the qualitative and quantitative relationship between the vacuum tightness and the leaking air flow rate into condenser of 300 MW units made in home has been obtained.Based on the conversion relation of volume flow of exhaut steam from the low-pressure casing of units with different output capacities
the quantitative evaluation criterion of vacuum tightness has been given.From results of the test study
a judgement basis can be provided for evaluating the influence degree of in-leaking air upon the performance of condenser in daily operation of turbo-generator set.
