200MW汽轮机组五段抽汽温度异常变化的分析处理
摘要
介绍鹤壁煤电公司200MW汽轮机组五段抽汽温度异常变化的分析和处理。通过各项检查试验
找出了五段抽汽温度异常变化的原因为轴封一段漏汽排挤五段抽汽所致
对此进行了相应的消缺处理后恢复正常。
Abstract
The treatment for abnormal variation of the fifth stage extraction steam temperature concerning 200 MW steam turbine unit in Hebi Power Plant has been presented. Through various inspection and test
the cause leading to abnormal variation of fifth stage extraction steam temperature has been found to be the result of leakage from shaftpacking no.1 pushing the fifth stage extraction steam out
and correponding treatment for eliminating the said defect being carried out.
