WIND-DRIVEN ELECTRIC PLANT Russian patent published in 1998 - IPC

FIELD: power engineering; conversion of wind energy into electric or other energy. SUBSTANCE: wind-driven power plant has power set installed in support and consisting of at least one turbine with nozzle assembly mechanically coupled with generator, central envelope, ring front envelope with at least one turbine inlet channel forming turbine outlet channel together with central envelope, and ring outer envelope forming, together with central envelope, diffuser outlet channel. Power plant has additional ring envelope forming, together with outer surfaces of front and central envelopes, narrowing-widening first intermediate channel communicating, in its intermediate part, with turbine outlet channel. Ring envelope forms, with inner surface of outer envelope, second intermediate channel communicating, together with first intermediate channel, with diffuser outlet channel. EFFECT: increased efficiency of known plants owing to step-by-step conversion of energy of air flows. 14 cl, 7 dwg
