The book is edited with the contribution representing a range of industries in order to evaluate the industrial feasibility of each selected technology. It presents the most efficient solutions applied by ironmaking and steelmaking factories all around the world.




Gas-Solid Reactions


Book Description

Gas-Solid Reactions describes gas-solid reaction systems, focusing on the four phenomena—external mass transfer, pore diffusion, adsorption/desorption, and chemical reaction. This book consists of eight chapters. After the introduction provided in Chapter 1, the basic components of gas-solid reactions are reviewed in Chapter 2. Chapter 3 describes the reactions of individual nonporous solid particles, while Chapter 4 elaborates the reaction of single porous particles. Solid-solid reactions proceeding through gaseous intermediates are considered in Chapter 5. Chapter 6 deals with the experimental approaches to the study of gas-solid reaction systems. How information on single-particle behavior may be used for the design of multiparticle, large-scale assemblies, and packed- and fluidized-bed reaction systems is deliberated in Chapter 7. The last chapter covers the specific gas-solid reaction systems, including some statistical indices indicating the economic importance of the systems and processes it's based on. This publication is recommended for practicing engineers engaged in process research, development, and design in the many fields where gas-solid reactions are important.

Handbook of Thermoprocessing Technologies


Book Description

In Europe, thermoprocessing is the third largest energy consumption sector following traffic and room heating. Its structure is very much diversified and complex. Therefore it is split into a large number of subdivisions, each of them having a high importance for the industrial economy. Accordingly we find the application know-how for the design and the execution of respective equipment represented by a multitude of small but very specialized and significant companies and their experts. As a result there was only little chance to find a comprehensive survey of the practical side of this technology so far. This gap is now filled by the new "Handbook of Thermoprocessing Technologies" based on the contributions of many highly experienced, outstanding engineers working in this field. The main intention of this book is the presentation of practical thermal processing for the improvement of material and parts in industrial application. Additionally, a summary of respective thermal and material science fundamentals is given as well as basic fuel-related and electrical engineering knowledge for this technology and finally design aspects, components and safety requirements for the necessary heating installations are covered. In conclusion, a very wide and competent state of the art description is now available for all manufacturers and users of thermoprocessing equipment. But also specialists from neighbouring fields, students and all those who are generally interested in this important but widely unknown technology will find a quick survey here as well as a very profound expertise.







The Reduction of Iron Ores


Book Description

For the English edition the book was revised by the authors, taking into account a number of suggestions of the readers of the German edition. Some of the most important publications in the field of iron ore reduction, which appeared since 1967, have been used to bring the manuscript as far as possible up to date. The kind assistance of Dr. K. BOHNENKAMP of the Max-Planck-Institut fUr Eisenforschung, Dusseldorf, was much appreciated in this respect. Ohapters 2.9 and 2.10, dealing with the reduction of molten oxide slags by solid carbon and with the contribution of the water-gas reaction to iron ore reduction, have been added for the English edition. Ohapter 2.9 has been completely revised with the kind assistance of Dr. H. J. GRABKE, Stuttgart. Dipl.-Ing. J. LODDE contributed to this edition by revising the bibliography. Owing to the rapid development of the blast furnace it was necessary to revise Ohapter 5 considerably. In this field many valuable suggestions have been made by Dipl.-Ing. G. LANGE and Dipl.-Ing. P. HEINRICH. Furthermore, Ohapters3 and 4 have been thoroughly revised by Dr.-Ing. E. FORSTER and Dr.-Ing. U. SCHIERLOH. Last, but not least, we have to thank our translators for their excellent work.
