HRSGs for Fast-Starting Combined Cycle Plants

HSRGs for Fast-Starting Combined Cycle Plants discusses key design specifications, operational issues, plant monitoring, and maintenance techniques for fast start HSRGs, including design changes in gas turbines, the operational demands of users, and a power environment that increasingly relies on flexible baseload as a supplement to intermittent renewables. Sections cover a description of combined cycle plant components, operational principles, and fast starting. In addition, the book reviews fast start impacts in key design and operating issues, ranging from mechanical integrity, operational control, HSRG component packaging, and effective emissions controls.

Finally, the book describes the necessary steps to gauge impacts on fast starts, suggesting solutions to eliminate or minimize the impact for an HRSG with a predictable optimum life, discussing design methodology for fast start HRSGs, instrumentation and control requirements, life consumption analysis, and balance of plant design management. Final sections consider key issues in the operation of fast-starting HRSGs, including operational control, operating protocols and strategy, monitoring programs, and predictive maintenance.
