How does regenerative condenser work
Purpose of regenerative condenser
- to increase thermal efficiency by using some of the steam in the shell of the condenser to reheat the falling condensate to be used for boiler feed water
How does regenerative condenser work:
- baffle plates in a shell and tube condenser are arranged in a configuration which allows most of the steam that enters the shell of the condenser to come in contact with the cooling tubes containing the cooling medium
- majority of the steam then condenses and fall to the condenser hot well
- a portion of the steam, however, is distributed by means of the design of the baffle plates so that it will direct this portion of steam to bypass the cooling tubes and flow directly to the bottom of the shell in order to reheat the falling condensate (the condensate which was the "most of the steam", that is now condensed by means of the cooling medium in the tubes)
- this process will make the temperature of the condensate from the hot well to approach the saturation temperature at condenser pressure
- when the condensate is near the saturation point, the unwanted corrosive non-condensable gases such as oxygen and carbon dioxide will escape
