FIELD: power engineering.
SUBSTANCE: method to generate energy by means of thermodynamic cycles with water vapour of high pressure and moderate temperature is carried out by means of thermodynamic cycles, in which vapour temperature during its generation is limited to moderate values, which include the following stages: generation of water vapour under pressure of more than 65 bar and moderate temperature below 400°C; expansion of the specified vapour in the steam turbine, at the same time steam is produced with intermediate pressure, which is in the range of 10-40 bar and moderate moisture, less than 15%, the specified steam is dried with the help of a moisture separator, and reheating of the specified steam is carried out, the steam is expanded in the turbine, and feedwater for the steam generator used to generate steam is heated with the help of a row of steam bleeds from the turbine taken for heat exchange with the specified feedwater for the steam generator.
EFFECT: invention makes it possible to increase energy and operating efficiency during conversion of thermal energy into mechanical or electric energy.
