The book "Control and diagnostics of thermal and mechanical equipment of thermal power plants" by the authors Gerasimov A. G. and Kachan S. A. is an indispensable work for all who are interested in modern technologies in the field of energy, as well as for specialists working in the field of thermal power plants In this publication, the authors detail the key aspects of control and diagnostics, which makes it relevant for both students of technical universities and practicing engineers. From the first pages, the reader is immersed in the world of complex systems that ensure the operation of heat-mechanical equipment. The book begins with the basics, explaining the principles of operation of thermal power plants and their components. However, as in any complex system, there are many issues related to the efficiency and reliability of the equipment. It is these questions that this publication answers, offering the reader not only theoretical knowledge, but also practical recommendations. One of the main topics of the book is diagnostics .. The authors consider in detail the methods and technologies used to identify malfunctions and assess the condition of equipment. The reader will learn about modern approaches to diagnostics, such as vibration analysis, thermography and ultrasound diagnostics. These methods allow not only to identify current problems, but also to predict possible malfunctions, which is especially important for ensuring the smooth operation of thermal power plants. The book will be of particular interest to students and graduate students studying thermal power engineering, as well as engineers and technicians working at TPP. It will become a useful guide for those who want to deepen their knowledge in the field of control and diagnostics, as well as for all who seek to improve the efficiency and safety of heat-mechanical equipment. The topics raised in the book go beyond a simple description of technology. The authors emphasize the importance of a systematic approach to diagnosis, emphasizing that every detail in the system matters. They discuss not only technical aspects, but also organizational issues related to the implementation of control systems in enterprises. This makes the book especially valuable for executives and managers who seek to optimize processes in their businesses. The style of the authors is distinguished by clarity and accessibility, which makes it easy to assimilate even the most complex concepts. Gerasimov and Kachan use many examples from practice, which makes the material more visual and understandable. Their expertise in thermal power engineering and diagnostics allows them to share valuable insights and recommendations that can be useful to both beginners and experienced professionals. If you are looking for books on similar topics, pay attention to the works of authors such as Kuznetsov and Petrov, who also deal with issues of diagnostics and control in the field of energy.
