摘要

PURPOSE: To diminish or eliminate the known bearing problems in a power recovery plant comprising a gas turbine with a turbine wheel and a generator with a rotor driven by the turbine wheel. CONSTITUTION: A turbine 12 and a generator 14 are combined in a plant housing 10 to from one unit. A turbine wheel 22 and a rotor 30 form a rotor unit 26 rotating as a whole. The rotor unit 26 is rotatably mounted in the plant housing by magnetic bearing units 34, 36 in a non-contact manner.
