Download or read book The Impact Of Ash Deposition On Coal Fired Plants written by Jim Williamson and published by Taylor & Francis. This book was released on 2022-10-12 with total page 1103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal provides almost 40% of the world's electricity, and despite the understandable concern with respect to the environmental impact associated with coal use, forecasts from the International Energy Agency predict, that worldwide coal use will increase by up to 2% per annum until the year 2OlO. Faced with this increase, it is clearly important that the most efficient and environmentally acceptable clean coal technologies are available. This book is comprised of the proceedings of the Engineering Foundation Conference held in June 1993 in England. The objective of the conference was to present ideas on methods of predicting and reducing the effects of ash deposition in coal conversion systems, highlighting the problems experienced in industry, considering both utilities and industrial plants, and providing a view of the technology of coal ash deposition and its impact. Better techniques are needed to reduce the impact of ash deposition in coal fired plants, and these proceedings should form a reference document for anyone either experiencing slagging or actively engaged in trying to understand or eliminate the phenomenon.

Download or read book Ash Formation Under Pressurized Pulverized Coal Combustion Conditions written by Aura Cecilia Davila Latorre and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal combustion is a source of inorganic particulate matter (ash), which can deposit in boilers and also be emitted into the atmosphere becoming part of ambient fine particulate matter (PM 2.5). In order to decrease coal combustion emissions per unit of power produced, higher efficiency systems have been proposed, including systems operating at elevated pressures. These new operating conditions will affect pollutant formation mechanisms, particularly those associated with the conversion of mineral matter to ash. Ash particle formation mechanisms are particularly sensitive to changes in pressure as they are related to the structure of coal char particles at early stages of combustion. To assess the importance of pressure on ash particle formation, pyrolyzed chars and ash particles from pressurized pulverized combustion of two bituminous and one subbituminous U.S. coals at operating pressures up to 30 atm were studied. Pressure changes the distribution of char particle types, changing the spatial distribution of the minerals during the combustion process and therefore affecting particle formation mechanisms. Chars were examined by Scanning Electron Microscopy (SEM) and classified into two different types (cenospheric and solid) depending on porosity and wall thickness. A correlation for estimating the amount of these cenospheric char particles was then proposed for bituminous coals based on the operating conditions and coal maceral analysis. The ash particle size distribution of the coals combusted at different operating pressures was measured using Computer Controlled Scanning Electron Microscopy (CCSEM). The results of the char characterization and ash particle size distribution measurements were then incorporated into an ash particle formation algorithm that was proposed and implemented. The model predicts ash particle size and composition distributions at elevated pressures under conditions of complete char burnout. Ash predictions were calculated by first developing char structure distribution functions based on coal characteristics. To obtain an ash particle size distribution, carbon is then allowed to react away while following coalescence, fragmentation and other transformation processes as combustion proceeds. Particle size distributions calculated with this model showed qualitative agreement with the trends identified in the experimental portion of this research.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal ash, and particularly fine fly ash, remain one of the principal practical and environmental problems in coal-based power generation. In particular, submicron aerosols are identified with direct inhalation risk. Submicron ash is thought to arise from mineral vaporization during char combustion, followed by nucleation, condensation and coagulation to yield an aerosol. While aerosols are predominantly made out of volatile alkali minerals, they also can include refractory oxides that are chemically reduced to more volatile forms within the char particle and vaporized. Most of the ash of size greater than 1[mu]m is generated by agglomeration of mineral as the char particle bums out. These two principal mechanisms are thought to account for most of the ash generated in coal combustion. Previous research has shown that various forms of coal treatment can influence the yields of fine ash from combustion. The research reported here investigates various forms of treatment, including physical coal cleaning, aerodynamic sizing, degree of grinding, and combinations of these on both aerosol yields and on yields of fine residual ash (1-4[mu]m). The work also includes results from the combustion of artificial chars that include individual mineral elements. This research shows that these various forms of coal treatment can significantly change ash characteristics. While none of the treatments affected the bulk of the residual ash size distribution significantly, the yield of the ash aerosol mode (d

This book was released on 2013-11-21 with total page 1630 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been many developments in the science and technology of thermo chemical biomass conversion since the previous conference on Advances in Thermochemical Biomass Conversion in Interlaken, Switzerland, in 1992. This fourth conference again covers all aspects of thermal biomass conversion systems from fundamental research through applied research and development to demon stration and commercial applications to reflect the progress made in the last four years. All aspects of bioenergy systems are covered from pretreatment through to end-user applications with increased consideration paid to the environmental benefits and problems of implementing bio-energy systems. There was an excellent response with over 200 papers offered and over 180 delegates from 29 countries attending the conference. The programme was divided into five main areas covering pyrolysis, pretreatment, gasification, combustion and system studies and this division is reflected in the structure of these conference proceedings. Each main section was preceded by a state-of-the-art review to provide a focus for the ensuing presentations and an authoritative reference. All the papers included have been subject to a full peer review process. As with any international conference, an important aim was to exchange ideas and discuss problems with fellow researchers, as well as to hear about the latest research and development and applications. A workshop programme was included to encourage this interaction in areas of interest selected by participants. The resul tant workshop reports provide a summary of topical problems and opportunities.

Subcommittee on Rural Development, Entrepreneurship, and Trade and published by . This book was released on 2010 with total page 204 pages. Available in PDF, EPUB and Kindle. 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.
