Lubricating oil system is an important auxiliary system of thermal power unit. The equipment and pipes in the system may have foreign impurities in the process of manufacture, transportation and installation. In order to discharge foreign impurities from the system, it is particularly important to flush the lubricating oil before the unit is officially operated to ensure that the key components such as bearing bush, journal, are not damaged and affected in operation. This paper combines the optimization of the original flushing scheme of the lubricating oil system of a 1000MW unit in China, and introduces the optimized flushing methods and measures. By introducing the establishment of good working practice and experience feedback, it facilitates the follow-up similar work, and also provides a good guarantee for the safe and reliable operation of the unit, and brings good economic benefits.
