STEAM TURBINE Russian patent published in 2020 - IPC F01D25/24 F01D1/12 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering, particularly, to low-power turbines. Steam turbine includes housing, shaft with disc with reactive working blades fixed on shaft, two rotary devices for changing direction of working medium movement, which are installed above working blades along all circumference on both sides of disc, inlet and two outlet branch pipes for supply and removal of working medium. At that, housing is made with vertical connector, jet working blades are made detachable and installed parallel to disc rotation axis so that parts of working blades interacting with working medium are located on both sides of disc, at that, on both sides of the disc there are two input inlet diaphragms forming input windows, which are arranged in front of the working blades and contain guide vanes and seals, to which the separation walls are connected, and on both sides of the disk there are two outlet openings forming outlet openings, which are arranged after the working blades and contain seals, to which separation walls are attached, and rotary apparatuses provide one-way supply of working medium to guides and working blades located parallel to axis of rotation of shaft.

EFFECT: invention provides increased turbine power, reliability and efficiency.
