Abstract
Abstract An annular liquid-distributing chamber encircles the exterior shell of a furnace and has an open space in the bottom wall thereof extending the entire length of the chamber. A resilient sealing strip attached to the chamber bottom wall extends across the open space into contact with the exterior shell so as to distribute cooling liquid therealong. One or more conduits deliver cooling liquid to the chamber behind a weir over which liquid flows to the sealing strip. A trough spaced below the chamber receives cooling liquid after it has traveled downwardly along the shell surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
Apparatus for cooling the exterior shell of a furnace comprising: a. an annular liquid-distributing chamber adapted to be attached to the furnace so as to encircle the exterior shell thereof and having a liquid discharge portion adjacent the furnace shell; b. a sealing strip of resilient material encircling the furnace shell and connected to said chamber, said strip being disposed in wiping relation to the furnace shell when said chamber is attached thereto; and c. means for delivering cooling liquid to the interior of said chamber; d. whereby in response to the weight of cooling liquid thereon said sealing strip flexes so as to cause a film of cooling liquid to flow downwardly along the furnace shell.
Claim 2
Dependent Claim
117 words
Apparatus for cooling the exterior shell of a furnace comprising: a. an annular liquid-distributing chamber adapted to be attached to the furnace so as to encircle the exterior shell thereof and having a liquid discharge portion adjacent the furnace shell; b. a sealing strip of resilient material encircling the furnace shell and connected to said chamber, said strip being disposed in wiping relation to the furnace shell when said chamber is attached thereto; and c. means for delivering cooling liquid to the interior of said chamber; d. whereby in response to the weight of cooling liquid thereon said sealing strip flexes so as to cause a film of cooling liquid to flow downwardly along the furnace shell.
Claim 3
Dependent Claim
36 words
The cooling apparatus defined in claim l further including means for receiving and draining liquid adapted to be attached to said furnace below said chamber so as to receive cooling liquid flowing downwardly along the shell.
Claim 4
Dependent Claim
38 words
The cooling apparatus defined in claim 1 further including a weir in said chamber extending along the entire circumferential length thereof and positioned so as to deliver a circumferentially continuous flow of cooling liquid onto said sealing strip.
Claim 5
Dependent Claim
21 words
The cooling apparatus defined in claim l wherein said sealing strip comprises a plurality of rubber sections positioned in end-to-end contact.
Claim 6
Dependent Claim
140 words
Apparatus for cooling the exterior shell of a furnace comprising: a. an annular liquid-distributing chamber adapted to be attached to the furnace so as to encircle the exterior shell, said chamber having a bottom wall which terminates a distance from the shell so as to define an open space therebetween and disposed circumferentially thereof; b. a sealing strip of resilient material encircling the furnace shell, said strip being attached to said chamber bottom wall and being disposed so as to extend therefrom into wiping contact with the furnace shell when said chamber is attached thereto; c. a weir in said chamber attached to said chamber bottom wall and extending for the entire length of said chamber; and d. conduit means for delivering cooling liquid to the interior of said chamber on the side of said weir remote from the furnace.
Claim 7
Dependent Claim
140 words
Apparatus for cooling the exterior shell of a furnace comprising: a. an annular liquid-distributing chamber adapted to be attached to the furnace so as to encircle the exterior shell, said chamber having a bottom wall which terminates a distance from the shell so as to define an open space therebetween and disposed circumferentially thereof; b. a sealing strip of resilient material encircling the furnace shell, said strip being attached to said chamber bottom wall and being disposed so as to extend therefrom into wiping contact with the furnace shell when said chamber is attached thereto; c. a weir in said chamber attached to said chamber bottom wall and extending for the entire length of said chamber; and d. conduit means for delivering cooling liquid to the interior of said chamber on the side of said weir remote from the furnace.
Claim 8
Dependent Claim
37 words
The cooling apparatus defined in claim 5 further including trough means for receiving and draining liquid adapted to be attached to said furnace below said chamber so as to receive cooling liquid flowing downwardly along the shell.
Claim 9
Dependent Claim
33 words
The cooling apparatus defined in claim 5 wherein said chamber bottom wall is disposed in a horizontal plane and wherein said weir and said sealing strip are inclined relative tO said bottom wall.
Claim 10
Dependent Claim
21 words
The cooling apparatus defined in claim 5 wherein said weir and sealing strip are adjustably attached to said chamber bottom wall.
Claim 11
Dependent Claim
28 words
The cooling apparatus of claim 1 on a furnace having a downwardly inclined shell portion, said sealing strip being in wiping relation to said downwardly inclined shell portion.
