Desulfurization Flue Gas Desulfurization Project Economic Evaluation Model For The Design And Development Of Licensed Business Projects

The rapid development of Flue Gas Desulfurization Industry causes the problems such as the quality failure of some FGD projects, low operation efficiency of FGD devices, the poor operation maintenance. To improve the construction quality of the FGD facilities, the National Development and Reform Commission and State Environmental Protection Administration organized pilot program for FGD BOT for coal-fired power plants. The FGD BOT model is favorable for integration of resources, improvement of capital structure. The FGD projects for power plant operating in such model will help realizing the environmental industrialization, creating benefits for investor, creditor, and achieving the goal of emission reduction, that will contribute to the built of energy-saving and environmental friendly sociality. Adoption of the FGD BOT model goes in parallel with the national policy. As CPI Yuanda Environmental Protection Engineering Co., Ltd meets the requirements on technology, operation management, reserve of talents and financing capacity, the key factor for operating the FGD BOT model is the economic feasibility of the FGD project in power plants.Therefore, in this article, it studies the economic feasibility of the FGD BOT in detail, which can be summarized in following 3 aspects: firstly establishing the financial and economic evaluation system; Secondly taking the 2×600MW units FGD project of the CPI Jiangxi Xinchang Power Company as subject, to expound and prove in detail the Financial and Economic Evaluation System for FGD BOT project; Finally analyzing and elaborating the application value of financial and economic evaluation system for the FGD BOT project. The main contents in this paper include:(1) The possibility research of this FGD project include: the possibility of technology, the possibility of economy, the possibility of operation and the possibility of society.(2) We discuss the requirement of, such as how to study the issue, how many functions in this system, what kind of relationship among different data. The requirement of function exactly follows the rules of the programming development; we build the layered DFD and data dictionary. At the same time we also build entity-relationship graphics for data requirement.(3) Then in the procedure of design of FGD project model, we build the software structure chart and database. At the same time we build all kinds of data tables of this system.(4) From the discussion and design of this economy evaluation model in FGD project, we use VB.NET language, SQL SERVER2005 language to develop the system.The Gross Revenue of FGD BOT project consists of desulfurization tariffs revenue and the desulfurization by-products sales revenue. The movement of online electricity quantity of power plant is in direct proportion to the desulfurization tariffs revenue, when receiving the same subsidy on desulfurization tariffs, which means the online electricity quantity, is higher and the desulfurization tariffs revenue gets higher. The operation costs of FGD project comprises of fix cost, variable cost and financial cost. The variable cost is in direct to the operation cost. By analyzing the project income, costs, making Cash Flow table, to define the economic feasibility of the project and make proper investments with the financial and economic evaluation indicators such as the project internal rate of return, net present value, return period of investment.
