Abstract

The impeller is preferably modified to use back swept, radial or forward swept blades to accommodate relatively low, medium and high lift, respectively applications for both centrifugal compressor and turbine rotor use.

       7 . An organic rankine cycle system of the type having in serial flow relationship a pump, an evaporator, a turbine and a condenser, wherein said turbine comprises: 
 an arcuately disposed volute for receiving an organic refrigerant vapor medium from the evaporator and for conducting the flow of said vapor radially inwardly;    a plurality of nozzles circumferentially spaced and disposed around the inner periphery of said volute for receiving a flow of vapor therefrom and conducting it radially inwardly; and    an impeller disposed radially within said nozzles such that the radial inflow of vapor from said nozzles impinges on the plurality of circumferentially spaced blades on said impeller to cause rotation of said impeller; and    discharge flow means for conducting the flow of vapor from said turbine to the condenser;    wherein, said impeller blades are either back swept or forward swept.
