HSRGs for Fast-Starting Combined Cycle Plants discusses key design specifications, operational issues, plant monitoring, and maintenance techniques for fast start HSRGs as they follow design changes in gas turbines and the operational demands of users, and in a power environment increasingly relying on flexible baseload as a supplement to intermittent renewables. Opening with a description of the combined cycle plant components and operational principles, the work provides a definition and description of fast starting, exploring the reasons for its necessity, and the relationship between it and cycling in the HRSG. It reviews fast start impacts in key design and operating issues, ranging through mechanical integrity, operational control, HSRG component packaging, and effective emissions controls. It describes in detail steps necessary 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. It closes by considering key issues in the operation of fast-starting HRSGs, including operational control, operating protocols and strategy, monitoring programs, and predictive maintenance Outlines key requirements for specifying HRSGs for Fast-Starting Combined Cycle PlantsDescribes salient features of the design process to understand the impact of fast starts on critical componentsExplains the importance of proper operation protocol to preclude the possibility of premature failure Evaluates on-line monitoring tools to gauge HRSG critical component life consumptionProvides detailed requirements for preparing effective specifications for HRSGs for fast-starting combined cycle plantsReviews design methodologies, analyses and guidelines for designing HRSGsDefines operation control protocols to avoid premature mechanical failures or performance deficiencies INDICE: PART A: SYSTEM DESCRIPTION AND REQUIREMENTS 1.
