CLOSED LOOP STEAM TURBINE ENGINE SYSTEM Russian patent published in 2025 - IPC F01K11/00 F01K13/00 F01B23/08 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of machine building, in particular to steam engines operating on heated air/gas, which can be used as replacement of electric motors for drive of various machines and mechanisms of stationary arrangement. Closed-loop steam turbine engine system includes steam turbine engine 1 consisting of turbine 2 and reduction gear 3 interconnected by main gear 4. Reduction gear 3 comprises a housing and a rotation transmission mechanism with an output shaft, where reduction gear 3 has an oil circuit of pipeline 5 extending from the bottom of the housing of reduction gear 3 and entering from the top of the housing of reduction gear 3, wherein cooler 6 is arranged on the path of oil circuit of pipeline 5 to cool down oil filled in housing of reduction gear 3. Air compressor 8 is connected to reduction gear 3, wherein air compressor 8 is configured to create pressure inside housing of reduction gear 3 for oil circulation along oil circuit of pipeline 5. Outlet of turbine 2 is connected to inlet of condenser 9, containing cooling unit 10 with inlet and outlet of cooling heat carrier, condensate collection unit 11 is connected to vacuum pump 12. Condenser 9 outlet is connected along pipeline circuit to inlet of spiral heat exchanger 13 of superheater 14, wherein said pipeline comprises water pump 15 to pump working medium, at least one pressure gauge 16 and control shut-off valve 17. Superheater 14 includes spiral heat exchanger 13, as well as heating boiler 18, where heating boiler 18 is made with possibility of interaction with spiral heat exchanger 13 for superheating of working medium to steam condition. Outlet of spiral heat exchanger 13 is connected to inlet of turbine 2 for transfer of working medium heated to working temperature to turbine 2 and implementation of operation of steam turbine engine 1 with transmission of rotation from turbine 2 to output shaft of reduction gear 3 through main gear 4.

EFFECT: simplification of the steam turbine engine system; increasing the efficiency of the system.
