A turbine generator 100 comprising a shaft 110 mounted to rotate about an axis 99, and two or more turbine wheels 120 130, which are rotatably driven by separate fluid flows. The turbine wheels are coupled to the shaft 110 such that the rotation of the turbine wheels rotates the shaft 110 about its axis 99. The turbine generator further comprising an electrical generator 140 having a rotor 141 and a stator 142, the shaft 110 being coupled to the rotor 141 such that the rotation of the shaft rotates the rotor relative to the stator to generate electricity. The separate fluid flows that drive the turbine wheels may be from the exhaust gas from an internal combustion engine 10 and/or from a flow of working fluid of a waste heat recovery system 150 of an engine system. The use of two turbine wheels driven by separate fluid flows to power a single generator allows for a less complex and more compact overall design. |
