承德某区域集中供热设计

Central Heating Design for One District of Chengde

本文针对区域复杂的地形环境、热源的局限性以及城市现状与未来的发展对供热的需求差别,经综合分析比较,该集中供热系统采取短期直供,待电厂具备抽汽加热能力之后改为间接供热的形式。阐述了直供中为克服地形高差大等设计难题而采取的在系统主管网上设置减压站、中继泵站等一系列安全措施。运行情况表明该系统设计是成功的。

Viewing the complex condition of the district,the limit of heat source and the distinct demand between nowadays and future. The district is supplied with direct-heating in short-duration;but be supplied with indirect-heating in future when the power plant owns the capacity to pump steam.Points out assuring measures such as setting decompress station and relay station to overcome the hypsography difficulty.
