Book excerpt: This open access book surveys the development of OCAC technology in the last decade for solid fuel conversion in fluidized beds. The scientific concerns, including combustion and emission characteristics, ash-related problems, OC aging, and so on, are summarized and analyzed. Beyond this, new concepts like OCAC with Oxy-PFBC, OCAC coupled with staged fuel conversion, OCAC in rotatory kilns and multi-functional OCAC are proposed, so as to promote the applications of OCAC to various fields in the future. Moreover, this book also outlines the perspectives for future research and development of OCAC. As an emerging technology, extensive studies and investigations are still necessary to fill in the gap from the fundamental understanding of the technology to its industrial demonstrations. Nevertheless, we believe that this book provides novel insights for the readership of energy and combustion and stimulate meaningful follow-on research on OCAC technology.

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

Book excerpt: Chemical Looping Combustion is a novel combustion technology for the inherent separation of the greenhouse gas, CO2. In 1983, Richter and Knoche proposed reversible combustion, which utilized both the oxidation and reduction of metal. Metal associated with its oxidized form as an oxygen carrier was circulated between two reactors--oxidizer and reducer. In the reducer, the solid oxygen carrier reacts with the fuel to produce CO2, H2O and elemental metal only. Pure CO2 will be obtained in the exit gas stream from the reducer after H2O is condensed. The pure CO2 is ready for subsequent sequestration. In the oxidizer, the elemental metal reacts with air to form metal oxide and separate oxygen from nitrogen. Only nitrogen and some unused oxygen are emitted from the oxidizer. The advantage of CLC compared to normal combustion is that CO2 is not diluted with nitrogen but obtained in a relatively pure form without any energy needed for separation. In addition to the energy-free purification of CO2, the CLC process also provides two other benefits. First, NO(subscript x) formation can be largely eliminated. Secondly, the thermal efficiency of a CLC system is very high. Presently, the CLC process has only been used with natural gas. An oxygen carrier based on an energy balance analysis and thermodynamics analysis was selected. Copper (Cu) seems to be the best choice for the CLC system for solid fuels. From this project, the mechanisms of CuO reduction by solid fuels may be as follows: (1) If pyrolysis products of solid fuels are available, reduction of CuO could start at about 400 C or less. (2) If pyrolysis products of solid fuels are unavailable and the reduction temperature is lower, reduction of CuO could occur at an onset temperature of about 500 C, char gasification reactivity in CO2 was lower at lower temperatures. (3) If pyrolysis products of solid fuels are unavailable and the reduction temperature is higher than 750 C, all reaction reactivities were improved, especially the CO2 gasification reactivity of char. Thus, the reduction of CuO by the gasification product CO could proceed quickly. Based on the results obtained, the following coal characteristics would be desirable for the Chemical Looping Combustion process: high volatile matter with a high reactivity of the char produced. PRB coal meets these criteria while being comparatively less expensive and also very abundant. The high moisture content present in PRB coal might also increase the reactivity for char gasification through the development of pore structure and specific surface area in the char during pyrolysis. Biomass materials are also suitable, considering the reaction mechanism of CLC system of solid fuels. The feasibility of the chemical looping combustion process of solid fuels was verified by focusing on PRB coal and biomass. Based on PRB coal as the preferred solid fuel in the development of the CLC system, the mass, energy and system in a dual reactor recirculation system has been determined. In the Cu oxidation tests, it was confirmed that the heating rate is the most important effect on the Cu oxidation process. Lower heating rates and lower operational temperatures would result in incomplete conversion of Cu to CuO. Cu2O may be the intermediate product. The operating temperature did not affect the reaction rate of the oxidation process. Under any operating conditions, the exothermic properties are clearly shown.

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: Besides being one of the best Clean Coal Technologies, fluidized beds are also proving to be the most practical option for biomass conversion. Although the technology is well established, the field lacks a comprehensive guide to the design and operating principles of fluidized bed boilers and gasifiers. With more than 30 years of research and industrial experience, Prabir Basu answers this pressing need with Combustion and Gasification in Fluidized Beds. This book is a versatile resource that explains how fluidized bed equipment works and how to use the basic principles of thermodynamics and fluid mechanics in design while providing insight into planning new projects, troubleshooting existing equipment, and appreciating the capabilities and limitations of the process. From hydrodynamics to construction and maintenance, the author covers all of the essential information needed to understand, design, operate, and maintain a complete fluidized bed system. It is a must for clean coal technology as well as for biomass power generation. Beginning with a general introduction to fossil or biofuel conversion choices, the book surveys hydrodynamics, fundamentals of gasification, combustion of solid fuels, pollution aspects including climate change mitigation, heat transfer in fluidized beds, the design and operation of bubbling and circulating fluidized bed boilers, and various supporting components such as distributor grates, feeding systems, and gas-solid separators.
