Geothermal fluids, which operate steam turbines in geothermal power stations, generally contain several percent of noncondensable gases. The presence of such noncondensable gases in the steam affects the performance of a steam turbine significantly. To clarify this effect, thermodynamic analytical treatment is presented. Coordinated field and laboratory test programs, including idealized element tests and an overall performance test in a model turbine, have been carried out and substantial agreement with analytical predictions has been achieved. This method has been utilized successfully in the design of geothermal turbines, which will contribute to a significant improvement of geothermal energy utilization.
