From the viewpoint of energy saving and the development of new energy resources,it is important to utilize water-dominated geothermal resources and waste-heat sources from factories. As systems utilizing such resources,steam flashing systems,binary-fluid systems,and total flow turbine systems are considered for power generation. In this study,thermodynamic consideration on such systems as single and double total flow turbine systems(1TS,2TS)is made under the condition of saturated hot water at the inlet of the systems,compared with single flash turbine systems(1FS). First,the available energy of 1TS and 2TS is explained graphically on a T-S diagram,and an optimum intermediate temperature in 2TS,which maximizes the system efficiency,is given. Second,the suoeriority of total flow system efficiency to that of 1FS is clarified and the magnitude of the improvement is estimated. Furthemore,the effects of each factor on the cycle performance of 1TS and 2TS are shown.
