Features: This book comprehensively and systematically elaborates on the comprehensive impact of flue gas desulfurization (FGD) systems on power generation units in China, including the effects of FGD system operation on boiler operation, steam turbine operation, the impact on the boiler's tail flue and chimney, and the effects of mixed discharge of gypsum slurry and ash-water on the ash and slag discharge system of the unit. The authors conduct a detailed analysis of the corrosive environment within wet FGD systems and corrosion prevention measures, propose the concept of the corrosivity index Ks for FGD systems, and introduce the safety concept of FGD systems, which encompasses the impact on the safety of power generation units and the safety of the FGD system itself. Based on practical operational experience with FGD systems, the book elaborates on the meaning in detail. It also proposes the concept of FGD system optimization and provides an in-depth discussion, covering three aspects: the optimal selection of FGD system processes, the design and operational optimization of the selected FGD system, and the localization of FGD systems. The book also introduces China's current SO? emission status and control history, as well as the latest FGD technologies in domestic and international thermal power plants, as well as the commissioning and operational technologies of FGD systems. The content of the book is rich, novel, and well-illustrated, closely linked to engineering practice, and provides valuable reference for various aspects of FGD system design, equipment selection, operation, and commissioning. This book can serve as a reference for researchers, designers, commissioning engineers, testers, operators, and managers engaged in flue gas desulfurization technology in thermal power plants, as well as a teaching reference for postgraduate and undergraduate students in relevant fields at universities.
