Abstract

Abstract: Since the two 200MW units of Zhengdong New District Thermal Power Plant were put into operation, some problems exist in turbine lube oil system, for example, the oil seems not too transparent, and the water content in the oil is out of limit. By using of the airsealing oil baffle, the bearing boxes of HP cylinder and IP cylinder of the turbine were reformed. After the reformation, the problem of higher water content in the lube oil was solved; the operation and maintenance cost was decreased greatly; the effect of the reformation is extremely significant.

Key words: lube oil, labyrinth oil baffle, air-sealing oil baffle, reformation
