Thermoeconomic analysis of multi-stage recuperative Brayton power cycles: Part I- hybridization with a solar power tower system February Energy Conversion and Management. The rising of the global energy demand requires the use of alternative energy conversion systems employing renewable sources. In the refrigeration and air conditioning fields, heat driven ejector systems represent a promising way to produce the cooling effect by using available low-grade temperature sources. In this paper, a thermo-economic analysis of a waste heat recovery hybrid ejector Author: Gianluca Lillo, Rita Mastrullo, Alfonso William Mauro, Raniero Trinchieri, Luca Viscito.

That is, the number of the proposed equation is only one in each ﬁeld, and it is developed with a . Abstract. The chapter presents the application of thermoeconomics to the analysis of a sample biomass energy conversion system. Thermoeconomics is aimed at the analysis, optimization and diagnosis of energy conversion systems; it is based on the concept of exergy which is constantly gaining more popularity among engineers and researchers, and the concept of by: 3.
A small-scale solar organic Rankine cycle (ORC) is a promising renewable energy-driven power generation technology that can be used in the rural areas of developing countries. A prototype was developed and tested for its performance characteristics under a range of solar source temperatures. The solar ORC system power output was calculated based on the thermal and solar collector by: In this Article, a systematic approach of cost analysis and optimization for combining the multieffect thermal vapor compression (METVC) desalination system with the gas turbine power plant (GT) was proposed on the basis of thermodynamic, economic, and environmental attributes. The total annual cost (TAC) of the combined system, including annual capital and operating costs, was Cited by:

Means of applying optimization techniques for large scale systems to the thermoeconomic analysis of environmental vapor power systems are described and demonstrated with a simplified sample model. A sequential unconstrained minimization algorithm is employed for overall system design optimization.
Thermoeconomic analysis of environmental vapor power systems. By Furman Ladow Sheppard Get PDF (5 MB)Author: Furman Ladow Sheppard. Reza et al. proposed a multigeneration energy system, which involved a coal and biomass co-gasification process, a cryogenic air separation unit based on the LNG vaporization, a steam cycle, a supercritical CO 2 power cycle, and a cryogenic carbon dioxide capture system.
The LNG cold energy was used in each process, and the overall system exergy efficiency was reported as 97%. Environmental evaluation of system. Except for the economic analysis, the environmental imprint has a significant impact on refrigerant assessment.
The use of the total equivalent warming impact (TEWI) is an index aiming at estimating the total contribution to global warming and details about the calculation can be found in many : Zhenhong Ye, Jingye Yang, Junye Shi, Jiangping Chen.
The main objective of the thermoeconomic diagnosis is to detect possible anomalies and their location inside a component of the energy system. The second objective, and indeed the one to be achieved in this paper, is indicated as inverse problem.
Pardal et al  did a study of thermoeconomic analysis which can be incorporated into refrigeration or an air conditioning system. Kalla and Usmani  reported the comparative performance. The role of energy and exergy analysis for defining the cost and benefits in refrigeration systems was shown with the thermo-economic analysis that is based on the second law of thermodynamics.
The optimum conditions for thermodynamic and economic performance of the system are achieved by considering the economic and thermodynamic parameters simultaneously (Yang et al., ).Cited by: The current study is focused on thermoeconomic analysis of a single effect mechanical vapor compression (MVC) desalination system operating with and without brine recirculation.

Exergy and Thermoeconomic Analyses for Thermal Systems.
A general exergy balance equation  and the corresponding cost-balance equation  that are applicable to any component of thermal systems have been formulated.
The exergy of material stream involved in the component of any thermal system was decomposed into thermal, mechanical and chemical exergy flows and an entropy. This study presents a thermoeconomic analysis methodology to calculate unit energy (electricity and heat) production cost for a combined cycle system with steam extraction (cogeneration system).
Abstract. The exergy and thermoeconomic analysis of components of power plants, refrigeration and polygeneration systems is presented and discussed to characterize the performance of such systems as well as to determine their products cost formation processes.

In this work, the thermoeconomic analysis is performed to assess the performance of a single effect-mechanical vapor compression desalination unit. Thermoeconomic equations based on Specific Exergy Costing (SPECO) method are developed for the analysis.
A conventional vapor-compression desalting system is analyzed thermodynamically and economically by the concepts of essergy and internal economy. Thermodynamic analysis using the concept of essergy reveals that the low thermodynamic efficiency is inherent to the process even when the pieces of equipment have individual high thermodynamic Cited by: A new combined supercritical CO2 recompression Brayton/Kalina cycle (SCRB/KC) is proposed.
