Calculations in Furnace Technology presents the theoretical and practical aspects of furnace technology. This book provides information pertinent to the development, application, and efficiency of furnace technology. Organized into eight chapters, this book begins with an overview of the exothermic reactions that occur when carbon, hydrogen, and sulfur are burned to release the energy available in the fuel. This text then evaluates the efficiencies to measure the quantity of fuel used, of flue gases leaving the plant, of air entering, and the heat lost to the surroundings. Other chapters consider that it is important to determine the amount of carbon discharged with the ashes, the quantity and composition of any tar produced, so that a carbon balance can be applied. The final chapter describes the various reactions within the furnace atmosphere and between charges and atmosphere. This book is a valuable resource for fuel technologists, heating and ventilating engineers, and plant operators.

Numerical Prediction of Flow, Heat Transfer, Turbulence and Combustion: Selected Works of Professor D. Brian Spalding focuses on the many contributions of Professor Spalding on thermodynamics. This compilation of his works is done to honor the professor on the occasion of his 60th birthday. Relatively, the works contained in this book are selected to highlight the genius of Professor Spalding in this field of interest. The book presents various research on combustion, heat transfer, turbulence, and flows. His thinking on separated flows paved the way for the multi-dimensional modeling of turbulence. Arguments on the universality of the models of turbulence and the problems that are associated with combustion engineering are clarified. The text notes the importance of combustion science as well as the problems associated with it. Mathematical computations are also presented in determining turbulent flows in different environments, including on curved pipes, curved ducts, and rotating ducts. These calculations are presented to further strengthen the claims of Professor Spalding in this discipline. The book is a great find for those who are interested in studying thermodynamics.

This introduction to heat transfer offers advanced undergraduate and graduate engineering students a solid foundation in the subjects of conduction, convection, radiation, and phase-change, in addition to the related topic of mass transfer. A staple of engineering courses around the world for more than three decades, it has been revised and updated regularly by the authors, a pair of recognized experts in the field. The text addresses the implications, limitations, and meanings of many aspects of heat transfer, connecting the subject to its real-world applications and developing students' insight into related phenomena. Three introductory chapters form a minicourse in heat transfer, covering all of the subjects discussed in detail in subsequent chapters. This unique and effective feature introduces heat exchangers early in the development, rather than at the end. The authors also present a novel and simplified method for dimensional analysis, and they capitalize on the similarity of natural convection and film condensation to develop these two topics in a parallel manner. Worked examples and end-of-chapter exercises appear throughout the book, along with well-drawn, illuminating figures.

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.
