摘要： PROBLEM TO BE SOLVED: To provide a mixed medium power generating system capable of increasing turbine output and generating power with high efficiency by lowering back pressure of a mixed medium turbine to increase the turbine output. SOLUTION: A mixing and absorbing means used for mixing high concentration mixed medium steam with low concentration mixed medium liquid and absorbing the same is formed by connecting in series a first stage mixing and absorbing means and a second stage mixing and absorbing means. Thus, mixed medium liquid is injected from each driving nozzle at high speed into each main nozzle, whereby suction effect in each sucking part is serially cumulated and applied, so that the back pressure at an outlet of the mixed medium turbine is held down to the lowest, and the output can be increased. An intermediate return liquid returned in the second suction part is taken out, whereby heat generation caused at the time of mixing and absorbing is restrained to lower the back pressure.
