Abstract
PURPOSE:To cool effectively the rotary blade of a gas turbine without loss of efficiency of the turbine, by making water used as cooling fluid not to mix in the flow of working gas by letting the water flow in the rotary blade through a closed loop. CONSTITUTION:Two chambers are arranged in a case 3, concave guide vanes 4 are arranged in one of the chambers and convex guide vanes 5 are arranged in the other. On the other hand, the cooling fluid passage 8 provided with fluid inflow and outflow openings 9, 10 is arranged in a rotary blade 1 and the inflow opening 9 and the chamber including the guide vanes 4 are connected through an outflow passage 11 and a pipe 13, and the outflow opening 10 and the chamber including guide vanes 5 are connected through a recovering passage 12 and a pipe 14. Water used as cooling fluid flows in the case 3 from a pipe 15. Then, its pressure is raised by the guide vanes 4, and the pressurized water running through the outflow passage 11, the pipe 13 and the inflow opening 9 flows through the passage 8, and after cooling a rotary blade 1, the water flows through th outflow passage 10, the pipe 14, and the recovering passage 12. Then, its pressure is raised by the guide vanes 5 and exhausted from a pipe 16. Thereby, as cooling fluid flows through a closed loop, the efficiency of a turbine is not lowered.
