蒸汽冷凝水有效回收是燃煤供热系统节能降耗的有效手段,分析了一些企业未能充分回收利用的原因,从回收系统的设计原理、回收装置和系统监测与控制的设计入手,提出了充分回收利用蒸汽冷凝水的有效措施,并通过在燃煤供热烘干系统的应用所得到的数据对比,验证密闭式回收系统在节能降耗中产生的效益。 The effective recovery of steam condensate water is an effective measure to save energy and reduce consumption of coal-fired heating system. The reasons why some enterprises can not fully recycle are analyzed. From the design principles of recovery system, the design of recovery device and system monitoring and control, The effective measures of fully recovering and utilizing steam condensate, and verifying the benefits of the closed recovery system in saving energy and reducing consumption by comparing the data obtained from the application of the coal-fired heating and drying system.
