Abstract: Vacuum degree of exhaust steam device of N300-16.7/537/537 type steam turbine used in Xinfeng Power Plant in
Inner Mongolia is lower than the design value for a long time, which had serious influence on the economy and safety of steam
turbine, and still could make the unit cannot reach the full rated output in summer. Through the analysis and research, this paper
found out the reasons, and put forward methods to improve the vacuum degree of exhaust steam device. Key words: steam turbine; low vacuum degree; analysis; methods
