摘　　要：针对单缸湿汽轮机除湿级的热力计算问题,级除湿过程近似于等熵过程,在级热力计算的基础上提出了一种除湿级的热力参数计算方法,以某型单缸湿汽轮机为例进行了计算。结果表明,除湿后蒸汽的焓值和干度明显增高,蒸汽的做功能力也增大。For questions of the thermodynamic calculation of single cylinder wet steam turbine, approximated the dehumidification process as isentropic process,on the basis of the stage＇ s thermodynamic calculation method, proposed a thermodynamic calculation method of the Removing-humidity Stage, and use a single cylinder wet steam turbine as an example for contrast calculation. The results show that dehumidified steam enthalpy and dryness increased significantly, steam ＇ s power increased too.
