Condensate Polisher Circuit
First Claim
1. 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 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.

Abstract
A power generating system including a working fluid circuit. The power generating system includes a condenser system in the working fluid circuit and a condensate polisher circuit. The condenser system receives a working fluid that includes steam or a combination of water and steam and condenses at least a portion of the working fluid into a condensate. The condensate has a temperature above a predetermined upper operating temperature. The condensate polisher circuit is branched off from the working fluid circuit and receives and treats said condensate from the working fluid circuit and returns treated condensate to the working fluid circuit. The condensate polisher circuit includes a heat exchanger that reduces the temperature of the condensate at least to the upper operating temperature and a condensate polisher that removes contaminants from the condensate to bring the condensate to a predetermined purity.
