It is important to utilize water-dominated geothermal resources and waste heat sources from factories from the viewpoint of energy saving. The cycle performance of single and double total flow turbine systems(1TS,2TS) and a single flash turbine system(1FS)is analyzed under the condition of wet steam at the inlet of the systems in a way similar to that described in the 1st report. First,the avaiable energy of the systems is expressed on a T-s diagram,and an optimum intermediate temperature which maximizes the system efficiency of 2TS,1FS,is clarified. Second,the efficiency of the two-phase flow turbine required for 1TS to achieve the system efficiency higher than 1FS is shown and an increase of the system efficiency of 2TS over 1FS is estimated. Moreover,the effects of factors such as inlet pressures and temperatures on the cycle performance of 2TS are shown.
