| 摘 要： | 哈尔滨第三发电厂4号机组为哈尔滨汽轮机厂生产的600MW汽轮机,该机组在单阀切顺序阀调节后,发现机组2号瓦的瓦温明显升高,振动也明显增大,严重影响机组的安全运行。为此该厂与哈尔滨工业大学合作对4号机配汽方式进行了改造,本文分析了故障原因,介绍了配汽改造各方案,并对机组运行参数做了比较分析。采用新的顺序阀方案后,在保证安全性的基础上,降低了煤耗量,大大地提高了机组运行的经济性。

| Abstract: | The unit 4 of Harbin Third power plant is a 600 MW turbine generator unit made by Harbin Turbine Company.When operating at part load and appying the sequence-valve governing,the temperature of No.2 bearing is too high,and the vibration of the bearing is severe too.This paper discusses the reason that causes the bearing temperature rising while working at part load and a new multi-valve governing strategy was proposed.The results of field test show that the new multi-valve scheme can decrease the temperature and vibration of No.2 bearing.The fuel consumption can also decrease.And the economics of the unit can increase,while maintainning the safety. |
