摘要
某电厂2号机组抗燃油出现黑色颗粒物,经抗燃油处理设备处理后,黑色颗粒物仍时有时无。经扫描电子显微镜观察、X射线能谱分析以及汽轮机调速系统过热点排查,确认黑色颗粒物是抗燃油长期在局部过热环境下所生成的焦炭。对此提出防范措施:①加强滤油,及时除去油中的碳化产物及杂质颗粒;②尽快隔离并消除热源,从源头上消除抗燃油因局部过热再次发生碳化的隐患。
Black particles are observed in the fire-resistant oil of Unit 2 in a power plant. Even after the oil treatment with the fire-resistant oil treatment equipments, the black particles still come up occasionally. Through the analysis by SEM, X-Ray energy spectrum and overheat spot searching in turbine regulating system, the black particles are determined to be the coke generated from the fire-resistant oil under the local long-term overheating environment. Therefore, preventive measures are put forward, such as enhancing oil filtering, to remove the carbides and impurity particles from the oil in time, isolating and removing the overheat spots as soon as possible to eradicate the root canse of any potential carbonization from local overheating.
