Abstract

PURPOSE: To efficiently cool the moving vane of a turbine which is provided with a coolant passage under the surface, by separating a liquid coolant from vapor produced in the passage and by causing the vapor to go out through small holes opened in the surface of the vane.
CONSTITUTION: To cool the moving vane of a turbine, a coolant 11 flows from a reservoir 12 at the mounted bottom of the vane and overflows a weir 13 and enters into a main coolant passage 2. The coolant flows due to a thermosiphon effect as shown by an arrow 14 and moves from a coolant passage 3 at the tip of the vane to another coolant passage 4 under the surface of the vane. The coolant 11 enters into a reservoir 5 after cooling the vane. The coolant 11 then flows into the main passage 2 again through a goove 6 and repeats the above-mentioned process of flow. In the process, vapor produced in the cooling coolant passage 4 is separated from the liquid coolant in the reservoir 5 and then flows into a vapor passage 7 through a weir 8 and enters into a main high-temperature gas flow through numerous small holes 9 in the surface of the vane to keep the heat of high-temperature gas from coming into the moving vane.
