The development of the 100kW radial steam turbine power generation system with the small flowing-through boiler was introduced. The 250,000 units of the small flowing-through boilers of which heat transfer area is less than 10m^2 are distributed in Japan. Now, these boilers are used just as heat source. By adding a steam turbine to these boilers, the system is used not only as heat source but also as power supply. The radial turbine which is preferable compared with an axial turbine under the small pressure ratio condition is selected, because the pressure of these boilers is limited below 1MPa by Japanese laws. In this paper, for discussion the potential of this system, the simple system analysis has been carried out under the ideal condition. The results show that the re-powering efficiency is quite good and the system have a good potential of energy conservation.
