STEAM TURBINE Russian patent published in 2014 - IPC F01K7/18 F01D11/06 F01K17/06 

FIELD: machine building.

SUBSTANCE: steam turbine comprises the first casing containing the first turbine, functionally connected with the rotating shaft and capable to operate at the first temperature. The end seal is intended for partial sealing of the first casing with the rotating shaft. The regulator of the steam passing through sealing is intended for intake of the steam from the end seal. The second casing contains the second turbine, functionally connected with the rotating shaft and capable to operate at the second temperature, which is less than the first temperature. The ejector is intended for preparation of a mix from at least part of the steam flow incoming from the named regulator, and steam bled from the upstream camera of pre-set stage of the second turbine, and for inflow of the named mix into the second turbine.

EFFECT: invention allows to use usefully the steam leak from seals of the high-temperature part of the turbine with the temperature which is high for the low temperature part of the turbine, and with reduced pressure, for operation in the low temperature part of the turbine.
