| Abstract: | Based on ASME PTC6 Turbine Performance Acceptance Test Code,the principle of calculating the specific enthalpy of exhaust steam from low-pressure(LP) cylinder has been determined.and four processing methods for condition curves in calculation of specific enthalpy for exhaustc steam from LP cylinder at home and abroad being presented,and the advantages and disadvantages of each method being analysed.Directing against one concrete unit type,the calculated results of four processing methods have been given,and recommendations for concrete application of each processing method in practical test and calculation being put forward. |
