HIGH-SPEED STEAM TURBINE Russian patent published in 1994 - IPC

FIELD: heat power engineering. SUBSTANCE: turbine has fixed casing 1 with radial supply of life steam. Casing is provided with steam distribution passage terminating in steam dispersing nozzle 7. Rotor is provided with shroud 6 of blades 11, steam supply ports 23 arranged over periphery of the rotor end walls and axial passages for bleeding the steam. Arranged in these passages in the area of rotor lateral walls are additional blades. Rotor is mounted in the casing in such a position that it forms helical centripetal passage between partition 10 and outer surface of the rotor shroud. This passage is brought in communication with passage of the casing by means of nozzle 7. In the area of outlet of rotor axial passages there is waste steam discharge passage. EFFECT: enhanced efficiency. 2 cl, 6 dwg
