| Abstract: | Through the thermal tests,by using enthalpy drop method and calculation expressions,the paper carried out the quantitative calculation of shaft gland steam leakage of high back pressure units for the Heat and Power Facilities Department of Baling company and compared with the designed value.The comparison showed that the calculation results were comparatively rational,so as to solve the problem that it was difficult to determine the shaft gland steam leakage of the units as a result of complicated system and incomplete measuring points for long time. |
