Claims

[Scope of utility model registration request]

An annular exhaust passage formed on the exit side of the final stage rotor blade of the axial flow turbine is divided into a plurality of exhaust passages by a plurality of vanes extending in the radial direction of the annular exhaust passage, and the exhaust inlet side of each vane is divided into a plurality of exhaust passages. The end of each vane is aligned with the exhaust flow direction from the final stage rotor blade, the end of each vane on the exhaust outlet side is located parallel to the turbine axis of the axial flow turbine, and each vane is aligned with the exhaust inlet. The exhaust flow path is curved smoothly from the side end toward the exhaust outlet side, and the lateral cross-sectional area of each exhaust flow path is gradually increased from the exhaust inlet side to the exhaust outlet side. Characteristics of the axial flow turbine exhaust diff user.
