【摘要】：自2006年1月1日起,天津市執(zhí)行第Ⅱ時段環(huán)保標準,即火電廠燃煤鍋爐S02排放濃度低于100mg/m3,煙塵排放濃度低于30mg/m3。而2008年前國華盤山發(fā)電廠煙氣SO2排放濃度為763mg/m3,大大高于天津市地方排放標準要求,因此,國華盤山發(fā)電廠脫硫工程項目十分緊迫。 首先,本文從設備及運行狀況、燃煤及元素分析以及煙氣污染排放等方面,介紹了國華盤山電廠脫硫工程項目的基本情況,闡述了電廠脫硫工程項目建設的重要性和成本控制的必要性。 然后,本文對兩種主要的煙氣脫硫工藝特點進行了比較,發(fā)現(xiàn)石灰石-石膏濕法雖然成本高,但是因其能滿足地方政府二氧化硫排放濃度要求,所以是國華盤山發(fā)電廠脫硫工藝的合適選擇,但也給該項目的成本控制帶來了壓力。此外,該項目的五大特點也對該項目的成本控制具有負面影響。 再后,本文分別對脫硫工程項目籌備階段的成本管理、正式施工階段的成本管理以及項目竣工之后的成本核算管理進行了深入分析,研究表明國華盤山脫硫工程項目在籌備階段,通過優(yōu)化工藝設計,有效降低了設備成本。但是,也存在成本預測偏差較大、合同管理約束性不強,以及成本管理制度不健全等成本管理問題；在項目施工階段,存在質(zhì)量成本管理問題、工期成本管理問題及材料和工器具成本管理問題；在項目竣工階段,存在成本核算不準確,成本費用分配不合理問題。 最后,本文提出了國華盤山發(fā)電廠脫硫工程項目成本管理問題帶來的啟示。
[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.
