Heat Transfer in Fluidized Beds by O. Molerus,K.E. Wirth Pdf

This book provides a much needed and thorough treatment of the heat transfer in agitated disperse systems. It gives predictive equations for the heat transfer in moving beds, bubbling and circulating fluidized beds, pneumatic transport in vertical tubes and particulate fluidized beds. Owing to the many different modes of activation of heat transfer, the basic approach of the book is to provide experimental evidence of the relevance of particle motion to the proximity of solid surfaces for the heat transfer observed. This has been achieved by the evaluation of experiments obtained with a newly developed pulsed light method using luminous particles. Heat Transfer in Fluidized Beds will be of great use to students and researchers involved in heat transfer and thermodynamics.

Multiphase Flow by P. Vorobieff,C. A. Brebbia Pdf

The selected papers contained in this book present the latest research in one of the most challenging, yet most universally applicable areas of technology. Multiphase flows are found in all areas of technology and the range of related problems of interest is vast, including many areas of science and engineering. Recently multiphase fluid dynamics have generated a great deal of attention, leading to many notable advances in experimental, analytical and numerical studies. It is perhaps, however, work on numerical solutions which is the most noticeable owing to the continuing improvements in computer software tools. Progress in numerical methods has permitted the solution of many practical problems, helping to improve our understanding of the physics involved. The presented papers illustrate the close interaction between numerical modellers and researchers working to gradually resolve the many outstanding issues in our understanding of multiphase flow.

Fluidized Bed Combustion by Simeon Oka Pdf

A realization of recent clean energy initiatives, fluidized bed combustion (FBC) has quickly won industry preference due to its ability to burn materials as diverse as low-grade coals, biomass, and industrial and municipal waste. Fluidized Bed Combustion catalogs the fundamental physical and chemical processes required of bubbling fluidized beds before launching into application-centered coverage of hot-gas generator, incinerator, and boiler concepts and design, calculations for regime parameters and dimensions, and all aspects of FBC operation. It enumerates the environmental consequences of fluidized bed processes and proposes measures to reduce the formation of harmful emissions.

Heat Transfer in Fluidized Beds by O. Molerus,Karl-Ernst Wirth Pdf

A prestigious form of research grant in Germany is the Sonderforschungsbereich, which provides continuous funding over a period of up to 15 years, but only as long as the work is yielding worthwhile results. We acknowledge financial support of our work at Erlangen by the Deutsche Forschungsgemeinschaft (DFG), Sonder forschungsbereich 222. Thanks to this support, the experimental results from six Dr. -Ing. dissertations have provided the basis for our book: 8 • Schweinzer, J. (1987) Heat transfer in bubbling fluidized beds at Ar;a. 10 • Seiter, M. (1990) Particle motion and solids concentration in circulating fluidized beds • Mattmann, W. (1991) Heat transfer in pressurized circulating fluidized beds • Burschka, A. (1993) Pulsed light method • Dietz, S. (1994) Heat transfer in bubbling fluidized beds • Gruber, U. (1995) Heat transfer in lean phase systems This book is the result of the enthusiastic and trustful cooperation of its authors. Nevertheless, we are separate individuals. Chapters 1 to 12 and 19 are by O. Molerus; Chapters 13 to 18 are by K. -E. Wirth. This book came into existence after many rewrites, patiently endured by Mrs Winter, who typed all versions of the manuscript, and by Mrs Scheffler-Kohler, who drew all the figures. Bob Farmer and David Penfold helped us bridge the language gap to produce a readable book. Weare grateful to Professor Brian Scarlett of Delft University, who on behalf of Chapman & Hall allowed us to write this book.

Fluidized Bed Technologies for Near-Zero Emission Combustion and Gasification by Fabrizio Scala Pdf

Fluidized bed (FB) combustion and gasification are advanced techniques for fuel flexible, high efficiency and low emission conversion. Fuels are combusted or gasified as a fluidized bed suspended by jets with sorbents that remove harmful emissions such as SOx. CO2 capture can also be incorporated. Fluidized bed technologies for near-zero emission combustion and gasification provides an overview of established FB technologies while also detailing recent developments in the field. Part one, an introductory section, reviews fluidization science and FB technologies and includes chapters on particle characterization and behaviour, properties of stationary and circulating fluidized beds, heat and mass transfer and attrition in FB combustion and gasification systems. Part two expands on this introduction to explore the fundamentals of FB combustion and gasification including the conversion of solid, liquid and gaseous fuels, pollutant emission and reactor design and scale up. Part three highlights recent advances in a variety of FB combustion and gasification technologies before part four moves on to focus on emerging CO2 capture technologies. Finally, part five explores other applications of FB technology including (FB) petroleum refining and chemical production. Fluidized bed technologies for near-zero emission combustion and gasification is a technical resource for power plant operators, industrial engineers working with fluidized bed combustion and gasification systems and researchers, scientists and academics in the field. Examines the fundamentals of fluidized bed (FB) technologies, including the conversion of solid, liquid and gaseous fuels Explores recent advances in a variety of technologies such as pressurized FB combustion, and the measurement, monitoring and control of FB combustion and gasification Discusses emerging technologies and examines applications of FB in other processes

Fluidization, Solids Handling, and Processing by Wen-Ching Yang Pdf

This volume, Fluidization, Solids Handling, and Processing, is the first of a series of volumes on "Particle Technology". Particles are important products of chemical process industries spanning the basic and specialty chemicals, agricultural products, pharmaceuticals, paints, dyestuffs and pigments, cement, ceramics, and electronic materials. Solids handling and processing technologies are thus essential to the operation and competitiveness of these industries. Fluidization technology is employed not only in chemical production, it also is applied in coal gasification and combustion for power generation, mineral processing, food processing, soil washing and other related waste treatment, environmental remediation, and resource recovery processes. The FCC (Fluid Catalytic Cracking) technology commonly employed in the modern petroleum refineries is also based on fluidization principles.
