Multi-objective optimization of heat recovery steam generators
In this paper, a multi-objective method is used to optimize a heat recovery steam generator (HRSG). Two objective functions have been used in the optimization, which are irreversibility and HRSG equivalent volume. The former expresses the exergetic efficiency and the latter demonstrates the cost of the HRSG. Decision variables are geometric and operational parameters of the HRSG. The result...

متن کاملModeling and Cost Optimization of Combined Cycle Heat Recovery Generator Systems
The combined cycle power plant is made up of three major systems, the gas turbine engine, the heat recovery steam generator and the steam turbine. Of the major systems the gas turbine engine is a fixed design offered by a manufacturer, and the steam turbine is also a fairly standard design available from a manufacturer, but it may be somewhat customized for the project. In contrast, the heat re...
متن کاملتحلیل انرژی و اگزرژی کوپلینگ نیروگاه سیکل ترکیبی و آب‌شیرین‌کن تبخیری چندمرحله‌ای
Due to an increasing need of energy, lack of energy resources worldwide, it is very important to optimize energy generation plant to improve efficiency and production rate .One of the most important plant, for production of water and power are dual purpose power plants. In this kind of power plant a desalination system combines with power generation cycle. According to these issues, in this pap...
متن کاملexergetic optimization of designing parameters for heat recovery steam generators through direct search method
in this paper, first a sensitivity analysis of parameters affecting the performance of the steam generator is performed. this process includes the pinch temperature difference and the gas velocity (width of the hrsg) as the operating parameter and geometrical parameters (fin’s thickness, fin’s height, number of fins in each inch, tube transverse pitch) for each pressure parts is carried out, an...
