| 摘 要： | 空气在凝汽器内积聚可以从传热和空气分压力两个方面对凝汽器真空造成双重影响。对凝汽器建立数学模型。具体实例仿真计算表明,随着空气浓度的变化,在不同的空气浓度阶段,两种影响因素对凝汽器压力具有不同的作用程度。

| Abstract: | The abnormality of gas tightness of steam turbine vacuum system or the insufficient output of air extractor can cause air accumulate in condenser.It has dual influence to condenser vacuum from the heat transmission and the air pressure component.According to the mathematic model of condenser and the simulation calculation to an example,it showed that as the air concentration varying the two influencing factors had different effects in different air concentration on condenser pressure. |
