J. Buongiorno / Spring 2005 22.313J, 2.59J, 10.536J THERMAL-HYDRAULICS IN POWER TECHNOLOGY Homework Set 3 Steam Separation in a PWR U-tube Steam Generators The schematic of a PWR U-tube Steam Generator (SG) is shown in Figure 1. Saturated steam at 5.7 MPa and 11% quality is generated in the U-tube bundle region. The majority of the liquid is removed in the steam separator. The residual liquid is removed in the steam dryer. The steam flow rate to the turbine is 456 kg/s. The properties of steam and water at 5.7 MPa are reported in Table 1. Steam Dryer Steam Separator Riser Steam to Turbine Feedwater Primary Water In Primary Water Out Figure 1. U-tube Steam Generator Steam Separator You are to consider a steam separator design based on gravity separation. i) Calculate the minimum height of the region above the free liquid surface that minimizes carryover. (Hint: the riser has a flow area of 7.07 m 2 , and is partitioned, so that its equivalent diameter is 0.2 m) ii) Calculate the separation efficiency of the gravity separator. (Hint: ignore the effect of
