Korea Institute of Energy Research Institute (KIER) develops three supercritical carbon dioxide power cycle (SCO2) experimental test loops: kWe, tens of kWe and hundreds of kWe class. First, a 4.5 kWe single radial-type turbogenerator with a labyrinth seal and an angular contact ball bearing was developed to operate a simple recuperated transcritical cycle. A 86 We of electric power was obtained during 30 minutes under a 320°C of turbine inlet condition. Second, a 60 kWe single stage axial…
