《理想和无气泡流态化》主要内容：When fluidization was first employed industrially,e.g., in the Winkler gasifier, we had only the bubblingfluidized bed as shown in the middle diagram of thefigure, in which gas bypasses as bubbles, thus leadingto poor solid-gas contact and incurring large pressuredrop. What is ideal is the high dispersion of solidsshown asthe background of the book jacket. Short ofsuch an ideal state, we may resort to suppressing bubblesby the use of shallow fluidized bed as shown on thelefthand side diagram achieved through reducing thesolid content of the fluidized bed. or the fast fluidizedbed with continuous recycfing of solids to the bottomof the bed, as shown on the righthand side diagram. Allthese diagrams of fluidization were generated throughcomputer modeling by Professor Wei Ge, and fromhosts of these diagrams, four were selected by Xue Bai,Jianxing Lu and Ying Ren to portray the principal thesisof this book.
