【摘要】：自2006年1月1日起,天津市执行第Ⅱ时段环保标准,即火电厂燃煤锅炉S02排放浓度低于100mg/m3,烟尘排放浓度低于30mg/m3。而2008年前国华盘山发电厂烟气SO2排放浓度为763mg/m3,大大高于天津市地方排放标准要求,因此,国华盘山发电厂脱硫工程项目十分紧迫。首先,本文从设备及运行状况、燃煤及元素分析以及烟气污染排放等方面,介绍了国华盘山电厂脱硫工程项目的基本情况,阐述了电厂脱硫工程项目建设的重要性和成本控制的必要性。然后,本文对两种主要的烟气脱硫工艺特点进行了比较,发现石灰石-石膏湿法虽然成本高,但是因其能满足地方政府二氧化硫排放浓度要求,所以是国华盘山发电厂脱硫工艺的合适选择,但也给该项目的成本控制带来了压力。此外,该项目的五大特点也对该项目的成本控制具有负面影响。再后,本文分别对脱硫工程项目筹备阶段的成本管理、正式施工阶段的成本管理以及项目竣工之后的成本核算管理进行了深入分析,研究表明国华盘山脱硫工程项目在筹备阶段,通过优化工艺设计,有效降低了设备成本。但是,也存在成本预测偏差较大、合同管理约束性不强,以及成本管理制度不健全等成本管理问题；在项目施工阶段,存在质量成本管理问题、工期成本管理问题及材料和工器具成本管理问题；在项目竣工阶段,存在成本核算不准确,成本费用分配不合理问题。最后,本文提出了国华盘山发电厂脱硫工程项目成本管理问题带来的启示。
[Abstract]:Since January 1, 2006, Tianjin has implemented the second time environmental protection standard, that is, the S02 emission concentration of coal-fired boiler in thermal power plant is below 100 mg / m ~ (3), and the smoke emission concentration is less than 30 mg / m ~ (3). The SO2 emission concentration of flue gas in Guohua Panshan Power Plant before 2008 is 763 mg / m ~ 3, which is much higher than the requirement of Tianjin local emission standard. Therefore, the desulfurization project of Guohua Panshan Power Plant is very urgent. First of all, this paper introduces the basic situation of desulfurization project in Guohua Panshan Power Plant from the aspects of equipment and operation condition, coal combustion and element analysis and flue gas pollution emission. The importance of power plant desulfurization project construction and the necessity of cost control are expounded. Then, the characteristics of two main flue gas desulphurization processes are compared. It is found that although the cost of limestone-gypsum wet method is high, it can meet the requirement of local government sulfur dioxide emission concentration. So it is a suitable choice for desulfurization process in Guohua Panshan Power Plant, but it also brings pressure to the cost control of the project. In addition, the five features of the project also have a negative impact on the cost control of the project. After that, this paper analyzes the cost management of desulfurization project preparation stage, the cost management of the formal construction stage and the cost accounting management after the completion of the project, respectively. The research shows that in the preparatory stage of Guohua Panshan desulfurization project, the equipment cost is reduced effectively by optimizing the process design. However, there are also some cost management problems, such as large deviation of cost prediction, weak binding of contract management, and imperfect cost management system, etc. In the construction phase of the project, there are problems of quality cost management, During the completion stage of the project, the cost accounting is inaccurate and the cost allocation is unreasonable. Finally, this paper puts forward the inspiration of cost management of desulfurization project in Guohua Panshan Power Plant.
