国务院下达的节能四号指令中,强调采暖用汽单位限期把汽暖改为水暖,以减少能耗。本文介绍一种新型板式换热器应用于汽暖改水暖系统中的使用情况,以供有关单位参考。 关于用板式换热器搞汽一水换热,並不算是新的尝试。82年我们曾在北京仪器厂应用ZW1000型蛛网伞板式换热器在汽一水换热方面搞过测试,实际使用效果还是可以的。但是,由于ZW型换热器本身周边长,密封结构欠佳,因此,当该设备间歇工作
The State Council issued an energy-saving directive No. 4 that emphasizes that the heating steam unit must change the steam heating to plumbing in order to reduce energy consumption. This article describes the use of a new type of plate heat exchanger in the application of steam heating to water heating systems for reference by relevant parties. Regarding the use of plate heat exchangers for steam and water heat transfer, it is not a new attempt. In the year of 82, we used ZW1000 cobweb plate heat exchanger in Beijing Instrument Factory to conduct tests on the heat transfer of steam and water. The actual use effect is still possible. However, due to the long circumference of the ZW heat exchanger itself, the sealing structure is poor, so when the equipment is intermittently operated
