考虑凝结水过冷度影响的最佳真空确定方法

凝汽器真空是汽轮机运行中的重要参数，其数值大小对汽轮机的运行安全、经济性和调节性能都有很大的影响。虽然提高凝汽器的真空可以使汽轮机的理想焓降增大，电功率增加，但无论是从设计角度还是从运行角度来看，都不是真空越高越好。考虑到由于真空变化而引起的凝结水过冷对最佳真空的影响，提出了一种新的最佳真空确定方法。

The best Method to Determine Vacuum after Consider the Condensate Depression Impact

That the vacuum of a condenser is one of the important factors when the steam turbine is running.And it affects a lot towards the running safety,economy and regulatory.Though improving the vacuum of a condenser would increase the ideal enthalpy drop and electric power,it is not the higher the better whether from the design point of view or from a running point of view.In this paper,we have considered the influences of condensate subcooling degree on the optimum vacuum because of the vacuum changes.Then a ne...
