用资源的观点评价能源利用项目

在评价能源动力工程项目时应该采用综合的评价方法，考虑技术、经济和环境等因素。叙述了一种基于总资源系统的综合评价方法，将生产中消耗的(包括污染掉的)空气、水和燃料等都折算成资源，并从社会平均边际削减成本的角度计算了利用资源对社会造成的外部成本。指出，计算资源的价值时必须包括其外部成本，并计入最终的总成本。文中还陈述了综合评价方法的原理，并以某燃天然气的燃气轮机联合循环热电联产系统为例子，与燃煤热电联产系统进行了比较。

Evaluation of Energy Resource Utilization Projects from the Viewpoint of Resources

During the evaluation of energy resource utilization projects a comprehensive evaluation method should be used with technical, economic, environmental and other related factors being taken into account. The authors have described a comprehensive evaluation method based on a total resource system. Under this method air, water and fuel, etc consumed (including those expended by pollution) in production are converted into material resources. Moreover, from the viewpoint of social average marginal cost cut calculated is the external cost to the society due to the utilization of resources. It is noted that during the calculation of resource values the external cost must be included and be listed into the final total cost. Furthermore, the principles of this comprehensive evaluation method are also expounded. A combined cycle cogeneration power plant involving a natural gas fired gas turbine is compared with a coal fired cogeneration power plant system. The results of this comparison demonstrate that the evaluation of power projects from the viewpoint of resource utilization is fully justified.
