【摘要】：電力作為國民經(jīng)濟(jì)的基礎(chǔ)產(chǎn)業(yè),對社會經(jīng)濟(jì)的發(fā)展起著不可替代的支撐作用,除了保障電力能源的供應(yīng),同時也承擔(dān)著越來越多的社會民生責(zé)任,其中最重要的就是環(huán)保和可持續(xù)發(fā)展的社會責(zé)任。在我國目前以火電為主的裝機(jī)結(jié)構(gòu)中,燃煤不可避免的造成大量污染物的排放,其中氮氧化物是大氣的主要污染物之一,是造成酸雨和化學(xué)煙霧的主要原因。自我國實(shí)行嚴(yán)格的《火電廠大氣污染物排放標(biāo)準(zhǔn)》(GB13223—2011)以來,火電廠的燃煤脫硝系統(tǒng)技術(shù)改造大范圍展開。脫硝系統(tǒng)改造工程減少了氮氧化物的排放,具有顯著的環(huán)境效益和社會經(jīng)濟(jì)效益,進(jìn)行項(xiàng)目綜合效益評價有利于發(fā)電企業(yè)及時總結(jié)經(jīng)驗(yàn),客觀準(zhǔn)確反映改造效果,為后續(xù)技術(shù)改造工程項(xiàng)目的順利實(shí)施提供經(jīng)驗(yàn)。本文首先分析了國內(nèi)外項(xiàng)目綜合效益評價、火電廠技改項(xiàng)目后評價和模型,對評價目前的研究現(xiàn)狀也進(jìn)行了梳理,然后通過對準(zhǔn)格爾電廠脫硝系統(tǒng)技術(shù)改造項(xiàng)目進(jìn)行充分調(diào)研,結(jié)合筆者實(shí)際工作經(jīng)驗(yàn)對準(zhǔn)格爾電廠脫硝技改工程概況進(jìn)行闡述,重點(diǎn)對項(xiàng)目實(shí)施過程中的項(xiàng)目管理情況及項(xiàng)目的社會經(jīng)濟(jì)影響進(jìn)行分析。在此基礎(chǔ)上,本文根據(jù)綜合評價指標(biāo)體系建立原則,構(gòu)建了準(zhǔn)格爾電廠脫硝系統(tǒng)技改項(xiàng)目綜合效益評價多層次指標(biāo)體系,并對指標(biāo)內(nèi)涵進(jìn)行說明。然后結(jié)合綜合評價理論,本文建立了基于熵權(quán)-TOPSIS法的脫硝技改綜合效益評價模型,通過數(shù)據(jù)處理、權(quán)重計(jì)算等實(shí)證研究,對項(xiàng)目管理水平、環(huán)境影響及社會經(jīng)濟(jì)影響三方面進(jìn)行了綜合評價,得到準(zhǔn)格爾電廠脫硝改造項(xiàng)目效益總體處于行業(yè)中上等水平的結(jié)論。最后依據(jù)工程實(shí)際、評價結(jié)果及工作經(jīng)驗(yàn)提出針對我國火電廠技術(shù)改造項(xiàng)目相應(yīng)的政策、管理及技術(shù)方面的建議。本文從實(shí)際工作經(jīng)驗(yàn)出發(fā),結(jié)合綜合評價方法論,對準(zhǔn)格爾電廠脫硝技術(shù)改造項(xiàng)目綜合效益進(jìn)行后評價研究。隨著我國火電廠超低排放標(biāo)準(zhǔn)的實(shí)施,火電廠技改項(xiàng)目進(jìn)一步增加,及時進(jìn)行脫硝技改項(xiàng)目后評價研究可為燃煤電廠脫硝技改項(xiàng)目提供經(jīng)驗(yàn)和理論支持,有助于改善生態(tài)環(huán)境,提高企業(yè)管理水平,提高改造項(xiàng)目的工作及投資效率,同時有利于促進(jìn)環(huán)境友好型社會建設(shè),實(shí)現(xiàn)滿足社會公共利益的可持續(xù)發(fā)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.
