<p>PROBLEM TO BE SOLVED: To provide a turbine for wive power generation capable of reducing manufacturing and installation costs by simplifying a turbine structure and a flow channel structure of airflow, superior in maintenance performance and safety, and improved in turbine operability.SOLUTION: A turbine 25 for wave power generation, driving a generator of a wave power generation device 10, includes a hollow disc-shaped partition assembly 40 disposed on an apex of a cylindrical floating body, allowing an air chamber 18 formed on an oscillating water column to communicate with the outside air in the floating body, and accommodated in a turbine casing 35, a nozzle ring assembly 43 disposed at an outer peripheral side in the partition assembly 40 as a stationary vane, an impeller 27 disposed in opposition to an inner peripheral side of the nozzle ring assembly and rotated and driven by the blown-out airflow, and an airflow control mechanism 39 for allowing the airflow from the outside air and the airflow from the air chamber 18 to be selectively switched to flow to an outer peripheral portion of the nozzle ring assembly 43. The airflow flowing to the outer peripheral portion of the partition assembly 40 is guided as inward flow in one direction through the nozzle ring assembly and the impeller.</p> |
