The Hydraulic Calculation and Reformation Application of Yuhua Heating Network in Shijiazhuang Based on Graph Theory

Abstract:

In heat source ability sufficient situation, Yuhua network in Shijiazhuang had some phenomenon, such as uneven heating, serious disorders, the far-end heating reliability was insufficient. Based on the basic principle of Graph theory, this article carried on the detailed hydraulic calculation to the annular pipe network, determined and implemented the reasonable transformation program, finally carried on the investigation and study test to the actual operation network after reformation. The results show that after reformation, the actual heating network runs well, improves the heating security and reliability, so the hydraulic calculation method based on Graph theory is accurate, and has certain guiding sense to other pipe networks' energy conservation reformation.
