Abstract:
A method of operating a Kalina cycle power generation system, comprising the steps of: directing a stream of superheated binary working fluid to a turbine; expanding the superheated binary working fluid in the turbine to produce power; directing a first portion of the expanded binary working fluid to a distiller/condenser; transforming the first portion of expanded binary working fluid into a first concentration binary working fluid, having a first concentration of a component of the binary working fluid, and a second concentration binary working fluid, having a second concentration of the component, in the distiller/condenser; directing at least the first concentration binary working fluid to a regenerative heat exchanger; directing a second portion of the expanded binary working fluid to the regenerative heat exchanger; transforming the first concentration binary working fluid into a vaporized binary working fluid and the second portion of expanded binary working fluid into a feed binary working fluid, in the regenerative heat exchanger; directing the feed binary working fluid to a vapor generator; vaporizing the feed binary working fluid in the vapor generator; combining the second concentration binary working fluid with the vaporized feed binary fluid to form the superheated binary working fluid; and actively regulating a flow of binary working fluid within the distiller/condenser to regulate a temperature of the superheated binary working fluid.
