Coal Power Plant Materials and Life Assessment: Developments and Applications

Due to their continuing role in electricity generation, it is important that coal power plants operate as efficiently and cleanly as possible. Coal Power Plant Materials and Life Assessment reviews the materials used in coal plants, and how they can be assessed and managed to optimize plant operation. Part I considers the structural alloys used in coal plants. Part II then reviews performance modelling and life assessment techniques, explains the inspection and life-management approaches that can be adopted to optimize long term plant operation, and considers the technical and economic issues involved in meeting variable energy demands.

Summarizes key research on coal-fired power plant materials, their behavior under operational loads, and approaches to life assessment and defect managementDetails the range of structural alloys used in coal power plants, and the life assessment techniques applicable to defect-free components under operational loadsReviews the life assessment techniques applicable to components containing defects and the approaches that can be adopted to optimize plant operation and new plant and component design
