Abstract The solar tower aided coal-fired power generation system (STCG) is based on a solar tower field and a conventional coal-fired power plant. Solar thermal energy is used to generate high-temperature and pressure steam to work in the coal-fired power plant. Indirect solar power generation and coal energy conservation goals can be achieved under

Advanced Exergetic Analysis of Chemical Processes
Volume 6: Emerging Technologies: Alternative Energy Systems; Energy Systems: Analysis, Thermodynamics and Sustainability, 2009In this paper, a steam methane reforming (SMR) process for the production of hydrogen is studied. The process is based on two chemical reactions (reforming and water-gas-shift reaction). For each component but especially focusing on the chemical reactors, the avoidable part of the exergy destruction is estimated.

An all-inclusive advanced exergy and exergoeconomic, analysis of a dry process, 5 million MTPA cement plant with real-time operational data located in Mfamosing, Cross River State, Nigeria was performed. The analysis was based on component-wise modelling by separating the exergy destruction (ED) rates into endogenous, exogenous, avoidable and ...

Sustainable Energy Technologies and Assessments, 2022
In this study, TOPSIS analysis was applied to decide the optimum refrigerants with cost, safety, environmental and enviroeconomic concerns along with thermophysical properties. A vapor compression refrigeration cycle performance was investigated with the statistical and thermodynamic approaches. COP, exergy efficiency, total, avoidable, and unavoidable

The irreversibilities (exergy destruction) within a component of an energy conversion system can be represented by two parts. The first part depends on the inefficiencies of the considered component while the second part depends on the system structure and the inefficiencies of the other components of the overall system.

CO 2 is the most environmentally friendly alternative for the upcoming future industry of refrigerants. However, low Coefficient of Performance (COP) values result from its need to work under transcritical conditions. This disadvantage is being overcome by different modifications to the classical refrigeration system.

Advanced Exergetic Analysis of a Double-Effect Series Flow Absorption Refrigeration System
Journal of Energy Resources Technology, 2020Abstract This paper contains theoretical results of an advanced exergy study of a double-effect series flow absorption refrigeration cycle. Traditional second law of thermodynamics analysis was performed and revealed the absorber as the component with the highest exergy destruction of the system.

CO2 capture and storage (CCS) is a way to minimize harmful emissions generated from the combustion of fossil fuels in power plants. Measures to increase the thermodynamic efficiency of power plants incorporating CCS can improve their economic viability, as well as reduce the environmental impact of such applications.

In the last decades an exergetic analysis became increasingly popular because this analysis identifies the location, magnitude and sources of thermodynamic inefficiencies. A conventional exergetic analysis, however, does not consider (a) the real potential for improving a system nor (b) the interactions among the components of the system.
