HEAT TRANSFER IN INDUSTRIAL COMBUSTION

HEAT TRANSFER IN INDUSTRIAL COMBUSTION

 

This book is intended to fill a gap in the literature for books on heat transfer in industrial combustion,

written primarily for the practicing engineer. Many textbooks have been written on both heat transfer

and combustion, but both types of book generally have only a limited amount of information concerning the combination of heat transfer and industrial combustion. One of the purposes of this book is to codify the many relevant books, papers, and reports that have been written on this subject into a single, coherent reference source.

The key difference for this book compared to others is that it looks at each topic from a somewhat narrow scope to see how that topic affects heat transfer in industrial combustion. For example, in Chapter 2, the basics of combustion are considered, but from the limited perspective as to how combustion influences the heat transfer. There is very little discussion of combustion kinetics because in the overall combustion system, the kinetics of the chemical reactions in the flame only significantly impact the heat transfer in somewhat limited circumstances. Therefore, this book does not attempt to go over subjects that have been more than adequately covered in other books, but rather attempts to look at those subjects through the narrow lens of how they influence the heat transfer in the system.

The book is basically organized in three parts. The first part deals with the basics of heat transfer in combustion and includes chapters on the modes of heat transfer, computer modeling, and experimental techniques. The middle part of the book deals with general concepts of heat transfer in industrial combustion systems and includes chapters on heat transfer from flame impingement, from burners, and in furnaces. The last part of the book deals with specific applications of heat transfer in industrial combustion and includes chapters on lower and higher temperature applications and some advanced applications. The book has discussions on the use of oxygen to enhance combustion and on flame impingement, both of particular interest to the author. These subjects have received very little, if any, coverage in previous books on heat transfer in industrial combustion.

As with any book of this type, there are many topics that are not covered. The book does not address other aspects of heat transfer in combustion such as power generation (stationary turbines or boilers) and propulsion (internal combustion, gas turbine or rocket engines), which are not normally considered to be industrial applications. It also does not treat packed bed combustion, material synthesis in flames, or flare applications, which are all fairly narrow in scope. Because the vast majority of industrial applications use gaseous fuels, that is the focus of this book, with only a cursory discussion of solid and liquid fuels. This book basically concerns atmospheric combustion, which is the predominant type used in industry. There are also many topics that are discussed in the book, but with a very limited treatment. One example is optical diagnostics. The reason for the limited discussion is that there has been very little application of such techniques to industrial combustors because of the difficulties in making them work on a large scale in sometimes hostile environments.

This book attempts to focus on those topics that are of interest to the practicing engineer. It does not profess to be exhaustively comprehensive, but does attempt to provide references for the interested reader who would like more information on a particular subject. As most authors know, it is always a struggle about what to include and what not to include in a book. Here, the guideline that has been used is to minimize the theory and maximize the applications, while at the same time trying to at least touch on the relevant topics for heat transfer in industrial combustion.
