HIGH-TEMPERATURE STEAM POWER PLANT Russian patent published in 2020 - IPC F01K23/08 F01K25/02 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering and is intended for electric power generation. High-temperature steam power plant includes furnace boiler with steam superheater, steam turbine, condenser, feed pump, circulation circuit of liquid heat carrier with low pressure of saturated vapors, including high-temperature heat exchanger of furnace boiler, pump, high-temperature steam superheater comprising steam inlet and outlet, liquid heat carrier inlet and outlet, hydraulic turbine connected to pump via hydraulic clutch with controlled torque. Thus, the steam from the steam superheater enters the high-temperature steam superheater inlet, is overheated to high temperature, enters the high-temperature steam superheater output and the steam turbine connected to the electric generator for conversion into electric energy. At that, for control of liquid heat carrier pressure in high-temperature steam superheater and use of energy of hydraulic turbine for operation of pump hydraulic coupling is used.

EFFECT: invention allows increasing the high-pressure superheated steam temperature due to the liquid heat carrier pressure increase in the high-temperature steam superheater up to the value closest to the superheated steam pressure and using the hydraulic turbine energy for the pump drive, having increased efficiency of the heat power plant as a whole.
