Classification: F01K

Abstract:
A method of operating a power generation system having (i) a turbine for expanding a superheated multicomponent working fluid to produce power, (ii) a distiller/condenser for transforming the expanded multicomponent working fluid into a first concentration multicomponent working fluid, having a first concentration of a component of the multicomponent working fluid, and a second concentration multicomponent working fluid, having a second concentration of the component which is different than the first concentration, (iii) a boiler for vaporizing a feed multicomponent working fluid, and (iv) a superheater for superheating the vaporized feed multicomponent working fluid to form the superheated multicomponent working fluid, comprising the steps of:sensing a temperature of the vaporized multicomponent working fluid;combining the first concentration and the second concentration multicomponent working fluids to form a third concentration multicomponent working fluid, having a third concentration of the component different than the first concentration and the second concentration; andcombining the third multicomponent working fluid with the vaporized multicomponent working fluid to adjust the temperature of the vaporized multicomponent working fluid and thereby regulate the temperature of the superheated multicomponent working fluid.
