T-EXCHANGING STONE FOR Am TEES AND THE LIKE Application filed August 5, 1927, Serial No. 210,995, and in Germany'septeinber an, 19%. 1
This invention relates to heat exchanging stones of the kind, of which a plurality is inaccumulate the heat of furnace gases or the t like and to transmit thereafter this heat to air or another gas. More especially, the improved stones forming the subect-matter of this invention are'inte'nded for the production .of a heat-exchanging structure having narbelow 100 mm. clear width, and having only thin walls between the channels or passages, viz. below mm.
- Such stones (which may be comparatively long so as to resemble tubes) are only small in section and only little resistible to bending or warping, and there exists, thus, the danger that a stone of "any of the constructional forms used at present is bent if the stones carried by it are not located perfectly vertically and centrally onit, the result otherwise being that the upper stones tumble down, are also bent, displace the adacent stones and cause in the whole very great disorder, whereby the usefulness of the air-heater is severely disturbed, if not the entire heater is rendered useless for the time being.
The object of the invention is to obviate I such occurrences, and this object is attained 30 by uniting with each bther a plurality of airexchanging stones having channels or passages of the small diameter, and walls of the slight thickness, above stated, there being obtained a heat-exchanging body having a cor-- responding plurality of the small channels or assages and between them the thin walls, but heing by far more resistible against bending and compression and having such a strength that the heat-exchanging structure composed of these multipleor compound-stones is completely prevented from collapsing, and the proper service of the air-heater is, therefore, never disturbed.
The invention is illustrated diagrammatically and by way of example on the accompanying drawing on which Figure 1 is a topview of a multipleorcomp'ound-stone formed by the union of four octangularv stones, Figure 2 is a top-View of a modification in which four 50 star-shaped stones are united with each other,
row vertical channels or passages, viz. such and Fig. 3 is a top-view of another modification composed of four tubular stones. sorted into an'air-heater or the like in order to 1 In Fi 1 fouroctagonal stones A are united integra y with each other. Each has a circular channel or passage a' of about 70 mm.,
diameter or less, and between the four stones,
or centrally in the multiple-stone A, is a quadrangual channel or passage 5 of about 50 mm. clear width or less, whereas rectangular grooves c are provided at the four sides of the stone A. It will be obvious without a more detailed explanation that two grooves c of two neighbouring multiple-- stones like A form a channel orpassage like I), and thls is true, of course, of all stones forming the structurebuilt into the heater.
In Fig. 2 three star-shaped stones are uni formly distributed around a central starshaped stone,all fourtogether forming a multipleor compound-stone B having four circular channels or passages d and three each a circular channel or passage resembling the channels or passages a 1n ig. 1 and d in Fig. 2. The grooves h are'closed by the neighbouring stones C so as to form channels or passages of the sectional shape 2'.
The thickness of the walls between the pas sages or channels is in all cases less than 50 mm. I wish it to also other constructionalforms are possible without departing from this invention. I claim:
be understood that '1 do not limit myself to the few examples shown on. the drawing. Experts will understand that 1. A heat-exchanging stone for heat exchanging structures in air heaters and the like, said stone comprising a plurality of units each of a regular geometrical figure having a passageway extending axially therethrough, said units being integrally connected together.
2. A heat-exchanging stone for heat exchanging structures in air heaters and the a like, comprismg a plurality of units, each of said units comprising a regular geometrical figure in cross section, each of said units having a central passageway therethrough disposed symmetrically with respect to said unit and having non-square corners whereby said units in cooperation with one another provide passageways at said non-square corners, said units being integrally united toether.
In testimony whereof I aifix m signature.
