In view of growing needs for the effective recovery of steam energy, which might be otherwise wasted because of its low temperature, low pressure and so on, one of the reliable and promising choices is the introduction of small, distributed steam power generation systems. In particular, high-efficiency small steam turbines in the power range of less than 1MW are effective for the above usage, such as the on-site introduction to where the surplus or that low-grade steam exists. In this paper, the 100kW radial steam turbine system with 2t/h-class once-through boilers and steam heaters will be presented focusing on its system concept, design features and an operational result. And at the pressure of 0.75MPa and temperature of 216℃, the steam turbine power generation system was operated in order to investigate the total system efficiencies and performances. And the turbine efficiency at the output shaft was calculated to be 84%, and it was higher than what were previously reported.
