Turbine performance results which have been reported at an engineering conference indicate significant differences between the turbine vacuum corrections obtained from plant tests and those supplied by the turbine vendor. In the vicinity of the design vacuum considerably lower or higher than the design levels the differences are significant. Anomalies were observed (by one of the authors) in vacuum corrections during cycle studies conducted in 1970 and 1975. Subsequent analysis of the data revealed that the assumptions used in determining the boiler feed pump/boiler feed pump turbine, BP/BFPT, performance were responsible for the anomalies. If the field data are not corrected for deviations from the heat balance BFP/BFPT and feedwater heater operating assumptions, it will result in deviations between the tested and predicted vacuum corrections.
