锅炉高温大温差运行对供热能耗的影响研究

Research on Influence of Boiler Operation in High Temperature and Big Temperature Difference on Heating Energy Consumption

针对供热系统锅炉一次管网的高温运行和低温运行哪个节能的问题,通过实际调研获得当前北京市供热采暖系统实际运行现状。对2种运行方式的管道散热损失、输送能力、管道投资、水泵耗能等方面进行计算,通过对比得出锅炉一次管网在高温大温差运行时对供热节能更有利。

Aiming to the problems of boiler operation in high temperature or low temperature which is more favorable for energy saving, the current practical operation condition of Beijing heating was obtained by survey. Heat loss, delivery capacity, cost of pipeline and pump energy consumption of the two different operation modes were calculated, and the comparative result shows that boiler operation in high temperature and big temperature difference is more favorable for heating energy consumption.
