【摘要】：随着全球气候变化,温室气体排放问题成为全球各国关注的焦点。另外我国多地雾霾严重,环保部不断提高环境保护标准,我国非常重视洁净煤燃烧和脱硫脱硝技术项目管理的开发和应用,21世纪,我国加快了NOx污染政策的发展和相应立法,2003年12月颁布了火电厂大气污染物排放标准(GB13223-2003)根据时段和燃料特性进行了修订,规定了燃煤锅炉的NOx排放限值,除了地方政府根据当地实际情况,已经颁布了更严格的地方排放标准。2010出版了火电厂大气污染排放标准,指出自2014年7月1日起,现有煤燃烧式动力锅炉和燃气轮机实施氮氧化物200mg/m3限制;新型燃煤动力锅炉和燃气轮机执行氮氧化物100mg/m3限制。我国不仅从政策上进行约束,也在通过完善环境保护经济补偿政策,对于进行脱硫脱硝除尘改造的燃煤机组,政府也在上网电价给予补偿。而对于未进行超低排放改造的电厂,则制定经济惩罚政策或者减少安排计划电量。在超低排放政策明确的情况下,通过降低全寿命周期成本,将有利于提高机组的经济性。本文首先阐述了全寿命周期成本管理理论、计算流程和方法,结合煤电项目超低排放改造的项目特征,分析了燃煤电厂超低排放改造项目全寿命周期成本管理方法应用的可行性。详细研究了燃煤电厂超低排放改造工程的LCC分解和各个成本影响因素分析。最后,结合某案例(2×330MW机组)超低排放改造项目进行研究分析。在保证环保排放达标、机组安全稳定运行的基础上,对超低排放改造的全寿命周期全寿命造价进行分析,选择出最适宜的技术路线,规避改造过程中及改造后的经济风险,在全生命周期内成本最优化。该方法有利于从经济的角度优化燃煤电厂超低排放改造的成本。
[Abstract]:With the global climate change, greenhouse gas emission has become a global concern. In addition to our more severe haze, the Ministry of environmental protection, constantly improve the standard of environmental protection, our country attaches great importance to clean coal combustion and desulfurization and denitration technology development and application of project management in twenty-first Century, China has accelerated the development of NOx pollution and corresponding policies the legislation was promulgated in December 2003, thermal power plant air pollutant emission standards (GB13223-2003) according to the time and fuel properties were revised, the provisions of the coal-fired boiler NOx emission limits, in addition to the local government according to the local actual situation, has promulgated the.2010 more stringent emission standards published emission standard of air pollutants for thermal power plants, pointed out in July 1, 2014 since the existing coal combustion power boilers and gas turbines to implement nitrogen oxides 200mg/m3; new coal-fired power boiler and gas turbine to perform nitrogen The oxide 100mg/m3 limit. China is not only the constraints from the policy, also through the improvement of economic compensation policy for environmental protection, coal-fired units desulfurization denitration dust transformation, government compensation in the tariff. As for non ultra low emission transformation of the power plant, making economic policy or plan to reduce the punishment power. In the ultra low emissions policy clear, by reducing the life cycle cost, will help to improve the economic efficiency of the unit. This paper describes the whole life cycle cost management theory, calculation method and process, combined with the project characteristics of ultra low emission coal power project transformation, the paper analyzes the feasibility of application of life cycle cost management method of coal ultra low emission power plant renovation project. Detailed analysis on effect of ultra low emission coal-fired power plant renovation project LCC decomposition and various cost factors. Finally,. One case (2 * 330MW unit) of reconstruction project of ultra low emission. In order to ensure the environmental emission standards. The foundation of safe and stable operation of the unit on the entire life cycle of the transformation of ultra low emission life-cycle cost analysis, choose the most suitable technology route, and after the transformation of the economic transformation process of risk aversion in the full life cycle cost optimization. This method is conducive to optimizing from the economic point of coal-fired power plants with ultra low emission transformation costs.
