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 Plants Describes salient features of the design process to understand the impact of fast starts on critical components Explains the importance of proper operation protocol to preclude the possibility of premature failure Evaluates on-line monitoring tools to gauge HRSG critical component life consumption Provides detailed requirements for preparing effective specifications for HRSGs for fast-starting combined cycle plants Reviews design methodologies, analyses and guidelines for designing HRSGs Defines operation control protocols to avoid premature mechanical failures or performance deficiencies

Highlights: Dynamic simulation model of 350MWth supplementary-fired combined-cycle power is developed. All process, automation and electrical components of the real power plant are modelled. Dynamic simulations of switching off the supplementary firing, part loads and start-ups are carried out. GT start-up time reductions by 30%, 80% and 93% in hot, warm and cold start-ups is achieved. HRSG reaches faster its nominal power output by 38%, 31% and 20% in hot, warm and cold start-ups. Abstract: The start-up time of a combined-cycle power plant depends mainly on the heat recovery steam generator (HRSG) with its thick-walled tubes. This work contributes to a start-up time reduction of a large combined-cycle power plant (CCPP) with a supplementary-fired HRSG. Hence, a dynamic simulation model is developed using the advanced process simulation software (APROS). The flue gas path and the water/steam side are modelled in detail. All control structures required for the plant operation are implemented, e.g. drum, steam turbine bypass system and steam temperature control. The comparison between model predictions and design data at different load changes shows high correlation towards given data with an average relative error of 5%. Using the developed model, hot, warm and cold start-ups are simulated and finally three different reduced start-up times of gas turbine (15min, 24min and 38min) are evaluated. A comparison between baseline and improved start-ups reveals time saving and fast power generation rate.

Desalination Update illustrates the growing research and development activities in the field of desalination of water. The chapters in this book also show the close link in the supply of water and supply of power. Power is needed to desalinate water, and water is needed to produce power via steam and cooling water. As the world is becoming increasingly in need of water and power, the education of generations of new workers in these technologies makes the publications of these books of rising importance. Students and specialists alike will find branching strands in this field of development worthy of dedication of careers. Never has shrinking essential resources and exploding needs confront mankind as much as water. Excellent reviews in this book provide keywords, concepts, and current knowledge and status of practice useful for teaching and continued evolution.

The book provides highly specialized researchers and practitioners with a major contribution to mathematical models’ developments for energy systems. First, dynamic process simulation models based on mixture flow and two-fluid models are developed for combined-cycle power plants, pulverised coal-fired power plants, concentrated solar power plant and municipal waste incineration. Operation data, obtained from different power stations, are used to investigate the capability of dynamic models to predict the behaviour of real processes and to analyse the influence of modeling assumptions on simulation results. Then, a computational fluid dynamics (CFD) simulation programme, so-called DEMEST, is developed. Here, the fluid-solid, particle-particle and particle-wall interactions are modeled by tracking all individual particles. To this purpose, the deterministic Euler-Lagrange/Discrete Element Method (DEM) is applied and further improved. An emphasis is given to the determination of inter-phase values, such as volumetric void fraction, momentum and heat transfers, using a new procedure known as the offset-method and to the particle-grid method allowing the refinement of the grid resolution independently from particle size. Model validation is described in detail. Moreover, thermochemical reaction models for solid fuel combustion are developed based on quasi-single-phase, two-fluid and Euler-Lagrange/MP-PIC models. Measurements obtained from actual power plants are used for validation and comparison of the developed numerical models.
