集中供热换热站设计_精品.doc

摘要 随着人们生活水平的提高，集中供热被越来越多地采用。发展集中供热是一项公益性工程，是城市建设的基础设施之一，具有节约能源、改善环境、提高供热质量等综合效益，同时采用集中供热可提人们的生活质量。利用集中供热代替小锅炉和家用小煤炉供热，已成为势在必行的发展方向。间接连接供热因其热源补水率低，热网的压力工况和流量工况不受用户的影响，便于热网运行管理，在近年来已经成为流行的供热方式,本设计也采用了间接连接供热。 关键词：集中供热；换热站；热负荷 Abstract With the improvement of people’s life. The district heating system has been used more and more.Developing district heating is a commonweal work and is an important project of a city It has many benefits,such as,energy saving,improving environment,improving heating quality,and so on.At the same time district heating can improving the quality of people’s life.taking advantage of district heating system to replace small coal stove home heating has become the imperative direction of development. This article describes the design of a district heating station in Hohhot. According to the principle of saving investment,energy saving and satisfying the heating effect, Focusing on the heat load of heating station，identification, equipment selection, conditioning and heating system, insulation and other aspects.
