Abstract:
A method of operating a Kalina cycle power generation system, comprising the steps of:directing a stream of vaporized binary working fluid to a turbine;expanding the vaporized binary working fluid in the turbine to produce power;directing a first portion of the expanded binary working fluid to a distiller/condenser having multiple heat exchangers;transforming the first portion of expanded binary working fluid using the multiple heat exchangers, 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; andactively regulating a binary working fluid flow within the distiller/condenser to maintain a relationship between the multiple heat exchangers.
