FIELD: machine building.
SUBSTANCE: restricting assembly is located around the shaft. The first pipe is connected as to fluid medium with the restricting assembly. The first pipe has the possibility of supplying the flow of low-temperature steam of low pressure to the restricting assembly. The second pipe is also connected as to fluid medium to the restricting assembly downstream of the first turbine section and upstream of the first pipe. The second pipe receives some part of high-temperature steam of high pressure passing to the restricting assembly from the first section of turbine. A valve is connected as to fluid medium to the second pipe. The valve has the possibility of selective activation to provide mixing of high-temperature steam of high pressure with low-temperature steam of low pressure in the second pipe.
EFFECT: increasing operating efficiency of a steam turbine.
