城市大型热源联网运行管网布置方案的探讨

Investigation of Arrangements of Central Heating Supplied by Joint Large-scale Heat Sources

城际大型热源联网运行具有明显的社会、环境和经济效益,能有效地提高集中供热的安全性和质量.在分析联网运行制约因素的基础上,提出了一种新的联网方案串联热源的同程式供热管网方案,即通过相互间加热回水,联网的各热源将各自的热量转移到城市的集中供热管网,各供热区间的管网布置为同程式.并对该方案进行了初步的分析和研究,着重讨论了其在水力工况和水力稳定性方面的性质.

The operating mode of combining several large-scale heat sources into an integrative heating system of a whole city has obvious social benefits, environmental benefits and economic benefits. It can effectively improve the heating quality and heating security. A mode of central heating supply system which is powered by a joint of several large-scale heat sources is put forward and studied in this paper. And the pipe arrangement of it is of a reversed return type which is studied here with focus on hydraulic status of the pipe network and hydraulic stability.
