Abstract
Abstract A fluid heating and separating apparatus in which an upper separating chamber and a lower heating chamber are defined in a pressure vessel, and a relatively hot fluid is introduced into the heating chamber. A relatively cool fluid is passed through the heating chamber in a heat exchange relationship with the relatively hot fluid to heat the cool fluid and condense at least a portion of the hot fluid. The chambers are in communication to permit the passage of the light portions of the hot fluid from the heating chamber into the separating chamber in which it is separated into a vapor portion which is passed outwardly from the vessel, and a liquid portion which is passed back into the heating chamber.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A fluid heating and separating apparatus comprising a pressure vessel, means defining an upper separating chamber and a lower heating chamber in said vessel, an inlet communicating with the upper portion of said heating chamber for introducing a relatively hot fluid into said heating chamber, a plurality of tubes in said heating chamber, means for passing a relatively cool fluid from an external source through said tubes, the relatively heavy portion of said hot fluid passing downwardly in said heating chamber across said tubes in a heat exchange relation with said cool fluid to heat said cool fluid, means connecting said chambers to permit the passage of the relative light portion of said hot fluid from said heating chamber into said separating chamber, and means in said separating chamber for separating the vapor portion of said relatively light portion of hot fluid from the liquid portion thereof.
Claim 2
Dependent Claim
147 words
A fluid heating and separating apparatus comprising a pressure vessel, means defining an upper separating chamber and a lower heating chamber in said vessel, an inlet communicating with the upper portion of said heating chamber for introducing a relatively hot fluid into said heating chamber, a plurality of tubes in said heating chamber, means for passing a relatively cool fluid from an external source through said tubes, the relatively heavy portion of said hot fluid passing downwardly in said heating chamber across said tubes in a heat exchange relation with said cool fluid to heat said cool fluid, means connecting said chambers to permit the passage of the relative light portion of said hot fluid from said heating chamber into said separating chamber, and means in said separating chamber for separating the vapor portion of said relatively light portion of hot fluid from the liquid portion thereof.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 wherein said separating means comprises means for subjecting said relatively light portion of said hot fluid to a centrifugal action.
Claim 4
Dependent Claim
22 words
The apparatus of claim 1 further comprising means for passing said liquid portion from said separating chamber back to said heating chamber.
Claim 5
Dependent Claim
25 words
The apparatus of claim 1 further comprising outlet means in said separating chamber for permitting the passage of said vapor portion to an external source.
Claim 6
Dependent Claim
36 words
The apparatus of claim 1 further comprising an impingement baffle located in the path of said hot fluid entering said heating chamber through said inlet for preventing said hot fluid from directly impinging upon said tubes.
Claim 7
Dependent Claim
30 words
The apparatus of claim 1 further comprising outlet means in said heating chamber for permitting the passage of said relatively heavy portion of said hot fluid to an external source.
Claim 8
Dependent Claim
36 words
The apparatus of claim 1 wherein said relative light portion of said hot fluid passes from said heating chamber into said separating chamber by virtue of its buoyancy and the lower pressure in said separating chamber.
