Claim Text:
1. A multi-pressure radial turbine system comprising: a closed circuit including: a plurality of pumps for pressurizing heating media introduced therein to different pressures; a plurality of evaporators for vaporizing the heating media delivered from the pumps by absorbing heat from a first heat source; a multi-pressure radial turbine that expands the heating media having different pressures and temperatures, supplied from the evaporators, to obtain output power; and a condenser for condensing the heating medium expanded in the multi-pressure radial turbine by making the medium release heat to a second heat source having a lower temperature than the first heat source, wherein the closed circuit is a cycle circuit through which the heating medium circulates while repeatedly changing its state between vapor and liquid, and wherein the multi-pressure radial turbine includes a turbine wheel that rotates in a casing, the turbine wheel having a plurality of turbine wheel inlets from which the heating media are introduced at different pressures and one turbine wheel outlet from which the expanded heating medium is discharged in an axial direction.
