Abstract: A flywheel system includes a fixture providing a base and a stator, rotor having a cavity to receive the stator, a generator/motor module having a plurality of permanent magnets mechanically coupled to the rotor and an active magnetic bearing module. The active magnetic bearing module includes a plurality of magnetizable elements mechanically coupled to or integrated in the rotor, and a plurality of electromagnets mechanically coupled to a shaft and configured to magnetically couple with the plurality of first magnetizable elements to actively stabilize the rotor relative to the fixture. The windings of the generator/motor module are arranged around the rotation axis of the rotor at a first distance from the rotation axis of the rotor, the electromagnets of the active magnetic bearing module are arranged around the rotation axis of the rotor at a second distance, and the first distance is greater than or equal to the second distance.

Abstract: A flywheel system includes a rotor configured to rotate about a rotation axis. The flywheel system further includes a fixture and an active magnetic bearing module for actively stabilizing the rotor relative to the fixture. The active magnetic bearing module includes a plurality of first magnetizable elements mechanically coupled to or integrated in the rotor, and a plurality of electromagnets mechanically coupled to the fixture and configured to magnetically couple with the plurality of first magnetizable elements to actively stabilize the rotor relative to the fixture. Each of the first magnetizable elements is farther than each of the electromagnets from the rotation axis.

Abstract: The invention relates to a flue gas conditioning device (1) comprising an inlet (2), a diffuser (3) in extension of the inlet, and an essentially cylindrical pipe area (4) in extension of the diffuser, said pipe area being equipped with a bottom (5) and an outlet (6) opposite the diffuser, said diffuser and said cylindrical pipe area defining a conditioning chamber, means being provided in an area of the conditioning chamber near the inlet to introduce conditioning water into the flue gas, wherein means (10) are provided in the device to impart a rotating momentum to the flue gas stream, and means (10) are also provided to impart to the rotating flue gas stream a momentum in the axial direction. This may e.g. be realized by the provision of guide blades (11) which extend radially in the inlet.
