汽轮机组抽汽反冲超速原因分析及改造

Causes Analysis and Improvement of Recoil Hypervelocity in Steam Turbine Seies Exhausting Air

煤矸石综合利用电厂采用的青岛产C6—3 43/0 49D52系列抽凝机组在抽凝工况运行的情况下,非正常打闸停机时,抽汽母管过热蒸汽反灌入汽轮机组低压缸,从而使汽轮机组"超速"运行,带来不安全隐患。经过分析与实践,提出改造方案。

Power plant with comprehensive utilization of waste is adopting C6-3.43/0.49D52 series air exhauster made in Qingdao,when air exhauster working in unnormal openning sluice gate,exhausting air pipe overheaded,steam flows low pressure vessal of steam turbine,it makes that steam turbine works in hypervelocity,this paper raises remaking programme through analysis and practice.
