  • INTEGRATED HERMETICALLY SEALED TURBOEXPANDER-GENERATOR WITH AN ELECTRIC GENERATOR AT AN END OF A COMMON SHAFT LINE
    Publication number: 20230332508
    Abstract: An integrated hermetically sealed turboexpander-generator comprises a hermetically sealed casing arrangement, a turboexpander, a compressor and an electric generator, arranged in the hermetically sealed casing arrangement along a common shaft line, supported by active magnetic bearings. Also disclosed is a thermodynamic system using the integrated hermetically sealed turboexpander-generator to convert waste heat from a waste heat source into electric power. The electric generator is arranged at one end of the common shaft line.

  • Radial—axial turboexpander
    Patent number: 11149587
    Abstract: The combined radial-axial turboexpander (1) comprises a casing (3) and a shaft (5) arranged in the casing (3) for rotation therein. A radial impeller (25) and an axial expansion wheel (43) are mounted on the shaft (5). The axial expansion wheel (43) is arranged downstream of the radial impeller (25). A working fluid expands sequentially in the radial impeller and in the axial expansion wheel.

  • Multi-stage radial turboexpander
    Patent number: 10927756
    Abstract: A multi-stage turboexpander and a method for generating mechanical power therewith are disclosed. The multi-stage turboexpander includes a casing and a shaft, arranged for rotation in the casing. The shaft is supported by a first bearing at a first shaft end portion and a second bearing at a second shaft end portion. A first radial impeller and a second radial impeller are arranged between the first bearing and the second bearing on the shaft for co-rotation therewith around a rotation axis.
