The Fusibility Of Coal Ash And The Determination Of The Softening Temperature

Excerpt from The Fusibility of Coal Ash and the Determination of the Softening Temperature Although it is believed that this method will indicate the probable clinkering characteristics of a coal better than any fusion tests hereto fore described, the bureau does not recommend the general use of this method in coal Specifications until it is justified by actual trial in furnace tests of different coals. As no fusibility test of a well-mixed sample of the average ash of a coal takes into account the physical distribution of the impurities in the coal as burned, much additional investigation is needed to establish the exact relation of these labora tory fusibility tests to clinker formation. In order to correlate this proposed test of minimum softening temperature with clinker forma tion, the bureau is now making clinkering tests in a specially designed experimental furnace, in which different coals having ashes that differ in fusibility are burned under similar and known conditions of combustion. The results of this investigation will be published in a subsequent report. In the meantime it is hoped that other investigators will obtain similar correlation data.

All the guidance needed to test coal and analyze the results With the skyrocketing costs of most fuel sources, government, industry, and consumers are taking a greater interest in coal, an abundant and inexpensive alternative, which has been made more environmentally friendly through new technology. Published in response to this renewed interest, Handbook of Coal Analysis provides readers with everything they need to know about testing and analyzing coal. Moreover, it explains the meaning of test results and how these results can predict coal behavior and its corresponding environmental impact during use. The thorough coverage of coal analysis includes: * Detailed presentation of necessary standard tests and procedures * Explanation of coal behavior relative to its usage alongside the corresponding environmental issues * Coverage of nomenclature, terminology, sampling, and accuracy and precision of analysis * Step-by-step test method protocols for proximate analysis, ultimate analysis, mineral matter, physical and electrical properties, thermal properties, mechanical properties, spectroscopic properties, and solvent properties * Emphasis on relevant American Society for Testing and Materials (ASTM) standards and test methods, including corresponding International Organization for Standardization (ISO) and British Standards Institution (BSI) test method numbers To assist readers in understanding the material, a glossary of terms is provided. Each term is defined in straightforward language that enables readers to better grasp complex concepts and theory. References at the end of each chapter lead readers to more in-depth discussions of specialized topics. This is an essential reference for analytical chemists, process chemists, and engineers in the coal industry as well as other professionals and researchers who are looking to coal as a means to decrease dependence on foreign oil sources and devise more efficient, cleaner methods of energy production.
