瑞光集中供热工程热网方案的比选

针对某热网工程地形落差大、输送距离长、压力等级控制以及联网供热等情况,对设置隔压换热站、中继泵站、采用分布式变频、电厂首站循环泵外移几种方案从技术、经济、运行及可实施性等方面进行了分析,最后得出采用隔压换热站方案较好的结论。

On comparison of heating network schemes for central heating projects of Ruiguang

According to the status of the large drop height of the topological of the heating network,the long transmission distance,the pressure degree control and the networking heating,the paper analyzes some schemes,including the allocation of the pressure heat exchanging stations,the booster pump station,adopts the distributed variable frequency and out-shift of the first circulating pump of the power plant from the technology,the economy,the operation,and the implementation,and concludes the adoption of the pressure heat exchanging stations is better.
