Abstract
The invention concerns an energy converter, comprising a boiler, a turbine (11), a condenser, a feed pump (16) and a generator (17) and, if required, a recuperator and a pre-feeding pump. The thermal energy to be supplied to the boiler has been arranged to maintain a Rankine process driving the generator (17) and thus to produce electricity. The turbine (11), the generator (17) and the feed pump (16) have a joint rotor shaft (36). The rotor (36) is rotatably carried with gas-dynamic bearings (24) utilizing the circulating fluid's vapor. The lower surface of the rotor (21) of the turbine (11) has been disposed to serve as one abutment surface of a gas-static thrust bearing (22). The gas-dynamic bearings (24) are bearings of tilting pad type.
