Abstract
Abstract A direct contact condenser in which a plurality of streams of water are discharged in a housing in a heat exchange relationship with steam passing therethrough to condense a portion of the steam. The condensed steam is reheated by redirecting the noncondensed steam in a heat exchange relation therewith, to remove air and other non-condensible gases from the condensed steam.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
A condenser comprising: a housing; means including at least one hollow partition disposed in said housing and having a plurality of through openings formed in a wall thereof for discharging a plurality of streams of water in said housing; means for passing steam in direct contact with said water to condense at least a portion of said steam, said condensed steam falling into a well portion defined in said housing and further comprising conduit means for passing said condensed steam from said well portion; means in said housing for heating a portion of said condensed portion of said steam to remove the non-condensibles therefrom, including means defining a deaerating section in said housing for receiving steam not condensed as a result of said contact with said water, a nozzle disposed in said deaerating section for receiving said portion of said condensed portion of said steam from said conduit means and discharging same towards said noncondensed steam in heat exchange therewith and vent means for removing said non-condensibles from said housing; and means for moving said portion of said condensed portion of said steam from said housing after the non-condensibles have been removed therefrom.
Claim 2
Dependent Claim
193 words
A condenser comprising: a housing; means including at least one hollow partition disposed in said housing and having a plurality of through openings formed in a wall thereof for discharging a plurality of streams of water in said housing; means for passing steam in direct contact with said water to condense at least a portion of said steam, said condensed steam falling into a well portion defined in said housing and further comprising conduit means for passing said condensed steam from said well portion; means in said housing for heating a portion of said condensed portion of said steam to remove the non-condensibles therefrom, including means defining a deaerating section in said housing for receiving steam not condensed as a result of said contact with said water, a nozzle disposed in said deaerating section for receiving said portion of said condensed portion of said steam from said conduit means and discharging same towards said noncondensed steam in heat exchange therewith and vent means for removing said non-condensibles from said housing; and means for moving said portion of said condensed portion of said steam from said housing after the non-condensibles have been removed therefrom.
Claim 3
Dependent Claim
23 words
The condenser of claim 1 including conduit means for directing said water from an external source to the hollow portion of said partition.
Claim 4
Dependent Claim
42 words
The condenser of claim 2 further comprising: means for connecting said nozzle to said conduit means for directing said water to said nozzle for discharging said water in the upper portion of said deaerating section to displace said non-condensibles out said vent.
Claim 5
Dependent Claim
22 words
The condenser of claim 1 further comprising a plurality of baffles in said deaerating section for defining a path for said steam.
Claim 6
Dependent Claim
38 words
The condenser of claim 1 wherein said water also passes into said well portion after said contact with said steam, said passing means adapted to pass a mixture of said water and said condensed steam to said nozzle.
Claim 7
Dependent Claim
74 words
The condenser of claim 1 wherein a well portion is defined in said housing for receiving a mixture of said water and said condensed steam, and further comprising first pump means for directing a portion of said mixture to said deaerating section for passage in said heat exchange relation with said non-condensed steam, and second pump means for directing another portion of said mixture to a cooling tower for passage to said discharging means.
Claim 8
Dependent Claim
37 words
The condenser of claim 6 further comprising means for discharging a portion of said other portion of said mixture into said deaerating section, and means for directing said later portion from said deaerating section to said well.
