<p>PROBLEM TO BE SOLVED: To provide a helium gas turbine power generating system in which a pressure vessel can be reduced in size. SOLUTION: The turbine power generating system comprises a pressure vessel (3) internally circulating gas, a gas furnace (1) for heating the gas, a turbine (4) disposed in the pressure vessel (3) and rotated by the gas, a generator (7) coupled with the turbine (4) through the rotary shaft (6) thereof and disposed on the outside of the pressure vessel (3), and a shaft sealing device (8) disposed at a part where the rotary shaft (6) penetrates the pressure vessel (3) such that the rotary shaft (6) can rotate and preventing the gas from leaking through the penetrating part to the outside of the pressure vessel (3).</p> |
