在已经建成和即将建成的大型集中供热系统中,有相当部分是利用发电厂的余热作为热源,循环冷却水作为供热介质,以低温(50—70℃)大流量的工况条件下进行供热。能够利用发电厂一部分余热是这种方式的突出优点,但是也存在着管网腐蚀和结垢问题。
In the large-scale centralized heating system that has already been built and is about to be completed, a considerable part of it uses the waste heat of the power plant as a heat source and the circulating cooling water as a heating medium under the condition of low temperature (50-70 ° C) high flow rate Heating. The ability to harness part of the heat generated by power plants is a salient advantage of this approach, but there are also pipe network corrosion and scale problems.
