Title:
REACTION-TYPE STEAM TURBINE
Document Type and Number:
WIPO Patent Application WO/2017/010671
Kind Code:
A1
Abstract:
The present invention relates to a steam turbine reducing unnecessary axial force, which can be applied to a turbine shaft transmitting the rotational driving force of a plurality of nozzle rotating bodies connected in multiple stages, and capable of preventing an operation fluid discharged from each nozzle rotating body from functioning as a resistor of the nozzle rotating bodies, wherein the steam turbine comprises: a housing (110); the turbine shaft (120) rotatably supported in the housing (110); a plurality of disc-shaped nozzle rotating bodies (130) integrally coupled to the turbine shaft (120), having at least one nozzle hole (132) such that the nozzle rotating bodies rotate while the operation fluid is jetted through the nozzle holes, and stacked along the axial direction of the turbine shaft (120); and a guide panel (140) positioned at the rear end of the nozzle rotating body (130) in the flow direction of the operation fluid and fixed to the housing (110) so as to guide the flow of the operation fluid.
