摘要

PROBLEM TO BE SOLVED: To provide a turbine component capable of reducing mixture loss to improve performance of an existing turbine plant.;SOLUTION: A turbine component 11 is attached to a rear edge end surface of a shroud 6, wherein the shroud is provided at a tip of a rotor blade 5. The turbine component has a surface facing a main flow passage and a surface facing a clearance flow passage, in a case of being attached to the rear edge end surface of the shroud 6, and is formed so as to make the surface facing the clearance flow passage closer to the main flow passage toward a downstream side in a view from a cross section cut on a plane containing a turbine central axis O.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
