Abstract

Abstract: In the seal oil system of steam turbine No.2 in Hunan Huadian Changsha Power Generation Corporation Limited, the hydrogen purity was less than the standard, the vacuum of the seal oil vacuous tank was below the standard, and there were many bubbles in the oil of the seal oil vacuous tank. Aiming at the problems listed above, the abnormal situation occurred in the seal oil system of the unit No.2 was analyzed, and relevant treatment measures were adopted.

Key words: steam turbine, seal oil system, hydrogen purity, vacuum, treatment
