The book "Reliability of the operation of the on-screen pipes of the steam generator with natural circulation under non-stationary modes" by Katkovskaya K. This is a unique study that immerses the reader in the complex world of heat engineering and energy. In this work, the author analyzes in detail the operation of on-screen pipes of steam generators, which play a key role in modern heat supply systems and power plants. The book is not only a scientific guide, but also a practical guide for engineers, students and anyone interested in the reliability and efficiency of thermal processes. The focus of Katkovskaya is the problem of non-stationary modes of steam generators. These modes can occur as a result of various factors, such as changes in load, fluctuations in temperature and pressure, and external influences. The author examines in detail how these factors affect the reliability of screen pipes, and suggests methods for their assessment and improvement. The reader will be able to learn about modern approaches to the diagnosis and prediction of the condition of pipes, which is especially important for specialists in the field of energy and heat engineering. The book will be of interest not only to professional engineers and researchers, but also to students of technical universities who study thermal engineering and energy engineering. It is suitable for those who seek to understand more deeply the mechanisms of steam generators and want to gain practical skills in assessing their reliability. This work can also attract the attention of scientists engaged in the development of new technologies and methods in the field of energy. The topics raised in the book go beyond purely technical issues. Katkovskaya touches on important aspects of sustainable development and ecology, discussing how reliable operation of steam generators can contribute to reducing the negative impact on the environment In the context of global climate change and the need to switch to cleaner energy sources, such studies are becoming especially relevant. The book highlights the importance of reliability and efficiency of energy systems to ensure a sustainable future. Katkovskaya’s style is distinguished by clarity and logical presentation, which makes complex technical aspects accessible for understanding. It uses many examples and illustrations, which allows the reader to better absorb the material and apply it in practice. Katkovskaya is also known for her other work in the field of heat engineering, where she explores various aspects of the operation of power plants and heat supply systems. Her approach to scientific research always differs in depth of analysis and practical focus. If you are looking for a book that combines theory and practice, as well as current research in the field of energy, "Reliability of the on-screen steam generator pipes with natural circulation under non-stationary modes" will be an excellent choice. This work will not only expand your knowledge about steam generators, but also help you better understand how to ensure their reliable and efficient operation in modern conditions. Read, explore and discover new horizons in the world of heat engineering together with Katkovskaya!
