Abstract
Abstract A wall of a refractory furnace comprises a plurality of refractory blocks positioned in side-by-side and/or end-to-end relationship. Each of the blocks is provided with a through passage and a structural member traverses the passage for anchoring the blocks to a supporting structure. The structural member may pass through a number of blocks placed in end-to-end relationship and the fluid medium may be conveyed through the passages for thermally conditioning the wall of the furnace.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
In a refractory furnace for the treatment of glass floating on a tank containing a bath of molten material, a refractory furnace wall being formed of a plurality of refractory blocks positioned transversely within the said wall, each of said blocks having an aperture therein which is alignable with adjacent blocks as assembled to define a continuous passageway through the assembly of blocks, elongated block-anchoring means disposed within said passageway and extending throughout the length thereof and firmly anchoring the aligned blocks together, conduit means disposed within at least a portion of said anchoring means and having means for discharging a fluid into the interior of said block-anchoring means for thermal conditioning of said wall, and means for controlling the zone of discharge of said fluid for regulating the temperature along the length of said passageway.
Claim 2
Dependent Claim
136 words
In a refractory furnace for the treatment of glass floating on a tank containing a bath of molten material, a refractory furnace wall being formed of a plurality of refractory blocks positioned transversely within the said wall, each of said blocks having an aperture therein which is alignable with adjacent blocks as assembled to define a continuous passageway through the assembly of blocks, elongated block-anchoring means disposed within said passageway and extending throughout the length thereof and firmly anchoring the aligned blocks together, conduit means disposed within at least a portion of said anchoring means and having means for discharging a fluid into the interior of said block-anchoring means for thermal conditioning of said wall, and means for controlling the zone of discharge of said fluid for regulating the temperature along the length of said passageway.
Claim 3
Dependent Claim
16 words
In a refractory furnace wall as claimed in claim 1 wherein said anchoring means is tubular.
Claim 4
Dependent Claim
17 words
In a refractory furnace wall as claimed in claim 1 wherein said anchoring means is an angle.
Claim 5
Dependent Claim
19 words
In a refractory furnace wall as claimed in claim 1 wherein each block is molded onto said anchoring means.
Claim 6
Dependent Claim
19 words
In a refractory furnace wall as claimed in claim 1 wherein said anchoring means has clearance within said passage.
Claim 7
Dependent Claim
21 words
In a refractory furnace wall as claimed in claim 1 wherein said conduit means has fluid discharge orifices within each block.
Claim 8
Dependent Claim
42 words
In a refractory furnace wall as claimed in claim 6 wherein there being a series of said orifices along the length of said conduit means with the spacing between successive orifices decreasing from the ends of the block toward the center thereof.
Claim 9
Dependent Claim
33 words
In a refractory furnace wall as claimed in claim 6 and comprising means upon said conduit and displaceable longitudinally thereon for masking said orifices to control the discharge of fluid from the conduit.
Claim 10
Dependent Claim
33 words
In a refractory furnace wall as claimed in claim 1 and means for transferring a greater portion of the heat in the central area of the furnace than in the lateral areas thereof.
