摘　　要：北京高井热电厂1、2号机组通流技术改造中,低压通流部分应用了蜂窝式汽封。通过改造解决了低压前后轴封漏汽掉真空问题,增强叶顶汽封的去湿效果,提高了机组运行的经济性和安全性。In the technical retrofit of the flow passage for No. 1 and No. 2 units in Beijing Gaojing Cogeneration Power Plant, the cellular steam seal was applied to the low pressure flow passage. After the retrofit, steam leakage and reduction of vacuum in the front and back low pressure shaft seals are solved, and＂ the dehumidification of the blade tip steam seal is reinforced. The economy and safety of the unit are thus improved.
