Patent ID: 8112997

Claim:
A power generating system including a working fluid circuit comprising: a condenser system in the working fluid circuit that receives a working fluid comprising steam or a combination of water and steam and condenses at least a portion of said working fluid into a condensate, said condensate having a temperature above a predetermined upper operating temperature; a condensate polisher circuit branched off from the working fluid circuit that receives and treats said condensate from the working fluid circuit and returns treated condensate to the working fluid circuit, said condensate polisher circuit comprising: a valve that controls a passage of said condensate into said condensate polisher circuit; a controller that controls an opening and a closing of said valve based on measurements received from at least one sample point; a heat exchanger that reduces said temperature of said condensate equal to or below said upper operating temperature; and a condensate polisher that removes contaminants from said condensate to bring said condensate to a predetermined purity.
