Abstract

PURPOSE:To make it possible to generate electrical power with the use of air turbines arranged in positions remote from a penstock, by providing projecting parts at several positions in the inner surface of the penstock in the intermediate position thereof so that Venturi action is utilized for reducing pressure in air turbine chambers. CONSTITUTION:Venturi action is brought about by water flow 11 through a hydroelectric generating penstock 1 having a narrow part formed by providing a projecting part 2 on the inner surface of the penstock 1 so that air in pipes 4, 5 and a low pressure tank 8 is sucked for reducing pressure therein. Accordingly, differential pressure between them and the atmospheric air is produced across an air turbine, and therefore, air from an atmospheric air introducing port 9 establishes air stream in the direction of arrow 12, which is blown to an impeller in the air turbine 6 for electrical generation. By the provision of a plurality of narrow parts as above-mentioned, a plurality of air turbines 7 may be utilized for electrical generation, and further, the electrical generation may be carried out by the turbines which are remote from the penstock, since air blast is used for the electrical generation.
