Opis

This text covers aspects of fluidization engineering and presents an examination of the applications in materials processing techniques. A separate chapter outlines the importance of fluidization engineering in high temperature processing, including an analysis of the fundamental concepts and applications of high temperature fluid bed furnaces for several advanced materials processing techniques. The authors provide: an analysis of fluidization in nuclear engineering and nuclear fuel cycles; an evaluation of advanced types of fluidized beds in materials processing, bioengineering, and downstream processing; an introduction to the fundamental principles and applications of fluidization engineering; a discussion of design aspects and modelling, incorporating distributor effects and flow regimes; a presentation of industrial applications with examples in extraction and process metallurgy; and a description of high temperature advanced fluid bed reactors.
