The condenser must not only maintain vacuum, but also must meet strict vacuum degree requirements. The so-called “vacuum” refers to the state of negative pressure. The high temperature and high pressure steam from the steam turbine passes through the high pressure cylinder, medium pressure cylinder and low pressure cylinder and is finally discharged into the condenser. Therefore, the vacuum degree of the condenser is directly achieved. affects the smooth flow of steam and increases the power of the steam turbine. Generally, decreasing the condenser vacuum during operation will directly affect the efficiency of the steam turbine. When the vacuum reaches the specified value, the load must be immediately reduced (reduce the steam flow), otherwise it may cause overpressure in the low pressure cylinder and also pose a threat to the final blade.

Introduction Why should the condenser of a power plant maintain a vacuum? The condenser not only needs to maintain a vacuum, but also has strict requirements for the degree of vacuum. The so-called “vacuum” refers to the state of negative pressure. High temperature an
