as part of the reclamation process may be a viable option for the disposal of this material as long as the placement is properly planned and carried out in a manner that avoids significant adverse environmental and health impacts. This report discusses a variety of steps that are involved in planning and managing the use of CCRs as minefills, including an integrated process of CCR characterization and site characterization, management and engineering design of placement activities, and design and implementation of monitoring to reduce the risk of contamination moving from the mine site to the ambient environment. Enforceable federal standards are needed for the disposal of CCRs in minefills to ensure that states have adequate, explicit authority and that they implement minimum safeguards.

Book excerpt: "The subcommittee has called this hearing so that members might learn more about coal ash, the small businesses that turn coal ash into useful products and the concerns that these businesses have about the proposed Federal regulations that they believe may have a negative effect on their industry ... The EPA has recently issued two proposals for regulating coal ash. One would regulate coal ash as a solid waste and would provide very limited Federal enforceability and may not provide adequate protection of the environment and human health. The other would list coal ash as a special waste under the Hazardous Waste Subtitle in the Resource Conservation and Recovery Act, Subtitle C. The second option is one that we will focus on ... since it has generated great concerns among small businesses across this country. These businesses, many of which are represented here today, have reason to believe that regulating coal ash under Subtitle C, even as a special waste, will open recycling operations to added litigation and a stigma that will discourage the ... use of the products made with recycled coal ash."--P. 1-2.

Download or read book Performance and Economics of Co firing a Coal written by and published by . This book was released on 1996 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study's objective was to investigate co-firing a pressurized fluidized-bed combustor with coal and refuse-derived fuel for the production of electricity and the efficient disposal of waste. Performance evaluation of the pressurized fluidized-bed combustor (PFBC) power plant co-fired with refuse-derived fuel showed only slightly lower overall thermal efficiency than similar sized plants without waste co-firing. Capital costs and costs of electricity are within 4.2 percent and 3.2 percent, respectively, of waste-free operation. The results also indicate that there are no technology barriers to the co-firing of waste materials with coal in a PFBC power plant. The potential to produce cost-competitive electrical power and support environmentally acceptable waste disposal exists with this approach. However, as part of technology development, there remain several design and operational areas requiring data and verification before this concept can realize commercial acceptance. 3 refs., 3 figs., 4 tabs.

Download or read book Coal Combustion Residue written by Frank Rusco and published by DIANE Publishing. This book was released on 2010-06 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: On Dec. 22, '08, a breach in a surface impoundment (or storage pond) dike at the TVA Kingston Fossil Plant in TN resulted in the release of 5.4 million cubic yards of coal ash -- also referred to as coal combustion residue (CCR) -- into the Emory River. The spill covered 300 acres and made 3 homes uninhabitable; it damaged 23 other homes, plus roads, rail lines, and utilities. The cleanup will cost a billion dollars and take 2 to 3 years to complete. This report identifies: (1) the number of surface impoundments for storing CCR in the U.S. and their location; (2) problems, if any, with the storage of coal ash, and how those problems are being addressed; and (3) the type of fed. oversight that exists for CCR and what, if any, issues need to be resolved.

Download or read book Co Firing of Waste with Coal in a Fluidised Bed Combustor written by Suthum Patumsawad and published by LAP Lambert Academic Publishing. This book was released on 2010-04 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights on the co-firing of MSW in a fluidised bed combustor in terms of combustion efficiency and characteristics to assess the potential advantages offered by fluidised bed combustors over conventional methods of burning. The influence of various combustor operation parameters on the combustion efficiency and characteristics is determined. However, wastes are variable in nature, the combustion conditions suitable for one particular type of waste may not be so for another type. Hence the combustion efficiencies and compatibility of different wastes in a fluidised bed combustor operating under given sets of conditions is one area of investigation. A comparison of the experimental results obtained from the combustion of coal with co-firing waste with coal under equivalent conditions is made and the effect of the combustion characteristics of co-firing waste with coal is also investigated. Co-firing in FBC demonstrates the capability of supplement either MSW or other high moisture content wastes efficiently in existing coal-fired boilers with minimum modification.
