摘要
影响汽轮机凝汽器真空的因素甚多。为使在设计与运行中能更好地理解和掌握调节真空的手段,对主要影响真空因素的机理进行分析,提出真空变化的计算公式,并通过具体机组的数据(引进型300MW机组)说明各主要影响真空因素单独作小量改变时真空的变化程度。
There are many factors effected the vacuum of steam turbine condenser. In order to understand how to control the vacuum, the mechanism of the principal influential factors has been analyzed and the formulas to calculate the vacuum proposed. Also, through the data of the introduced 300MW unit, the variation of vacuum is demonstrated during small change of each principal influential factor.
