【摘要】：城市集中供热作为一项民生工程,是国家在基础建设领域中重点支持的行业。随着我国城市化进程的不断加快,建筑面积不断增加,为了解决新增加用户的采暖需求,改善原有用户的供热服务质量,需要对现有供热系统进行改造。同时,随着我国经济的快速增长,资源能源消费约束明显显现,能源供求矛盾日益突出,作为能源消耗大户,供热行业节能降耗迫在眉睫,因此需要在改造前深入分析现状,找出能源浪费的环节,提出有针对性的改造措施,对于改善供热运行、提高供热服务质量、节能降本,实现企业的良性发展有着重要的意义。本文正是在此背景的基础上形成的,论文从拟改造工程现状入手,介绍了项目目前的能源利用基本情况,分析各用能系统能源损失的环节,找出存在的问题,在借鉴国内外同行业先进经验的基础上,提出了供热改造工程的节能实施方案并对方案实施后的节能效益及经济效益作出了评价,评价结果表明该工程的各项效益非常显著。文中运用能量平衡的理论和分析方法对现有供热系统中的燃煤系统、电力系统、用水系统进行了分析,从设备、工艺等不同角度阐述项目改造中节能评估的应用,与现有情况对比,得出项目改造后的实施效果。本文通过对供热系统进行能耗分析及改造,得出了有实际应用价值的结论,为今后供热改造工程中的节能评估研究提供一些有价值的参考。
[Abstract]:Urban central heating, as a livelihood project, is a key industry supported by the state in the field of infrastructure construction. With the development of urbanization in China, the building area is increasing. In order to solve the heating demand of the new users and improve the heating service quality of the original users, the existing heating system needs to be reformed. At the same time, with the rapid economic growth of our country, resource and energy consumption constraints appear obviously, the contradiction between energy supply and demand is increasingly prominent. As a large energy consumer, energy saving and consumption reduction in the heating industry is imminent, so it is necessary to analyze the present situation thoroughly before the transformation. It is of great significance to find out the links of energy waste and put forward the corresponding measures to improve the operation of heating, improve the quality of heating service, save energy and reduce the cost, and realize the benign development of the enterprise. This paper is formed on the basis of this background. This paper introduces the basic situation of energy utilization of the project, analyzes the links of energy loss in each energy use system, and finds out the existing problems from the point of view of the present situation of the project. On the basis of drawing lessons from the advanced experience of the same industry at home and abroad, this paper puts forward the energy saving implementation scheme of the heating supply renovation project and evaluates the energy-saving benefit and economic benefit after the implementation of the scheme. The evaluation results show that the benefits of the project are very remarkable. In this paper, the energy balance theory and analysis method are used to analyze the coal burning system, electric power system and water use system in the existing heating system, and the application of energy saving evaluation in the transformation of the project is expounded from the different angles of equipment, technology, etc. Compared with the existing situation, the implementation of the project after the transformation effect. Based on the energy consumption analysis and retrofit of the heating system, this paper draws a conclusion with practical application value, and provides some valuable references for the energy conservation evaluation research in the future heat supply renovation project.
