1 Claim.
This invention relates to radiation shields for furnace heating sections, and more particularly pertains to upright heating sections of cylindrical form.
Objects of the invention are to provide a radiation shield and manner of mounting the same which may be cheaply manufactured, transported without danger of impairment, easily applied, and silent in operation thereafter; it being well known in the art, that such accomplishments heretofore have caused great difliculties.
Further objects and advantages will be apparent from the following description taken in connection with the accompanying drawings wherein Figs. 1 and 2 are plan and typical sectional elevation respectively of the heating section of the cylindrical heating section of a furnace with radiation shield mounted thereon, embodying the invention,
Fig. 3 is an enlarged detail in horizontal section as in. the plane of line 3-3, Fig. 2, illustrating a joint in the shield,
Fig. 4 is a development of the shield in flat form as before mounting on the section, and
Figs. 5 and 6 are details in elevation and end view respectively, showing the drive cleat employed at the aforementioned joint.
With reference now to the drawings, the heating section chosen for illustration is generally annular having cylindrical concentric inner and outer walls I and 2 respectively with top and bottom end walls 3 and d interconnecting them. The heating section may also embrace a pouch 5, opening into its bottom portion for disposition of gas burner means therein, and a flue outlet 6 at its upper end, opposite the pouch. Such general type of heating section is well known in the art and flow takes place therethrough from the pouch 5, about the inner wall I, and to the flue outlet 6 as indicated by the arrows a and b, Fig. 2.
According to this invention an open-ended cylindrical radiation shield is provided about the heating section in spaced relation thereto to provide an annular vertical space C through which upward circulation of air may be had as indicated by the vertical arrows Fig. 1. For the purpose a pair of rings are mounted on the section, including a ring I at the top of the section and a ring 8 above the pouch 5. The rings are of the same diameter, and are concentrically mounted on the section as by radially extending brackets 9 spaced thereabout and welded to the section. The rings may be welded or otherwise secured to the brackets.
The radiation shield i0 is of the usual sheet metal, of size to be wrapped around the two rings 1' and 8 as illustrated Figs. 1 and 2. At its lateral extremities the shield is provided with turnedback edges as at lfla by which its ends may be secured together, fitting about the rings, by employment of a drive cleat l l. The upper corners of the sheet which forms the radiation shield, are cut away as indicated Fig. 4 to clear the flue outlet 6, so that in assembly the joint is at the back of the furnace heating section and extends from the bottom of the radiation shield up approximately to the flue outlet; in assembly the cleat being driven upwardly toward the flue outlet with the section tilted from vertical.
For maintaining the shield in mounted position a number of clips it?) are provided, spaced along its upper edge, which clips may be turned inwardly and downwardly over the upper ring I. Preferably, three of such clips only are provided, located to be apart about the section, with one above the pouch 5 as indicated Fig. 1. The shield is thus supported from the upper ring 7. By the lower ring 8 the shield has no support, this ring serving merely to locate the lower shield extremity.
In practice the shield is shipped closely rolled in cylindrical form about an axis parallel to its deformed edges Illa so that the sheet of metal is not otherwise permanently deformed. In its application to the section, the rings about which it is wrapped preserve its cylindrical form, which is also preserved by the relatively rigid edge portions Elia and thereafter by the cleat H. Thus application of the shield to the heating section at the location of erection of the furnace is facilitated and the shield completely installed, without acquiring any warped surfaces.
Thereafter, under the changingtemperature conditions to which such a shield is subject in operation of the heating section, the manner of mounting permits vertical expansion relative to the heating section without the noises all too frequently caused under such conditions, the shield being wholly supported by the upper ring l at three places only, and relatively free at its lower end, being merely there located by the lower ring 8.
I claim:
In combination with an upright cylindrical furnace heating section, radiation shield means therefor comprising: a pair of rings of greater diameter than said section mounted thereon disposed concentrically thereabout at locations spaced therealong to define an open ended annular air passage, about said section, a piece of sheet metal having flanged opposite edges, said piece being Wrapped about said rings with said edges longitudinally extending adjacent each other, and cleat means slidably interconnecting said edges by engagement with their flanges, said sheet metal piece having clip means secured thereto at locations spaced along its upper edge and bent over the upper of said rings for its detachable support thereon, said piece freely bearing about the lower of said rings to be sgaced from said section thereby while permitting free longitudinal expansion relative thereto.
EDWARD R. DOWNE.
