Abstract:

There was an incident that a gas power generation company control oil turned black, electrical resistivity and acid value over standard and other degradation phenomenon, and affected operational safety and stability of control oil system component. After excluding overheat, inner inspection of control oil tank was carried. Partial circulating ratio abnormal high is the main reason caused oil quality degradation. The improvement of providing tank baffle was introduced.

Key words:

control oil, black oil, electrical resistivity, acid value, circulation ratio, fuel tank baffle
