This book serves as a practical and authoritative guide on boiler operation engineering. Designed in a unique question-and-answer format, it provides professionals in the fields of boiler operation, design, supervision, inspection, and maintenance with immediate solutions to real-world challenges. With updated industry data and real-life examples, the content offers in-depth coverage of the design and upgrade processes for boilers and their components. Boiler Operation Engineering, 4e is split into two volumes-BOE-1 and BOE-2. Volume 2 delves into advanced topics in boiler operation and steam generation systems, including cooling tower design, water treatment processes, fouling and corrosion prevention, and turbine technologies. It covers the complexities of steam and gas turbines, heat recovery steam generators (HRSG), and boiler design, including revamping old coal-fired units with CFB boiler units. It also discusses the upfront technology like hydrogen-burning boilers, while delving deeper into the latest developments in nuclear and waste-to-energy power generation. BOE-2 also explores NDE and condition monitoring techniques, and boiler failure analysis, with a particular focus on ensuring the long-term efficiency and reliability of steam generation plants. With detailed case studies and practical solutions, this volume is essential for professionals looking to optimize plant operations and extend the lifespan of critical equipment. The book will prove useful to professional engineers as well as researchers. Its unique format also makes it useful as a supplementary text for students of mechanical, industrial, chemical, and power plant engineering disciplines.
