TECHNIQUE FOR CONTROLLING REGENERATIVE SYSTEM CONDENSATION LEVEL

摘要

A method of operating a power generation system, such as a Kalina cycle power generation system, which includes a turbine (130), regenerative heat exchanger (140) and vapor generator (142), is provided. The turbine (130) receives a stream of first working fluid and expands the first working fluid to produce power. The regenerative heat exchanger (140) receives a stream of the expanded first working fluid from the turbine (130) and a stream of second working fluid, and transfers heat from the expanded first working fluid to the second working fluid to heat the second working fluid and condense the expanded first working fluid. The vapor generator (142) receives a stream of the condensed first working fluid and transfers heat from an external heat source to the condensed first working fluid to heat the condensed working fluid for use in the stream of first working fluid. The system is operable in a first state of substantial equilibrium with the stream of second working fluid being received at a first flow rate and in a second state of substantial equilibrium with the stream of second working fluid being regulated so as to be received at a second flow rate, different than the first flow rate.
