Abstract (en)
[origin: EP2613026A2] A power generation system (10) includes a non-azeotropic working fluid mixture and a Rankine cycle system (12). The Rankine cycle system (12) includes a turbine generator that is driven by vapor of the first working fluid mixture, and a condenser (16) that exchanges thermal energy between the vapor received from the turbine generator (14) and a cooling medium. The working fluid mixture is characterized by a condenser temperature glide during phase change between approximately five degrees and thirty degrees Kelvin, a condensing pressure between approximately one tenth of one percent and eleven percent of a critical pressure of the working fluid mixture, and a condenser bubble point temperature between approximately one degree and nine degrees Kelvin greater than a temperature at which the cooling medium is received by the condenser (16).
