Book Synopsis Fluidized Bed Technologies for Near-Zero Emission Combustion and Gasification by : Fabrizio Scala
Download or read book Fluidized Bed Technologies for Near-Zero Emission Combustion and Gasification written by Fabrizio Scala and published by Elsevier. This book was released on 2013-09-30 with total page 1091 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Advanced integrated gasification combined cycle (IGCC) power systems require the development of high-temperature desulfurization sorbents capable of removing hydrogen sulfide from coal gasifier down to very low levels. The objective of this investigation was to identify and demonstrate methods for enhancing the long-term chemical reactivity and mechanical strength of zinc ferrite, a leading regenerable sorbent, for fluidized-bed applications. Fluidized sorbent beds offer significant potential in IGCC systems because of their ability to control the highly exothermic regeneration involved. However, fluidized beds require a durable, attrition-resistant sorbent in the 100--300 [mu]m size range. A bench-scale high-temperature, high- pressure (HTHP) fluidized-bed reactor (7.6-cm I.D.) system capable of operating up to 24 atm and 800°C was designed, built and tested. A total of 175 sulfidation-regeneration cycles were carried out using KRW-type coal gas with various zinc ferrite formulations. A number of sorbent manufacturing techniques including spray drying, impregnation, crushing and screening, and granulation were investigated. While fluidizable sorbents prepared by crushing durable pellets and screening had acceptable sulfur capacity, they underwent excessive attrition during multicycle testing. The sorbent formulations prepared by a proprietary technique were found to have excellent attrition resistance and acceptable chemical reactivity during multicycle testing. However, zinc ferrite was found to be limited to 550°C, beyond which excessive sorbent weakening due to chemical transformations, e.g., iron oxide reduction, was observed.

Book Synopsis Fluidized Bed Boilers by : Prabir Basu
Download or read book Fluidized Bed Boilers written by Prabir Basu and published by Elsevier. This book was released on 2013-10-22 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluidized Bed Boilers: Design and Application attempts to address the need for a single source of information covering all major areas of fluidized bed boiler design and operation. It is based on the International Workshop on Design and Operation of Atmospheric Pressure Fluidized Bed Boilers, organized by the Center for Energy Studies, Technical University of Nova Scotia in Halifax on 24-45 June 1983. The volume begins by presenting a simplified approach to the design of a fluidized bed boiler and an overview of problems in fluidized-bed combustion (FBC). These are followed by separate chapters on the equations and concepts needed to estimate key hydrodynamic parameters; the key factors and terms to be considered in selecting FBC for specific applications; and principles in the design of air distributors for a fluidized bed boiler. Subsequent chapters discuss heat transfer to surfaces in fluidized beds; the pollution control of fluidized bed combustion of solid fuels; and materials selection in atmospheric fluidized bed combustion systems. The final two chapters are devoted to applications. These include the operational and performance results of TVA’s 20-MW Atmospheric Fluidized Bed Combustion (AFBC) Pilot Plant in Kentucky; and the performance of Canada's first commercial FBC boiler plant, located at CFB Summerside, PEI.

Available in PDF, EPUB and Kindle. Book excerpt: The present disclosure is directed to a process that allows dry sorbents to remove a target constituent, such as carbon dioxide (CO.sub. 2), from a gas stream. A staged fluidized bed separator enables gas and sorbent to move in opposite directions. The sorbent is loaded with target constituent in the separator. It is then transferred to a regenerator where the target constituent is stripped. The temperature of the separator and regenerator are controlled. After it is removed from the regenerator, the sorbent is then transferred back to the separator.

This book was released on 1992 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this project are to identify and demonstrate methods for enhancing long-term chemical reactivity and attrition resistance of zinc ferrite and zinc titanate sorbents to be employed for desulfurization of hot coal-derived gases in a high-temperature, high-pressure (HTHP) fluid-bed reactor. The sorbent formulation specified for study during the base period of this project was zinc ferrite. Zinc titanate sorbents are being studied under two options to the base contract. Specific objectives of the zinc titanate sorbent development work are the following: The effect of following process variables was investigated o the performance of zinc titanate sorbents: Method of sorbent preparation, Composition of fuel gas, Zn to Ti ratio of the sorbent, Sulfidation temperature, and Superficial gas velocity. The effect of first three variables has been covered in RTI's 1991 paper (Gupta and Gangwal, 1991b), while the effect of temperature and superficial gas velocity is described here.
