The Energy-Saving Analysis of District Heating System

This paper introduces the adjustment curve equations of district heating system commonly used in secondary network. On this basis, adjustment curve equations of the adjustment that combines quantity adjustment and quality adjustment are proposed. Then taken a community in Zhangjiakou as an example, we compare the power consumption of the adjustment scheme proposed in the paper with that of quality adjustment and quality adjustment with different quantitative ratio in each period. The analysis shows that the adjustment scheme has much more potential in energy-saving.
