The fifth edition of Combustion is similar in format to the fourth edition. However, there are new sections and additions, and many brief insertions that are the core of important modifications. New to this edition are sections on the combustion kinetics and low-temperature chemistry of biofuels, catalytic combustion, the combustion of nanomaterials, chemical looping, and the mixture fraction concept. Updated appendices and additional problems are at the end of chapters. In addition, small, important modifications have been inserted throughout the text to give greater understanding to many elements of combustion. This new material and other major additions are self-evident in the listings in the Table of Contents.

As with the fourth edition of Combustion, special thanks go to Dr. Chris Shaddix of Sandia Livermore, who made major contributions to Chapter 9 with respect to coal combustion considerations. Our thanks go to Mary Newby of Penn State, who performed the typing of the complete book and who with insight offered a great deal of general help. We also wish to thank our Acquisitions Editor, Tiffany Gasbarrini, and Senior Editorial Project Manager, Kattie Washington, for convincing us to undertake this edition of Combustion and for seeing this endeavor through.
