Customized ORC micro turbo-expanders - From 1D design to modularconstruction kit and prospects of additive manufacturing
Original language description
Due to the various ORC applications, it is not expedient to design and build one standard turbogenerator.Therefore, authors developed aflexible“micro-turbine-generator-construction-kit (MTG-c-kit)”bymeans of which a customized turbogenerator can be made for any required power output between 1 and200 kW, for a wide range of workingfluids and boundary conditionsequickly, cost effectively and withhigh expander efficiency. The architecture and main features of this kit are briefly introduced.However, more focus is put on the developed 1D turbine design tool. It allows to quickly design andoptimize a single stage turbine for anyfluid and boundary conditions. The implemented models arepresented on two specific design examples - an axial impulse and a radial inflow cantilever turbine. Also,the experimental results of the two micro turbines designed and built according to this approach, arepresented and discussed.Focusing to further accelerate and cheapen the customized micro-turbogenerators for low tempera-ture applications, we provide an outlook of possibilities of additive manufacturing methods like 3Dprinting of turbine nozzles and rotors. These new possibilities provide potential to improve the com-petiveness of small-scale ORC. A simple air turbine design with plastic and metal components has beenmanufactured and tested.
