The book "The theory of furnace processes", written by outstanding specialists in the field of heat engineering and energy - G. F. Knorre, K. M. Arefiev, A. G. Bloh and others, edited by G. F. Knorr and E. and . Paleeva is a unique publication that will become an indispensable tool for students, graduate students and practicing engineers working in the field of design and operation of thermal installations. This is not just a textbook, but a whole encyclopedia of knowledge, covering a wide range of issues related to heating processes. The book immerses the reader in the world of thermodynamics and heat transfer, revealing the basic principles underlying the operation of various types of boilers and furnaces. The authors carefully analyzed and systematized information about combustion processes, heat exchange and flow dynamics, which allows the reader to understand more deeply how furnace systems function. Particular attention is paid to modern methods of calculation and modeling, which makes the book relevant for specialists seeking to apply the latest technologies in their practice. Who is this book intended for? First of all, it will be of interest to students of technical universities studying thermal energy and related disciplines. It will also be useful for graduate students and young scientists who want to deepen their knowledge in the field of furnace processes. Practicing engineers and energy professionals will find in it a lot of useful information that will help in solving specific production tasks. The book will also be useful for those who are interested in modern technologies in the field of energy and ecology, as it deals with aspects related to environmental safety and energy efficiency. Topics raised in the "Theory of furnace processes" cover not only theoretical aspects, but also practical recommendations for optimizing the operation of thermal installations. The authors emphasize the importance of fuel selection, combustion characteristics and process control methods, which allows to significantly increase the efficiency of boilers and reduce their negative impact on the environment. This book will be an important contribution to the development of sustainable energy, which makes it especially relevant in the face of modern environmental challenges. The style of the authors is distinguished by the clarity and accessibility of the presentation, which allows even complex scientific concepts to be presented in an understandable and visual form. G. F. Knorre, as one of the leading experts in the field of thermal power engineering, is already known for his work, such as “Heat engineering” and “Heat processes in power plants”. His experience and knowledge, as well as the contributions of other authors, make this book a valuable source of information. If you are looking for literature on topics related to heat engineering, combustion, heat exchange or the design of energy systems, then the "Fuel Process Theory" will be a real find for you. It will not only expand your knowledge, but also inspire new ideas and solutions in the field of energy. Do not miss the opportunity to get acquainted with this outstanding work, which combines theory and practice, and discover new horizons in the world of furnace processes!
