Abstract
Abstract Portions of metal members having high thermal conductivity extend inwardly of a stack with other portions thereof extending outwardly of stack and out of contact with steam and other gaseous products conveyed by the stack reducing temperature of the inwardly extending portions by conduction of heat to other portions. Collector means receives water condensed onto the inwardly extending portions and discharge means removes water from the collector means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
In apparatus for removing steam from a moving column of steam and other gaseous products: a. a discharge stack carrying said column of steam and other gaseous products, b. a plurality of elongated metal members each having high thermal conductivity with one portion thereof extending upwardly and inwardly within said stack from a side thereof and another portion thereof extending outwardly of said stack, c. means supporting each said metal member with said one portion in position to be contacted by said steam and other gaseous products and with said another portion out of contact with said steam and other gaseous products so that said another portion reduces the temperature of said one portion by conduction of heat away from said one portion whereby steam is condensed into water onto said one portion of said metal member, d. collector means including a collector ring mounted at the inner surface of said stack receiving said water condensed onto said one portion of said metal members, and e. water discharge means communicating with said collector means.
Claim 2
Dependent Claim
174 words
In apparatus for removing steam from a moving column of steam and other gaseous products: a. a discharge stack carrying said column of steam and other gaseous products, b. a plurality of elongated metal members each having high thermal conductivity with one portion thereof extending upwardly and inwardly within said stack from a side thereof and another portion thereof extending outwardly of said stack, c. means supporting each said metal member with said one portion in position to be contacted by said steam and other gaseous products and with said another portion out of contact with said steam and other gaseous products so that said another portion reduces the temperature of said one portion by conduction of heat away from said one portion whereby steam is condensed into water onto said one portion of said metal member, d. collector means including a collector ring mounted at the inner surface of said stack receiving said water condensed onto said one portion of said metal members, and e. water discharge means communicating with said collector means.
Claim 3
Dependent Claim
32 words
Apparatus for removing steam from a moving column as defined in claim 1 in which a plurality of said metal members extend through said stack and are spaced angularly from each other.
Claim 4
Dependent Claim
28 words
Apparatus for removing steam from a moving column as defined in claim 2 in which at least some of said metal members are spaced vertically from each other.
Claim 5
Dependent Claim
39 words
Apparatus for removing steam from a moving column as defined in claim 2 in which heat insulation means is mounted between said metal members and said stack reducing the conduction of heat from said stack to said metal members.
