Study On The Feasibility Of Feed Water Pump Reconstruction Project Of Songhuajiang Thermal Plant

Engineering economic analysis is the study of engineering and economicproblems, the project as the main body, the technical and economic system as the core,to study how the effective use of resources, improve the economic benefit. Researchon technical scheme of various engineering economic analysis of engineeringeconomy, various techniques in the use of the process to obtain with the smallestinvestment expected output or how to amount of investment for maximum output,how to realize the product, operation and services necessary function with the lowestlife cycle cost. In history, many important engineering technical mistakes not for thereason of science and technology, but the economic analysis of acalculia. Engineeringeconomic analysis, with particular emphasis on improving and optimizing theequipment function in the detail aspect, focus on docking equipment and processesand consensus, in order to achieve the production management objective: less input,more output, obtain the best economic benefit.At present, the electric power development has entered the stage of marketeconomy, power plant management is not just for stability full hair, also make full useof primary energy, provides the high quality power to the society, in the mosteconomic cost and more power, more power, and ultimately to multi settlementquantity of electricity, improve economic efficiency for the purpose; and some unitsthermal power plant is still extensive management, technology, high energyconsumption and other issues. Therefore, the implementation of transformation in thecomprehensive upgrading existing coal-fired electricity generating units, to improveenergy efficiency of resource use, promote the electric power industry to acceleratethe transformation of the mode of development, has the vital significance to building aresource conserving, environment-friendly society.In this paper, Songhua River power plant as an example, conducts the research tothe operation mode of feed water pump project. To the water pump operation modetransformation project is not only an important way to solve the Songhua River powerplant high energy consumption and improve economic efficiency, but also plays animportant role in the social and economic development, social and economic benefit etc.. Therefore, this paper studies the practical work of other thermal power plantsalso have guidance and reference value.This paper mainly to the Songhua River power plant phase transformationoperation mode of feed water pump of2*125MW units (4, Motor-Driven FeedwaterPump into steam feed pump) as an example, to give the operation economy of thepump as the research object, analysis of operation mode of feed water pump in thetechnical and economic aspects of the problem, by using engineering economicanalysis and other related theories put forward the reform plan, in order to achieveenergy saving, economic power, and to improve the economic benefits. At the sametime, this article from the conservation of coal and water resources, to improve theenvironment, expounds the necessity and significance of feed water pump operationmode transformation project. In this paper, according to the enterprise productionoperation data collected in recent years, technical and economic focus from operationof feed water pump reform aspect (selection and layout of equipment) are optimizeddesign, to make the operation of the unit in a reasonable manner. At the same time,the comprehensive analysis and evaluation on the operation mode of feed water pumpretrofit scheme of the operation mode, water pump, to pump the economytransformation of investment, risk, and so on, especially in the better development andutilization of production resources, new production technology, in the energy-savingemission reduction, improving economic efficiency, obtained remarkable the effectof.Finally, through the analysis of the transformation and economic effect and aftertransforming social impact analysis, further proved the significance of this paper; atthe same time, but also to the economic operation of the equipment managementpersonnel Songhua River power plant optimization and improvement to provide agood idea.
