Euler Turbine

The Euler Turbine is a patented high efficiency turbine. The turbine is the basis of the Microsteam® Turbine and has been applied to power generation from geothermal resources.


The cutaway shows an Euler Turbine developed for a geothermal project in Germany. The turbine operates with an ammonia-steam mixture in a Kalina Cycle to produce nearly 600 kW. The unit features a center inlet and radial outflow fluid path. The robust blisk geometry with two-dimensional blades results in a low cost, erosion resistant design. Its high efficiency and competitive pricing led Siemens AG to select the Euler Turbine for their project over European competitors.


Please refer to our technical paper for a more detailed description of the technology and its application to geothermal power production in a Kalina cycle.
