PURPOSE:To make it possible to use high temperature steam by forming moving blades in an integrated shape consisting of a passage made of heat-insulating materials and embedded and tenon parts, in the moving blades of an axial turbine. CONSTITUTION:The passage 24 of an axial turbine blade is made of heat insulating materials of low thermal condutivity and the passage 24 is integrated with tenon-8 and embedded parts 5 by welding-all-around. Thus, the temperature of the tenon-8 and embedded parts can be reduced. Consequently, the use of high temperature steam becomes possible. |
