Thermal Power Plant Control and Instrumentation: The control of boilers and HRSGs, 2nd edition

Thermal Power Plant Control and Instrumentation describes the systems and equipment used for measuring and controlling boilers and heat-recovery steam-generators used in land and marine power plant and in process industries. It provides a practical guide to the design, installation, operation and maintenance of these systems. Starting with descriptions of how each area of the plant operates, it shows how the relevant control systems have evolved, how they are implemented in modern systems and how to evaluate the merits of alternative approaches. The rise of renewable power in the generation mix, and of biomass in the fuel, has demanded greater flexibility from combustion plants, requiring more sophisticated and robust control. In parallel, thermal power plants have been developed with overfire air systems to reduce NOx, once-through supercritical boilers to increase efficiency and model-based control schemes to optimise response. These developments have brought opportunities in terms of flexibility, energy efficiency and safety, but also the risk of a comprehension gap between control specialists and power plant engineers, a gap this new edition aims to bridge. The rise of renewable power generation using wind and solar energy has created the challenge of greater flexibility for combustion plants, requiring more sophisticated and robust control. Developments in control technology have brought opportunities for the power industry in terms of flexibility, energy efficiency and safety, but also the risk of a comprehension gap between control specialists and power plant engineers. This practically-oriented book bridges the gap. Contents include a wide variety of plant and combustion arrangements, from smaller boiler systems to full-scale generators, common principles, commercial aspects, measurement, and key techniques such as cogeneration and combined cycle Chapter 1: The basics of steam generation and use Chapter 2: The steam and water circuits Chapter 3: The fuel, air and flue-gas circuits Chapter 4: Setting the demand for the steam generator Chapter 5: Combustion and draught control Chapter 6: Feedwater control and instrumentation Chapter 7: Steam temperature control and measurement Chapter 8: Control equipment practice Chapter 9: Requirements definition and equipment nomenclature Chapter 10: Functional safety and associated reviews for boiler protection and control systems Chapter 11: Improving plant automation and operational flexibility Chapter 12: Upgrading and refurbishing systems The primary objective of this book is the plant design right down to control and instrumentation systems. As a result, the control engineer is faced with handling new plant concepts such as Lo-NOx burners and carbon-capture and recycling. As ever, the control system designer has to have a good understanding of the plant and its method of operation before he or she can produce an effective design. Aiding that understanding is the primary objective of this book. Control technology itself changes and changes again over time: the principles of thermodynamics don't This book describes the systems and equipment used for measuring and controlling boilers and heat-recovery steam-generators used in land and marine power plant and in process industries.
