冷凝器空气泄漏标准的探讨

Discussion on the Standard of Air Leakage in Condensers

电站汽轮机凝汽器真空的维持对于机组运行的经济性和安全性的影响重大,目前的真空泄漏标准一直沿用《电力建设施工验收技术规范》的相关规定,现场反映这个标准太松。结合制造厂及现场泄漏率的计算,期望能得到一个更合理的泄漏标准,对今后标准的制订有一定的参考价值。

The vacuum of steam turbine condensers is of great importance for the economic and safe operation of power plants. Currently,the standard on vacuum leakage adopts the related specifications in the industrial standard but the feedback shows that it is not strict enough. Based on the calculation on leakage rate conducted by manufactures and users separately, a more reasonable leakage rate is obtained, which may be helpful for future 's standard establishment.
