<p>A coaxial duplex turbine in which a Wales' turbine is provided on the inner peripheral side, a first annular fluid flow is formed for rotating said Wales' turbine, and a second fluid flow is formed radially outside the first flow so as to rotate another turbine provided on the outer peripheral side. At the time of startup, a turbine on the outer peripheral side starts rotating first, the output of this turbine actuates the compressor, and an accelerated and compressed fluid is fed into the hollow turbine blades of said Wales' turbine and then discharged through a passage bent to the side of the trailing edge in a blade. Such structure intends to improve self-starting function and energy conversion efficiency of the Wales' turbine. The apparatus of this invention is principally used for a wave activated power generator. <IMAGE></p> |
