摘　　要：在压水堆核电机组汽水分离再热器(MSR)的实际运行工况下验证饱和湿蒸汽通过波形板分离元件时的分离特性和压降特性。采用大型热工-水力试验台架提供满足要求的饱和湿蒸汽,获得该湿蒸汽流经试验件的压降和残余湿度,结果表明:该MSR波形板试验件的二次携带临界流速较高,在入口蒸汽干度不大于86%且入口速度低于临界流速时,其残余湿度不大于0.1%,分离效率在99%以上,压降不大于7k Pa,满足出口蒸汽干度不小于99%、分离模型压降不大于14 kPa的设计要求,具有良好的分离和压降特性。The separation characteristics and pressure drop characteristics of the saturated wet steam through the corrugated plate separation element are verified under the actual operating conditions of the moisture separator reheater(MSR)for PWR nuclear power units.The saturated wet steam which meets the requirements are provided by using a large thermal hydraulic test bench,and the pressure drop and residual humidity are obtained when the wet steam flows through the test piece.The results show that the critical flow rate of re-entrainment is high,and when the inlet steam dryness is not greater than 86%and the inlet flowrate is less than the critical flowrate,the residual humidity is not greater than 0.1%,the separation efficiency is of 99%or more,and the pressure drop is not greater than 7 kPa.The design requirements of more than 99%steam dryness and less than 14 kPa pressure drop are satisfied.It is with good separation and pressure drop characteristics.
