JOHN W. THROCKMORTON BY ATTORNEY.
Patented June 20, 1950 FURNACE CONE OF SEPARABLE CONSTRUCTION John W. Throckmorton, New York, N. Y., assignor to Petra-Chem Process Company Incorporated, New York, N. Y., a corporation of Dela- Ware Application January 5, 1949, Serial No. 69,295
Claims.
This invention pertains to cone bafiles of the type used in vertical furnaces for deflecting com-.
bustion gases outwardly into the passage between the radiant and convective sections of the furnace.
An object of the invention is to provide a cone of very durable and substantial construction, and built up of elements which may be readily assembled and as readily replaced in Whole or in part.
Further and other objects and advantages will be apparent from the specification and claims, and from the accompanying drawings which illustrate what is now considered to be a preferred embodiment of the invention.
In the drawings:
Fig. 1 is a general view of the invention mostly in cross-section;
Fig. 2 is a cross-section on line 2--2 of Fig. 1;
Fig. 3 is an enlarged detail view on line 3-3 of Fig. l; and
Fig. 4 is an enlarged detail view on line 44 of Fig. 1.
The furnace comprises an outer cylindrical sheet metal shell Ill lined with insulation l2 and fire brick l4.
Within the ring of fire brick, and spaced therefrom, is a ring of refractory material It. The heat exchange tubes I8 pass vertically through the restricted space between rings I4 and i6 and in that restricted space the tubes are provided with fins 20.
The refractory ring it rests on the horizontal upper surface 22 of an angle ring which has a downwardly extending flange 24 (Figs. 1 and 3). The ring is supported by twelve equally-spaced vertical rods 26 attached at 28 to the furnace super-structure.
Ring 2224 is the upper, and supporting, member of the cone which is the subject matter of the present invention.
The ring is formed of arcuate sections, each covering one sixth of the circumference. Each end of a section has a vertical rib 30 (Figs. 1 and 3), provided with holes 32, through which the sections are bolted together to complete the ring.
Each of the six ring sections is supported by two of the vertical rods 26, each rod having a nut 34 on its lower end (Fig. 3). On both sides of each nut 34 are integral triangular ribs 36 (similar to rib 30, but without holes 32), thus forming pockets accommodating nuts 34, and also providing spaces for hanger lugs 38 which are secured by bolts 40 to the vertical member 24 of the supporting ring.
Screwed into lugs 38 are the upper ends of rods 42, the lower ends of which support cone tip 44 by engaging angle brackets 46 spaced internally 2 around the upper rim of the cone tip (Figs. 1, 2, 4).
The space between ring 22-24 and cone tip 44 is enclosed by circumferential overlapping plates 48 bolted or riveted together along their edges and secured at their upper ends by bolts 40 to the member 24 of the supporting ring, and are free to expand over cone tip 44.
It is to be understood that the invention is not limited to the specific embodiment herein illustrated and described, but may be used in other ways without departure from its spirit as defined by the following claims.
I claim:
1. A cone baflle for a vertical furnace, comprising in combination, an annular ring having a rim forming the cone top, a conical tip forming the cone bottom and segmental plates joinin said rim and said conical tip.
2. A cone bafiie for a vertical furnace, comprising in combination, a segmental annular ring having a rim forming a cone top, a conical tip forming the cone bottom, rods supporting said tip from said rim, and segmental plates surrounding said rods and detachably attached to said rim and engaging said conical tip.
3. Cone baffle construction for upright furnaces comprising a cone ring, a cone tip, segmental plates forming the sides of the cone between the ring and tip, said plates being afiixed to the ring and engaging said tip, and hanger supports attached to the ring for suspending the baffle within the furnace in an inverted position.
4. A bafile construction as in claim 3 with internal stay rods extendin from the ring to the tip, said rods being attached to said ring and tip.
5. Cone baffle construction for upright furnaces comprising a ring having an acute angled cone rim, a cone tip, segmental plates extending therebetween said plates being affixed to the rim and engaging said tip, internal fastenings disposed at intervals about the interior of the cone ring and cone tip and stay rods extending between the fastenings, and hangers for suspending the cone assembly within the furnace.
JOHN W. THROCKMORTON.
