This textbook comprehensively covers the fundamental aspects of combustion. It includes physical descriptions of premixed and non-premixed flames. It provides a detailed analysis of the basic ideas and design characteristics of burners for gaseous, liquid and solid fuels. A chapter on alternative renewable fuels has also been included to bring out the need, characteristics and usage of alternative fuels. Review questions have been provided at the end of each chapter which will help the students to evaluate their understanding of the important concepts covered in that chapter. Several standard text books have been cited in the chapters and are listed towards the end, as suggested reading, to enable the readers to refer them when required. The textbook will be useful for students in mechanical, aerospace and related fields of engineering. It will also be a good resource for professionals and researchers working in the areas of combustion technology.

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.

Combustion Technology: Some Modern Developments reviews modern developments in combustion technology, with emphasis on furnace flames. Topics covered range from equilibria and chemical kinetics in flames to corrosion and deposits in combustion systems, along with combustion aerodynamics and noise. Heat transfer from non-luminous flames in furnaces is also investigated. Comprised of 15 chapters, this book begins with an overview of some aspects of the chemistry of flames, followed by a discussion on the problem of corrosion and deposits. Subsequent chapters focus on aerodynamics and heat transfer in combustors, together with combustion noise and the application of aerodynamic principles to flame stabilization in high-speed flow; radiative heat transfer in combustion chambers; electrical properties of flames; flame-field interactions and their practical applications; generation of electricity by magnetohydrodynamic methods; and practical aspects of magnetohydrodynamic power generation. The book also assesses the influence of stirred reactor theory on design principles for high-performance combustion chambers and concludes with a summary of developments in the design and utilization of oil burners. This monograph should be of interest to engineers and combustion technologists.

Fundamentals and Technology of Combustion contains brief descriptions of combustion fundamental processes, followed by an extensive survey of the combustion research technology. It also includes mathematical combustion modeling of the processes covering mainly premixed and diffusion flames, where many chemical and physical processes compete in complex ways, for both laminar and turbulent flows. The combustion chemistry models that validate experimental data for different fuels are sufficiently accurate to allow confident predictions of the flame characteristics. This illustrates a unique bridge between combustion fundamentals and combustion technology, which provides a valuable technical reference for many engineers and scientists. Moreover, the book gives the reader sufficient background of basic engineering sciences such as chemistry, thermodynamics, heat transfer and fluid mechanics. The combustion research and mathematical models fit between small-scale laboratory burner flames, and large-scale industrial boilers, furnaces and combustion chambers. The materials have been collected from previous relevant research and some selected papers of the authors and co-workers, which have been presented mainly in different refereed journals, international conferences and symposia, thus providing a comprehensive collection. Furthermore, the book includes some of the many recent general correlations for the characteristics of laminar, turbulent, premixed and diffusion flames in an easily usable form. The authors believe that further progress in optimizing combustion performance and reducing polluting emissions can only be treated through understanding of combustion chemistry.

Biomass-fired steam boilers are finding increasing use in industrial-scale applications for both heat and power generation. This chapter compares the main technologies for biomass combustion – spreader stoker, mass burn and biomass bubbling fluidised bed (BFB)/circulating fluidised bed (CFB) – and discusses specific issues to be addressed in the design of biomass-fired steam boiler plants. Examples of recent biomass-to-energy plants are given in order to illustrate how project-specific factors influenced the design. A section is dedicated to non-wood biomass fuels and how their characteristics affect plant design. Conversion of existing coal-fired boilers to biomass firing is also discussed. The final part of the chapter deals with operational issues of biomass-fired plants.
