Patent ID: 11280323

Abstract:
A geothermal energy system utilizes supercritical CO2 turbine and a radial outflow reaction turbine, a Catherine Wheel having wheel arms, that spins around an axle to produce power. A fin portion extends from the radial portion at an offset angle, to an exhaust end. A first working fluid, such as supercritical carbon dioxide flows through an arm conduit within the wheel arm and a second working fluid, such as a hydrocarbon mixes with the first working fluid and both flow through a turbine. The turbine may be configured within the wheel arm conduit or mounted prior to the Catherine Wheel or any other radial outflow reaction turbine, or variable phase turbines available, and it turns as the combined working fluids expand and vaporize. The second working fluid may be condensed and recirculated while the first working fluid is expelled back into a geothermal reservoir.
