[Also in Division F2] In a thermal power plant a gas, e.g. helium, is compressed, heated in a reactor and expanded in a turbine, and a portion of the gas is withdrawn from the circuit, passed through a purifier, supplied to the bearings of the compressor and turbines as a bearing gas, and lubricant, and then reintroduced into the working circuit. The compressor 1 urges the gas through the reactor 3, turbines 4 and 5 and back to the compressor 1 via the heat exchanger 2 which preheats the gas flowing into the reactor. An auxiliary circuit branches off at a point 13 of the compressor 1 and the gas is passed successively to the purifying plant 15, accumulator 20 and through branch pipes 24, 25, 26, 27 to the bearings 9, 10, 11, 12. The bearings are aerostatic with gas cushions distributed over the bearing periphery. In bearing 12 a liquid seal is provided on the side on which the turbine shaft passes to the outside. Gas cylinder 33 provide additional gas should any leakage occur.
