北京6个热力站系统节能诊断与节能潜力分析

Energy-Saving Diagnosis and Energy-Saving Potential of Systems in Six Thermal Stations of Beijing

通过对北京市6个热力站系统能耗和水耗的统计,分别从热工性能和气象条件分析了其节能潜力。基于热工性能的不同,各个站节能率在11%～31%,总节能率为12%;基于气象条件的不同,6个热力站中节能率最大的为11%,最小的为3%,总节能率为5%。节能率可通过管网平衡调节,减少部分负荷下的过热度来实现。

With statistics of energy consumption and water consumption in six thermal stations at Beijing,energy-saving potential is analyzed respectively from the thermal performance and weather conditions.The energy-saving rate of each station is 11%~31%,the total energy-saving rate is 12%,based on various thermal performance;the maxium energy-saving rate of six thermal stations is 11%,the minimum is 3%,and the total energy-saving rate is 5%,based on various weather conditions.The saving rate will be adjusted through balancing the pipe network and reducing overheating under part of load.
