Recent developments in exergy analysis and exergoeconomics

International Journal of Exergy, 2008
In advanced exergy analysis, the exergy destruction within a component of an energy conversion system can be split into avoidable/unavoidable exergy destruction and endogenous/exogenous exergy destruction. A combination of these two concepts provides accurate information with respect to improving the overall system efficiency.

Application of exergoeconomics to the analysis and optimization of process systems

Journal of Thermal Science, 1996
The definitions and purposes of energy systems and process systems are compared in this paper by considering the role of energy in systems with emphasis on the differences in the methods used to optimize the exergoeconomic benefits of both types of systems.

Analysis of Some Exergoeconomic Parameters of Small Wind Turbine System

International Journal of Green Energy, 2009
This paper investigates some exergoeconomic parameters (energy and exergy loss ratios) for a 1.5 kW wind turbine system, linking capital costs and thermodynamic losses, based on some operating conditions. The results show that while the ratio of energy loss rate to capital cost (Ren) changes between 0.007 and 0.813 at different wind speeds, the ratio ...

Exergoeconomic Analysis of an Advanced Zero Emission Plant

Volume 6: Emerging Technologies: Alternative Energy Systems; Energy Systems: Analysis, Thermodynamics and Sustainability, 2009
Exergy-based methods are reliable means for the comparison and the evaluation of the operation of energy conversion systems. In this paper, the Advanced Zero Emission Plant, a plant that performs combustion in a nitrogen-free environment (oxy-fuel combustion) is presented, compared to a reference plant (without CO2 capture) and evaluated based on an ...

Exergoeconomic methodology for analysis and optimization of process systems

Computers & Chemical Engineering, 2000
Abstract This paper describes the progress of a systematic exergoeconomic methodology for analysis and optimization of process systems. Based on the three-link-model, by applying a reversed exergy costing method to process systems, a hierarchical exergoeconomic model is developed and the decomposing-coordinating optimization strategy is introduced to

Exergoeconomic Analysis of a Steam Power Plant in Iran

Applied Mechanics and Materials, 2011
The exergy and exergoeconomic of the Qazvin steam power plant carried out here. In this paper the exergy destruction and efficiency of each component of this power plant is estimated. Since in every power plant there are different working loads and ambient temperature is varying during seasons, the effect of the load variations and the ambient ...
