本市供热系统节能改造的试点单位——上海助剂厂,对拥有16吨/时锅炉一台、4吨/时锅炉二台和926米蒸汽管道组成的热网进行了节能技术改造。选用上海电力保温材料厂生厂的微孔硅酸钙作主保温材料,减少了管道散热损失。经改造后,蒸汽管网平均壁温与环境温度之差由原来的12.5℃下降为6℃,管道总散热损失比改造前下降47.87%,
The city heating system energy-saving pilot unit - Shanghai Additive Factory, has a 16 tons / hour boiler, 4 tons / hour boiler and 926 meters of steam pipe heating network composed of energy-saving technological transformation. Use Shanghai Power Insulation Materials Factory Health Mill porous calcium silicate as the main insulation material to reduce the pipeline heat loss. After the transformation, the difference between the average wall temperature of the steam pipe network and the ambient temperature dropped from 12.5 ℃ to 6 ℃, and the total heat loss of the pipe decreased 47.87%
