Deaerator apparatus in a superatmospheric condenser system
First Claim
1. A power generating system comprising:
- a condenser that receives steam or a combination of water and steam and condenses the steam or combination of water and steam into a condensate, said condenser operating at an internal pressure above ambient pressure during a normal operating mode of said condenser;
a condensate treating apparatus that removes contaminants from said condensate to bring said condensate to a desirable purity, said condensate treating apparatus being deactivated during a typical operating state of the power generating system such that said condensate bypasses said condensate treating apparatus, and said condensate treating apparatus being activated during a non-typical operating state of the power generating system such that said condensate passes into said condensate treating apparatus wherein contaminants can be removed from said condensate, said typical operating state of the power generating system occurring when the condensate comprises said desirable purity and said non-typical operating state of the power generating system occurring when the condensate comprises an undesirable purity; and
wherein, during a time in which said condenser operates in said normal operating mode at the internal pressure above ambient pressure, the power generating system operates in said non-typical operating state a first portion of the time and operates in said typical operating state a second portion of the time.

Abstract
A power generating system comprises a condenser and a deaerator apparatus. The condenser condenses a working fluid into a condensate and operates at an internal pressure above ambient pressure during a normal operating mode. The deaerator apparatus uses steam to remove contaminants from the condensate to bring the condensate to a desirable purity. The deaerator apparatus is deactivated during a typical operating state of the power generating system such that the condensate bypasses the deaerator apparatus. The deaerator apparatus is activated during a non-typical operating state of the power generating system such that the condensate passes into the deaerator apparatus wherein contaminants can be removed from the condensate. The typical operating state of the power generating system occurs when the condensate comprises a desirable purity and the non-typical operating state of the power generating system occurs when the condensate comprises an undesirable purity.

14. A method of treating condensate that has been condensed in a condenser adapted for use within a steam generating system including a working fluid circuit, the condenser operating at an internal pressure above ambient pressure during a normal operating mode of the condenser, the method comprising:
-
bypassing the condensate past a condensate treating apparatus during a typical operating state of the steam generating system, the typical operating state occurring when the condensate comprises a desirable purity; passing the condensate through the condensate treating apparatus during a non-typical operating state of the steam generating system, the non-typical operating state occurring when the condensate comprises an undesirable purity, wherein passing the condensate through the condensate treating apparatus comprises; passing the condensate into the condensate treating apparatus; removing contaminants from the condensate; passing the condensate out of the condensate treating apparatus; measuring a purity of the condensate after contaminants have been removed therefrom by the condensate treating apparatus; and continually passing the condensate through the condensate treating apparatus until the condensate comprises a desirable purity. - View Dependent Claims (15, 16, 17, 18, 19, 20)
