【摘要】：电力作为国民经济的基础产业,对社会经济的发展起着不可替代的支撑作用,除了保障电力能源的供应,同时也承担着越来越多的社会民生责任,其中最重要的就是环保和可持续发展的社会责任。在我国目前以火电为主的装机结构中,燃煤不可避免的造成大量污染物的排放,其中氮氧化物是大气的主要污染物之一,是造成酸雨和化学烟雾的主要原因。自我国实行严格的《火电厂大气污染物排放标准》(GB13223—2011)以来,火电厂的燃煤脱硝系统技术改造大范围展开。脱硝系统改造工程减少了氮氧化物的排放,具有显著的环境效益和社会经济效益,进行项目综合效益评价有利于发电企业及时总结经验,客观准确反映改造效果,为后续技术改造工程项目的顺利实施提供经验。本文首先分析了国内外项目综合效益评价、火电厂技改项目后评价和模型,对评价目前的研究现状也进行了梳理,然后通过对准格尔电厂脱硝系统技术改造项目进行充分调研,结合笔者实际工作经验对准格尔电厂脱硝技改工程概况进行阐述,重点对项目实施过程中的项目管理情况及项目的社会经济影响进行分析。在此基础上,本文根据综合评价指标体系建立原则,构建了准格尔电厂脱硝系统技改项目综合效益评价多层次指标体系,并对指标内涵进行说明。然后结合综合评价理论,本文建立了基于熵权-TOPSIS法的脱硝技改综合效益评价模型,通过数据处理、权重计算等实证研究,对项目管理水平、环境影响及社会经济影响三方面进行了综合评价,得到准格尔电厂脱硝改造项目效益总体处于行业中上等水平的结论。最后依据工程实际、评价结果及工作经验提出针对我国火电厂技术改造项目相应的政策、管理及技术方面的建议。本文从实际工作经验出发,结合综合评价方法论,对准格尔电厂脱硝技术改造项目综合效益进行后评价研究。随着我国火电厂超低排放标准的实施,火电厂技改项目进一步增加,及时进行脱硝技改项目后评价研究可为燃煤电厂脱硝技改项目提供经验和理论支持,有助于改善生态环境,提高企业管理水平,提高改造项目的工作及投资效率,同时有利于促进环境友好型社会建设,实现满足社会公共利益的可持续发展。
[Abstract]:As the basic industry of the national economy, electric power plays an irreplaceable supporting role in the development of social economy. In addition to ensuring the supply of electricity energy, it also bears more and more social and livelihood responsibilities. One of the most important is environmental protection and sustainable development of social responsibility. In the present installation structure of thermal power plants in China, coal combustion inevitably causes a large number of pollutants emissions, among which nitrogen oxide is one of the main pollutants in the atmosphere and the main cause of acid rain and chemical smog. Since the implementation of strict Atmospheric Pollutant discharge Standard (GB13223-2011) in thermal power plants, the technical transformation of coal-fired denitrification system in thermal power plants has been carried out on a large scale. The revamping project of denitrification system reduces the emission of nitrogen oxides and has remarkable environmental and social economic benefits. The comprehensive benefit evaluation of the project is beneficial to sum up the experiences of power generation enterprises in time and to reflect the effect of transformation objectively and accurately. To provide experience for the successful implementation of subsequent technical transformation projects. This paper first analyzes the comprehensive benefit evaluation of domestic and foreign projects, the post-evaluation and model of the technical transformation project of thermal power plant, and combs the current research status of the evaluation, and then through the full investigation of the technical transformation project of denitrification system in Zhungel Power Plant. Combined with the author's practical work experience, the general situation of denitrification technical reform project in Zhungel Power Plant is expounded, and the project management situation and the social and economic impact of the project are analyzed. On this basis, according to the establishment principle of comprehensive evaluation index system, a multi-level index system for comprehensive benefit evaluation of denitrification system in Zhungel Power Plant is constructed, and the connotation of the index is explained. Then combined with the theory of comprehensive evaluation, this paper establishes the comprehensive benefit evaluation model of denitrification technology reform based on entropy weight and TOPSIS method. Through the empirical research such as data processing, weight calculation and so on, the level of project management is analyzed. The comprehensive evaluation of environmental impact and social and economic impact has been carried out, and the conclusion has been drawn that the benefit of denitrification project of Zhungel power plant is generally in the middle and upper level of the industry. Finally, according to the engineering practice, the evaluation results and working experience, the corresponding policy, management and technical suggestions for the technical transformation project of thermal power plant in China are put forward. Based on the practical work experience and the comprehensive evaluation methodology, this paper makes a post-evaluation study on the comprehensive benefit of the technical transformation project of denitrification in Zhunger Power Plant. With the implementation of ultra-low emission standards for thermal power plants in China, the technical transformation projects of thermal power plants are further increased. Timely evaluation of denitrification projects can provide experience and theoretical support for the technical transformation projects of coal-fired power plants, and help to improve the ecological environment. At the same time, it is helpful to promote the construction of the environment-friendly society and to realize the sustainable development which satisfies the public interests of the society.
