Abstract:

Based on the centralized heat supply system of a certain area, the hydraulic calculation method for dendritic and ring pipeline was introduced. Circulating resistance of dendritic and ring pipeline was calculated and compared based on different work condition. It was indicated that ring pipeline take advantages than dendritic pipeline on operation energy consumption and reliability in certain work condition. Which has certain value for promotion and implementation.

Key words:

centralized heat supply, dendritic pipeline, ring pipeline, hydraulic calculation, circulating resistance
