【摘要】：氮氧化物是大气主要污染物之一,随着国家对生态环境的重视,相关部门出台了与火电厂脱硝相关的标准、规划、电价补偿等政策,以此促进火电厂氮氧化物减排的实施。因此火电厂脱硝系统,尤其是主流的选择性催化还原(selective catalytic reduction,SCR)脱硝装置正被广泛的应用于发电企业的生产中,脱硝成本也直接影响着发电企业的收益情况。然而,目前对脱硝成本的研究仍旧比较有限,缺乏针对成本及其影响因素的定量研究,不利于发电企业精细化的成本管理。论文对燃煤电厂脱硝项目投资与运行成本的影响因素及数学模型进行了研究。首先论述了国内外脱硝技术的发展应用情况和脱硝成本的研究现状,并结合脱硝工艺,定性分析了脱硝投资与运行成本的影响因素,在此基础上设计了问卷调查表。完成数据的收集后,对45个火电厂共计86台燃煤机组脱硝项目投资与运行成本的相关数据进行了处理与分析,理清了单个因素对成本的影响。其次,应用灰色关联分析理论和多元回归分析理论,分析了脱硝投资成本、还原剂成本、催化剂更换量和脱硝工艺厂用电率的影响因素及其影响程度,建立了火电厂脱硝还原剂成本的数学模型,探讨了投资成本、催化剂更换量和脱硝工艺厂用电率的数学模型。最后,结合本文分析的结果,对火电企业脱硝成本的降低途径及措施提出了建议。
[Abstract]:Nitrogen oxide is one of the main atmospheric pollutants. With the attention of the country to the ecological environment, relevant departments have issued policies related to denitrification of thermal power plants, such as standards, planning, electricity price compensation, and so on, in order to promote the implementation of nitrogen oxide emission reduction in thermal power plants. Therefore, the denitrification system of thermal power plant, especially the mainstream selective catalytic reduction unit, is widely used in the production of power generation enterprises, and the denitrification cost directly affects the income of power generation enterprises. However, the research on denitrification cost is still limited, the lack of quantitative research on cost and its influencing factors is not conducive to the meticulous cost management of power generation enterprises. The paper studies the influencing factors and mathematical models of the investment and operation cost of denitrification project in coal-fired power plant. Firstly, the development and application of denitrification technology at home and abroad and the research status of denitrification cost are discussed. Combined with denitrification process, the influencing factors of denitrification investment and operation cost are qualitatively analyzed. Based on this, a questionnaire is designed. After the data collection is completed, the data related to the investment and operation cost of 86 coal-fired units in 45 thermal power plants are processed and analyzed, and the influence of single factor on the cost is clarified. Secondly, by using the theory of grey correlation analysis and multivariate regression analysis, the factors affecting the investment cost of denitrification, the cost of reducing agent, the quantity of catalyst replacement and the power consumption of denitrification craft factory are analyzed. The mathematical model of the cost of denitrification reductant in thermal power plant is established, and the mathematical models of investment cost, catalyst replacement amount and electric power rate of denitrification craft factory are discussed. Finally, based on the results of this paper, some suggestions are put forward to reduce the denitrification cost of thermal power enterprises.
