In this paper, a new concept called “exergoeconoenvironmental” analysis is proposed for a better understanding of energy conversion systems with respect to thermodynamic, economic, and environmental perspectives simultaneously. The proposed methodology integrates exergy analysis, economic principles, and environmental assessment into a single framework to provide the decision-maker with information not accessible through available exergy-based methods like exergoeconomic and exergoenvironmental evaluations. In this methodology, the eco-costs/value ratio model is interfaced with exergetic cost theory in order to develop exergoeconoenvironmental balances for components of a given energy system. The systematic methodology used in exergoeconomic and exergoenvironmental analyses, i.e., Specific Exergy Costing, is employed to calculate the eco-costs/value for each stream of the system. The proposed methodology is applied to a well-known gas turbine-based cogeneration system consisting of an air compressor, an air preheater, a combustion chamber, a gas turbine, and a heat-recovery steam generator. The results obtained with the developed approach are compared with those of exergy, exergoeconomic, and exergoenvironmental analyses. The highest eco-costs/value ratio (3.806 USD eco-cost/USD value) is found for the heat-recovery steam generator, followed by the air preheater (2.919 USD eco-cost/USD value). Accordingly, these units are ranked first and second for improvement using exergoeconoenvironmental analysis. The exergoeconoenvironmental factor is small for all components of the plant, indicating the fact that the eco-costs/value ratio associated with exergy destruction is higher than the component-related eco-costs/value ratio. Accordingly, minimizing the exergy destruction can be recommended as a practical and sound strategy for improving the economoenvironmental performance of the plant. Overall, the proposed method appears to be a practical and powerful tool that assesses the efficiency, productivity, and sustainability of energy systems better than available exergy-based methods.

在本文中，提出了一个名为“能效环境经济”分析的新概念，以便同时从热力学，经济和环境的角度更好地理解能量转换系统。拟议的方法将火用分析，经济原理和环境评估整合到一个单一的框架中，为决策者提供通过火用经济和环境评估等基于火用的可用方法无法获得的信息。在这种方法中，生态成本/价值比模型与高能成本理论相联系，以便为给定能源系统的各个组成部分开发能环境与环境的平衡。能效经济和能效环境分析中使用的系统方法，即“特定能干成本”，用于计算系统每个流的生态成本/价值。所提出的方法应用于基于燃气轮机的热电联产系统，该系统由空气压缩机，空气预热器，燃烧室，燃气轮机和热回收蒸汽发生器组成。用开发的方法获得的结果与火用，能用经济和能用环境分析的结果进行了比较。热回收蒸汽发生器的生态成本/价值比最高（3.806美元生态成本/美元价值），其次是空气预热器（2.919美元生态成本/美元价值）。因此，使用exergoeconoenoviralmental分析，这些单元在改进方面分别排名第一和第二。植物的所有组成部分的exergoeconoenvironmental环境因子很小，表明与火用破坏相关的生态成本/价值比高于与零部件相关的生态成本/价值比。因此，可以建议将火用破坏最小化，作为提高植物生态环境性能的实用而合理的策略。总体而言，所提出的方法似乎是一种实用且功能强大的工具，它可以比现有的基于火用的方法更好地评估能源系统的效率，生产率和可持续性。
