Final FW Temp. Decreases by About 0.8 F
HP, LP Turbine Bowl, Stage & Extrn. Steam Pressures Decrease By About 1%
TTD’s, DCA’s in Both Strings Decrease By About Same Amount (0.1 to 0.2 F)
Capacity Loss is About 7 Mwe (0.8%)
Impact of 1% Reduction in FW Flow
Detailed Model Permits Predicting Changes in Capacity & Impact Upon Various Parameters Facilitates Conducting Diagnostics
& Confirming As Well As Validating Predicted Changes
Conclusions & Recommendations
