Dec. 3, 1929. HARTER METALLIC BAFFLE Filed June 19. 1925 fl E IN1/Ewan I JM, ATTORNEYS.
Patented Dec. 3, 1929 UNITED STATES PATENT OFFICE ISAAC HARTER, OF DONGAN HILLS, NEW YORK, ASSIGNOR T0 THE BABGOCK & WILCOX COMPANY, OF BAYONNE, NEW JERSEY, A CORPORATION 0F NEW JERSEY METALLIC BAFFLE Application i1edV June 19,
Wy present invention relates to baffles for water tube boilers, and more particularly to baflles which extend parallel to the water tubes, and will be best understood from the following description and the annexed drawings, in which Fig. l is a front view, partly broken away, showing a row of water tubes and the filling pieces therebetween constituting a baffle; Fig. 2 is a section along the line 2-2 of Fig. l; Fig. 3 is a sect-ion similar to Fig. 2 showing a modification and Fig. 4l is a somewhat diagrammatic illustration on a small scale showing the disposition of the baffle in relation to a set of tubes of a Stirling boiler.
Like reference characters indicate like parts throughout the drawings.
As is well understood, in certain types of water tube boilers, such, for instance, as Stirling boilers, baffles are arranged parallel to the water tubes to direct the flow of the hot gases. Such baffles are illustrated at 8 and 9 of Fig. 4, the former extending down from the drum 10 along the front of the bank of water tubes, and the latter extending up from the drum 11 along the rear of the bank.
In the baffle of my present invention, 1 utilize a row of water tubes as part of the baffle and install baille elements in the space between the tubes, these baffle elements being preferably formed of sheet metal and arranged in position between the tubes with a large surface of the baffle elements contacting with the surfaces of the relatively cool water tubes so that the heat will be carried away from the elements and prevent their destruction.
As best shown in Figs. 1 and 2, a plurality of baffle elements 2 are placed end to end in the spaces between adjacent water tubes 1, to form with the tubes a complete wall or baffle. The baffle elements 2 are shaped, as indicated in section in Fig. 2, so that they have body portions provided with flanges 3 along each edge thereof, these flanges being curved, as indicated at 4, on a radius of curvature which is the same as the radius of curvature of the outside of the water tubes l between whichu they are to be placed. The element 2 may be inserted between the tubes by forcing the same 1925. Serial No. 38,199.
in, whereupon one or both of the flanges 3 will spring sufciently to permit the elements 2 to be inserted.
In the modification shown in Fig. 3, the baffle elements 5 have flanges 6 formed on their edges similar to the flanges 3 of the element 2, but instead of having these flanged extending on opposite sides of the baille element,these flanges 6 extend on the same side of the element 5 and are curved, as indicated at 7, to conform to the outer surface or curvature of the tubes l between which they are to be installed. These baffle elements can likewise be inserted by pressure, whereupon the flanges 6 will spring sufficiently to permit the same to be inserted.
It will thus be seen that the baffle elements 2- or 5, together with a row of tubes l, constitute a baffle wall of the proper dimensions, and the curved surfaces of the flanges of the elements 2 or 5 coming into close contact with the outside of the water tubes l over a considerable area to provide a very effective means for transferring the heat from the elements 2 or 5 to the tubes l. It will be seen y that each flange of an element contacts with and bears against a tube on a surface extending on both sides of the center line of the row of tubes in which the elements are disposed. Each element may be considered as formed of these two flanges, connected by a body extending between the flanges, and this body may take any desired form, two forms being exemplified in Figs. 2 and 3, respectively.
By my invention a cheap and effective baffle may be formed which can be readily maintained in place. It will alsol be noted that by reason of the tight fit between the water tubes and bafile elements, these elements will remain in position to form a baille, as at 8, which does not have to be supported from below.
I claim:
l. A baffle element for water tube boilers comprising a metal plate having a flange at each of its opposite edges, said flanges being curved transversely to fit the opposing walls of the adjacent water tubes, the body of said baffle element being wider than the distance between the tubes.
2. A baille element for water tube boilers comprising a metal member having a flange at each of its side edges curved to iit the water tubes, said flanges extending at an acute angle to the main body portion o'li said baille element.
3. A balile for a water tube boiler compris ing a row of water tubes spaced apart and sheet metal elements in the spacers between the tubes, each of said elements having a main `body portion wider than the distance between tubes and curved llange portions along opposite edges of said main body portion, said curved flanges litting snugly against said water tubes.
4. A battle for a water tube boiler comprising a row of water tubes spaced apart and metal elements in the spaces between the tubes, each of said elements having a main body portion and curved flange portions along opposite edges of said main body portion, said curved flanges being -disposed at an acute angle to said main body portion and fitting snugly against said water tubes.
5. A balile for a water tube boiler, comprising a row of water tubes spaced apart, and metal elements in the-spaces between the tubes, each of said elements having a main body portion and curved flange portions along opposite edges of said main body portion, said curved flanges being disposed at an acute angle to said main body portion and resiliently pressing against said water tubes.
6. In combination, a plurality of tubes disposed in a row and yieldable metallic baille elements disposed between the tubes in the row, each element comprising a body having curved flanges integral therewith, and each llange contacting with the adjacent face of adjoining tubes and extending on both sides of the center line of said row of tubes.
7. In combination, a plurality of tubes disposed in a row and yieldable metallic baliie elements disposed between the tubes in the row, each element comprising curved flanges, each lange contacting with the tubes adjacent thereto and extending on both sides of the center line of said row of tubes, and a body connecting said lianges and integral therewith.
8. In combination, a plurality of tubes disposed in a row and baille elements disposed between the tubes in the row, each element comprising a body portion, and yieldable means integral with said body portion resiliently holding said element in position independently of other elements.
9. In combination, a plurality of tubes disposed in a row and baHe elements disposed between the tubes in the row, each element comprising a body portion, and yieldable means integral with said body portion resiliently holding said element in position independently of other elements by contacting with adjoining tubes.
the tubes.
