Book Description
This book contains papers presented at the Engineering Foundation Conference on mineral matter in fuels held on November 2-7, 1997 in Kona, Hawaii. The conference is one of a continuing series that was initiated by the CEGB Mar- wood Engineering Laboratories in 1963. The conference was to be eventually organised by the Engineering Foundation as the need for multi-disciplinary work related to c- trolling ash effects in combustors became apparent. The conference covers both the science and the applications. The papers also present case histories, particularly for current fuel technologies, developments in advanced technologies for power generation and mathematical modelling of these processes. Developments since 1963 have been slow, but steady, due to the complexity of the chemical and physical processes involved. However, the research presented here displays great improvement in our understanding of the mechanisms by which mineral matter will influence fuel use. Steve Benson from EERC presented a review and current status of issues related to ash deposition in coal combustion and gasification. The application of new analytical tools, which have been detailed in the previous conferences, is presented. These include CCSEM, as well as new techniques for char- terising sintering of ash, such as TMA, image analysis, X-ray diffraction crystallography and thermal analysis. The new analytical techniques were extended to encompass widely differing fuels such as biomass. Ole H Larsen from ELSAM Denmark presented a review of these advanced techniques.

Book Description
Trace Elements in Coal focuses on the compositions, reactions, and properties of trace elements in coal. The book first discusses the origin of trace elements in coal. The formation of peat; geological and geochemical aspects of coal seams; geology of Australian coals; constitution of coal; history of trace elements in coal; and coal mining in Australia are discussed. The text also clarifies the mode of occurrence of trace elements in coal. The identification of minerals in coal; silicon-rich minerals; carbonate minerals; sulfide minerals; lignites and brown coals; and phosphates are discussed. The book then underscores the methods of analysis. Inductively coupled plasma atomic emission spectrometry; atomic absorption spectrometry; spark source mass spectrometry; and neuron activation analysis are described. The text also focuses on the contents of trace elements in coal; comparisons of coal with shale and soil; relationship of radioactivity and coal; and relevance of trace elements in coal. The book is a good source of data for readers wanting to study the trace elements in coal.

Book Description
Providing a comprehensive survey of the origin, the fundamental properties, and the technology of utilization of the lignites of North America, this book will be of particular interest to professional scientists and engineers working in coal research or coal technology. Coals display a continuum of properties, often with no sharp, steep change between ranks and thus the book restricts the discussion strictly to lignites (with the occasional comparisons with other coals).There is a very extensive index, making the contents of the book easily accessible to the reader.

Book Description
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.

Book Description
Rund ein Viertel des weltweiten Energieverbrauchs wird mit Kohle bestritten, und von der weltweit geförderten Kohle werden ca. 65 % an Stromerzeuger und 33 % an industrielle Abnehmer geliefert, wobei der Rest überwiegend an Verbraucher im privaten und gewerblichen Bereich geht. Es wird erwartet, dass der Anteil der Kohle am gesamten Energieverbrauch weltweit bis 2035 auf knapp 30 % steigt. Dieses Werk beschreibt die Herausforderungen und die einzelnen Schritte bei der Energieproduktion aus Kohle und befasst sich mit den Herausforderungen beim Umgang mit Umweltschutzbedenken gegen die Nutzung von Kohle in den Kraftwerken der Zukunft. Es werden neue Technologien beschrieben, mit denen die Freisetzung von schädlichen Schwefel-, Stickstoff- und Quecksilberpartikeln bei der Verbrennung von Kohle zur Stromerzeugung nahezu eliminiert werden kann. Außerdem wird beschrieben, mit welchen Technologien sich die von den Kohlekraftwerken ausgestoßenen Treibhausgase abscheiden lassen und wie es möglich ist zu verhindern, dass diese Emissionen zur globalen Erwärmung beitragen. Das Buch ist von einem der weltweit führenden Energieexperten verfasst und ist ein absolutes Muss für alle Ingenieure, Wissenschaftler und Studierenden in diesem Fachbereich, denn es dient als wertvolles Nachschlagewerk und Leitfaden in einem sich rasch verändernden Umfeld.

Book Description
This book is an integrated approach towards the applications of coal (organic) petrology and discusses the role of this science in the field of coal and coal-related topics. Coal petrology needs to be seen as a continuum of organic (macerals) and inorganic (minerals and trace elements) contributions to the total coal structure, with the overprint of coal rank. All this influences the behavior of coal in utilization, the coal by-products, the properties of coal as a reservoir for methane or a sequestration site for carbon dioxide, and the relationships of coal utilization with health and environmental issues. The interaction of coal properties and coal utilization begins at the mine face. The breakage of the coal in mining influences its subsequent beneficiation. Beneficiation is fundamental to the proper combustion of coal and is vital to the preparation of the feedstock for the production of metallurgical coke. An understanding of basic coal properties is important for achieving reductions in trace element emissions and improving the efficiency of combustion and combined-cycle gasification. The production of methane from coal beds is related to the properties of the in situ coal. Similarly, coal bed sequestration of carbon dioxide produced from combustion is dependent on the reservoir properties. Environmental problems accompany coal on its way from the mine to the point of utilization and beyond. Health aspects related with coal mining and coal utilization are also included because, in planning for coal use, it is impossible to separate environmental and health issues from the discussion of coal utilization. The book is aimed at a wide audience, ranging from researchers, lecturers and students to professionals in industry and discusses issues (such as the environmental, and health) that are of concern to the general public as a whole. - This book focuses on the applications of coal (organic) petrology to our modern society - It is an integrated approach to help the reader appreciate the importance of coal quality and coal utilization. Coal composition (macerals, mineral, trace elements) and the overprint of coal rank are treated together - The book synthesises all the possibilities of the organic petrology as a tool for coal utilization in conventional applications (mining and beneficiation, coal combustion, gasification, liquefaction, carbonization), as a precursor of carbon materials and as a petroleum source and reservoir rock - The role of applied petrology in the characterization of solid by-products from coal utilization is also discussed - In addition, this book describes the present status of environmental and health problems linked to coal utilization and the ways in which such problems might be overcome in the future
