摘　　要：某火电厂汽轮机运行十余年,油液监测过程中,因颗粒污染度测试结果持续偏高,进而对其他相关项目进行深入分析。结果表明,油品抗氧化性能下降,易生成极性软颗粒物质,是导致油品颗粒污染度含量偏高的重要原因。The steam turbine of a thermal power plant has been in operation for more than a decade.In the oil monitoring process,the particle pollution level was tested to be high continuously.Accordingly,in-depth analyses were conducted on other related items.The results show that the anti-oxidation property of the oil declines,allowing the possible generation of soft polar particles,which is an major cause for the high particle pollution level of the oil.
