    Invention m. used in power plants with boiler, turbine (T), condenser, feed pump (PN) and generator. EFFECT: higher efficiency. T 2 radial-type power converter with a rotor (P) 13, a generator and PN 6 are placed on a common P 12. P 12 is installed vertically in a single housing 14 by means of radial bearings 15, made of gas-dynamic. Last m. performed segmental. The generator is located between T 2 and MON 6. The working medium vapor expands in T 2. In this case, part of the fresh steam is supplied through the chamber 16, made in the upper part of the housing 14, under the lower surface 17 P 13 of the turbine 2, where a supporting gas film is created that allows reduce wear. 1 hp f-ly, 2 yl. i SU) with 4 :; About SP O 00 5 sleep

    专利说明:

    The invention relates to the field of energy, namely to energy converters, for example, to power plants with a boiler, a turbine, a condenser, a feed pump, a generator and, if necessary, a heat exchanger and a pre-feed pump.
    The purpose of the inventions is to increase economy.
    FIG. 1 shows the circulation circuit of an energy converter; in fig. 2 - the central part of the energy converter with a cross section of the turbine, generator and feed pump.
    The circulation circuit of the energy converter (Fig. 1) contains the boiler 1, the turbine 2, the heat exchanger 3, the condenser 4 with the system 5 of circulation water or air cooling, the feed pump 6. The circulation circuit of the converter may also contain a pump 7 of the preliminary supply, generator 8, common circuit 9 and stabilizer 10 with circuit 11 electrical consumer.
    The turbine 2, the generator 8 and the feed pump 6 have a common rotor 12.
    The turbine 2 of the energy converter (Fig. 2), for example, of the radial type with the rotor 13, the generator 8 and the feed pump 6 are placed on a common rotor 12 mounted vertically in a single housing 14 by means of radial bearings 15, made gas-dynamic, and in a turbine, for example, segment type generator 8 is located between the turbine 2 and the feed pump 6, in the upper part of the housing 14 is made of the camera 16 for supplying fresh steam under the bottom surface 17 of the rotor 13 of the turbine 2.
    A feed pump 6, for example a single-stage turbopump, with a contactless seal, is communicated by means of a chamber 18 of bore holes and a drainage pipe 19 to a condenser 4.
    In the contour of the Converter (figure 2) it is possible to accommodate the check valve

    19 between the boiler 1 and the turbine 2 and the valve 20 between the heat exchanger 3 and the boiler 1.
    The energy converter operates as follows.
    The working medium is evaporated using heat supplied to boiler 1, enters turbine 2, where it expands, cools in recuperator 3 and condenses in condenser, giving off part of the heat supplied to the medium (air or water) circulating through system 5.
    The pre-feed pump 7 and the feed pump 6 return the working medium condensate directly to the boiler 1 or through the heat exchanger 3.
    An expansion of the vapor of the working medium takes place in the radial turbine 2, with a part of the fresh steam being supplied through the chamber 16 under the bottom surface 17 of the rotor 13 of the turbine 2, where a supporting gas film is created, which allows reducing wear and increasing efficiency.
