Applications of Advanced Technology to Ash-Related Problems in Boilers


Book Description

This book addresses the behavior of inorganic material in combustion systems. The past decade has seen unprecedented improvements in understanding the rates and mecha nisms of inorganic transformations and in developing analytical tools to predict them. These tools range from improved fuel analysis procedures to predictive computer codes. While this progress has been met with great enthusiasm within the research community, the practices of the industrial community remain largely unchanged. The papers in this book were selected from those presented at an Engineering Foundation Conference of the same title. All have been peer reviewed. The intent of the conference was to illustrate the application of advanced technology to ash-related problems in boilers and, by so doing, engage the research and industrial communities in more productive dialog. Those attending the conference generally felt that we were successful on these counts. We also engaged the industrial community to a greater extent than ever before in the conference discussion and presentation. We hope these proceedings will facilitate a continued and improved interaction between industrial and research communities. Behavior of inorganic material has long been recognized as one of the major considerations affecting the design and operation of boilers that burn ash-producing fuels. The practical problems associated with the behavior are sometimes catastrophic and spec tacular, ranging from major slag falls that damage the bottom of furnaces to complete plugging of convection passes.

Developments in Thermochemical Biomass Conversion


Book Description

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.

Advances in Coal Spectroscopy


Book Description

The past decade has witnessed major advances in our understanding of the chemical composition, structure, and reactivity of the complex organic-rich fossil matter known as "coal. " Nevertheless, important scientific questions concerning molecular weight distributions, degree of crosslinking, typical duster sizes, type of interconnecting bridges, the possible role of a "mobile phase," and the nature of organic sulfur forms remain topics of heated debate. Moreover, there appears to be a notable lack of consensus regarding the overall direction and goals of structural elucidation work. Is it worthwhile to study whole coal samples, or should we separate out the various, more or less well-defined, maceral and mineral constituents before attempting to describe the structural and compositional features of coal at the molecular Ievel? Second, should there be more emphasis on key structural features and average statistical parameters, or is it necessary to identify individual chemical structures in considerable detail? From the developments of the past decade it is clear that advanced spectroscopic techniques are playing an increasingly important role in resolving difficult questions with regard to the chemical structure and composition of coal. Moreover, it has become equally clear that no single spectroscopic approach can provide all the answers but multiple techniques need to be used in a highly integrated and synergistic manner.




Incineration of Hazardous Waste


Book Description

Based on papers delivered at the First International Congress on Toxic Combustion By-products: Formation and Control, held in Los Angeles, Calif., August 1989. An overview of emissions, health risks, and existing regulations is followed by coverage of such topics as continuous emissions monitoring and control, processing of solids and liquids, fundamental chemistry, metals emissions, gas transport, and advanced combustion and control systems. Despite the length of time between the conference and publication, no index was prepared. Annotation copyright by Book News, Inc., Portland, OR
