l. HARTER METALLIC BAFFLE Filed Jun 19. 1925 064146 INVENTOR 4? J BY 1 ATTORNEYS Patented Dec. 3, 1929 UNITED STATES PATENT OFFIE ISAAC HARTER, 0F DONGAN HILLS, NEW YORK, ASSIGNOR TO THE BABC'OCK & WILCOX COMPANY, OF BAYONNE, NEW JERSEY, A CORPORATION OF NEW JERSEY METALLIC BAFFLE Application filed June 19, 1925.
My present invention relates to baflies for water tube boilers, and more particularly to baflies which extend parallel to the water tubes, and will be best understood from the following description and the annexed drawings in which Fig. 1 is a front view, partly broken away, showing a row of water tubes and the filling pieces therebetween constituting a baflie; Fig. 2 is a section along the line '22 of Fig. 1 and Fig. 8 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, baliles are arranged parallel to the water tubes to direct the flow of the hot gases. Such bafiies are illustrated at 5 and 6 of Fig. 3, the former extending down from the drum 7 along the front of the bank of water tubes, and the latter extending up from the drum 8 along the rear of the bank.
In the baflie of my present invention, 1 utilize a row of water tubes as part of the baffle and fill the space between the tubes with metallic baffle elements, 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 metallic baflie elements 2 are placed end to end in the spaces between adjacent water tubes 1 to form, with the tubes, a complete wall or bafile.
The bafiie elements 2 are shaped, as indi cated in section in Fig. 2, so that they have inwardly curved portions 3 on opposite sides forming exterior longitudinal concavities of the same curvature as the curvature of the outside of the tubes between which they are to be placed. These elements 2 also comprise portions 4: uniting the edges of the back portions 3 thus comprising hollow sections having concave and convex portions as illustrated.
Serial No. 38,198.
if necessary, to bring their ends into contact .55
with each other. Or, the elements 2 may be made of thin metal which is springy, so that they will yield sufficiently to permit the same to be forced into place between the tubes, and
will be held in place by their curved portions 150 3 resting firmly against the outside surfaces of the tubes between which they are placed. The result, usually, is a composite yielding of the elastic tube and of the resilient baffle section. It will thus be seen that the baffle elements 2, together with a row of tubes 1 constitute a baffle wall of the proper dimensions, and the curved surfaces of the elements 2 coming into close contact with the outside of the water tubes over a considerable area provide a very effective means for transferring the heat from the elements 2 to the tubes 1.
By my invention, a cheap and effective bame may be formed which can be readily maintained. .t will also be noted that by reason of the tight fit between the water tubes and bafiie elements, these elements will remain in position to form a baffle, as at 5, which does not have to be supported from below.
I claim 1. A baffle element for water tube boilers comprising a hollow metallic section having adjacent concave and yielding convex portions.
2. A bafiie element for water tube boilers comprising a hollow metallic section having concave portions on opposite sides thereof with their corresponding edges connected by yieldable intermediate portions.
. u 3. A baffle element comprising a hollow sheet metal element form d of curved intersecting surfaces, at least one of said surfaces being concave to engage an adjoining water tube.
4. A baffle element comprising a hollow sheet metal element formed with four curved sides, two of said sides being concave and disposed opposite to each other, whereby they may engage adjoining water tubes.
5. A bafiie element for Water tube boilers comprising a hollow metallic section having oppositely disposed concave portions adapted to engage adjoining tubes to hold the element 5 in position therebetween and yieldable portions connecting said concave portions.
