Download or read book Circulating Fluidized Beds written by J.R. Grace and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the late 1970s there has been an explosion of industrial and academic interest in circulating fluidized beds. In part, the attention has arisen due to the environmental advantages associated with CFB (circulating . fluidized bed) combustion systems, the incorporation of riser reactors employing cir culating fluidized bed technology in petroleum refineries for fluid catalytic cracking and, to a lesser extent, the successes of CFB technology for calcina tion reactions and Fischer-Tropsch synthesis. In part, it was also the case that too much attention had been devoted to bubbling fluidized beds and it was time to move on to more complex and more advantageous regime,S of operation. Since 1980 a number of CFB processes have been commercialized. There have been five successful International Circulating Fluidized Bed Confer ences beginning in 1985, the most recent taking place in Beijing in May 1996. In addition, we have witnessed a host of other papers on CFB funda mentals and applications in journals and other archival publications. There have also been several review papers and books on specific CFB topics. However, there has been no comprehensive book reviewing the field and attempting to provide an overview of both fundamentals and applications. The purpose of this book is to fill this vacuum.

Download or read book Fluidization Solids Handling and Processing written by Wen-Ching Yang and published by Elsevier. This book was released on 1998-12-31 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Modeling of a Fluidized Bed Combustor with Immersed Tubes written by S. C. Saxena and published by . This book was released on 1977 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress is reported in the development of a mathematical model of a fluidized-bed combustor. The model will include coal combustion phenomena and will incorporate basic mass transport relationships, bubble mechanics, heat transfer and configuration effects. A cold model test bed will be designed, constructed and operated to generate data in support of the effort in developing the mathematical model. In particular, experiments will provide data concerning heat transfer effects of tubes and tube bundles in fluidized beds, bubble formation, dispersion etc. Experiments have been carried out to measure the total heat transfer coefficient between 12.7 mm diameter copper tubes with different surface roughness and glass beads of different sizes. The comparison of results for the rough and technically smooth tubes revealed that the heat transfer coefficient strongly depends on the ratio of pitch (P) to particle diameter anti d/sub p/). By the proper choice of this ratio, P/anti d/sub p/, the total maximum heat transfer coefficient could be increased by as much as 40% over the value for a smooth tube with the same outside diameter. However, if P/anti d/sub p/ ratio is less than unity, the maximum heat transfer coefficient for rough tube is smaller as compared to the smooth tube. The design of the two end plates of the fluidized bed for mounting tube bundles of varying configuration and pitches has been completed and is currently under fabrication in the departmental workshop.

Download or read book Fluidized Bed Combustion written by Simeon Oka and published by CRC Press. This book was released on 2003-09-16 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Scaling of Pressurized Fluidized Beds written by and published by . This book was released on 1994 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project has two primary objectives. The first is to verify a set of hydrodynamic scaling relationships for commercial pressurized fluidized bed combustors (PFBC). The second objective is to investigate solids mixing in pressurized bubbling fluidized beds. American Electric Power's (AEP) Tidd combined-cycle demonstration plant will provide time-varying pressure drop data to serve as the basis for the scaling verification. The verification will involve demonstrating that a properly scaled cold model and the Tidd PFBC exhibit hydrodynamically similar behavior. An important issue in PFBC design is the spacing of fuel feed ports. The feed spacing is dictated by the fuel distribution and the mixing characteristics within the bed. After completing the scaling verification, the cold model will be used to study the characteristics of PFBCs. A thermal tracer technique will be utilized to study mixing both near the fuel feed region and in the far field. The results allow the coal feed and distributor to be designed for optimal heating.
Download or read book Flat Panel Display Technologies written by Lawrence E. Tannas and published by William Andrew. This book was released on 1995-12-31 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large scale manufacturing of liquid crystal flat panel displays (LCDs) by Japan brought the world's attention to the existence of an enormous market potential exists when there are alternatives to the cathode ray tube (CRT). The Japanese have recognized that new display technologies are critical to making their products highly competitive in the world market. The CRT is losing market share to the solid-state flat panel display. Japan currently holds 90% of the market, and this book outlines opportunities in the former Soviet Union, where companies with the necessary technology are seeking partners, investment, and manufacturing opportunities. Entire cities that were once not even on the map due to their military mission, are now appearing, filled with state-of-the-art electronic technology. The book is developed from the reports issued by investigators based on their field visits to 33 sites in Japan, and 26 sites in Russia, Ukraine, and Belarus.
