7 Claims.
Thisinvention relates to oil burning furnaces, and more particularly to a baflle designed in such a manner as to be readily installed in existing furnaces, and of a particular construction adapted to greatly increase the efiiciency of the furnace in operation.
The object of the invention is to provide an improved and simplified baflle adapted to be installed in oil burning furnaces.
The invention consists in a novel construction arrangement and combinations of parts hereinafter more particularly described and claimed.
One sheet of drawings accompanies this specification as part thereof, in which like reference characters indicate like parts throughout.
Figure 1 is a perspective view of an oil burning furnace partly broken away to illustrate the positioning of the improved baflle therein.
Figure Zis a fragmentary side elevation of the furnace illustrated in Figure l, partly broken away to show a vertical cross-section through the fire box.
Figure 3 is a horizontal cross-section taken on line 33 of Figure 2.
Referring to the drawing, the furnace I may be of any conventional type, but herein illustrated as a vertical water boiler having at its bottom a fire box of substantially rectangular shape, the walls of which are formed by fire bricks 2.
The improved bafile is formed of refractory material and comprises a trunk-line portion having a top 3, and somewhat wider bottom 4, with the side walls 5 converging inwardly from the bottom toward the top. as illustrated. Formed integrally with trunk portion of the battle are a plurality of laterally directed fins 6 preferably arranged in pairs transversely of the trunk part i and in alignment, these pairs of fins being spaced apart. Each of the fins 6 has a bottom face 1 inclined outwardly and upwardly from the bottom 4 of the trunk part of the baffle.
The trunk part of the baffle extends at each end beyond the end pair of fins to support the baffle by resting on the top of the fire brick liners 2, and these end portions of the baffle may be conveniently formed with grooves I2, to assure cleavage in a predetermined plane, so that in the installation of the baffle in existing furnaces the length of the bafile can be determined by removing one or both of the end portions as may be necessary.
To assure the proper combustion of the fuel within the fire box and avoid the formation of carbon on the baflle the installation of the baflle has been found to be critical, inthat the baflle should be positioned above the inlet in for the fuel at a greater distance than the height of the fuel inlet above the floor of the fire box, and in actual practice it has been found that the distace 8 between the baflle and the fuel inlet will operate most efficiently when it is one and onequarter times the distance 9 between the fuel inlet and the bottom of the fire box.
When designed and installed as specified it has been found that the gases of combustion are directed in substantial quantity outwardly toward the side walls of the furnace, while a smaller portion of these gases is directed upwardly be- I tween the pairs of fins, producing a greatly increased heat in the fire box and substantially lowering the temperature in the chimney. None of the gases or flame is directed toward the front or door side of the furnace. A reduction of the oil fed to the furnace may be made immediately upon the installation of the baffle, to produce the same heating effects.
Various modifications in details will readily suggest themselves to those skilled in the art, and any of many well known refractory materials can be used in the construction of the baffle.
What I claim as my invention is:
1. Baflie for oil burning furnaces comprising a refractory member of a length substantially that of the fire box of the furnace having a medial trunk with a plurality of laterally extending vertically disposed spaced fins on each side of said trunk, said fins each having inclined bottom faces extending outwardly and upwardly from the bottom face of the trunk part.
2. The device of claim 1 in which the lateral fins are arranged in pairs in alignment transversely of the trunk part.
3. The device of claim 1 in which the trunk part has a bottom faco wider than its top face and side faces converging upwardly and toward the center of the trunk and the fins are arranged in transversely aligned pairs with their bottom faces converging from the top inwardly and downwardly to the sides of the bottom face of the trunk part.
4. The device of claim 1 in which the trunk part extends at each end beyond the fins to support the device on the fire box.
5. The combination in an oil burning furnace of a fire box into which a fuel atomizer discharges from one side, a refractory baflie extending in alignment with the fuel atomizer said baflie formed with a medial trunk part and having on each side a plurality of laterally directed spaced vertically disposed fins, said fins having bottom faces inclined upwardly and outwardly from the bottom face of the trunk part to direct a substantial portion of the gases of combustion outassacaa tom face of the trunk outwardly and upwardly toward the top lace oi. the trunk.
7. Inen oil burning furnace having a fire box and a fuel atomizer discharging across the fire box, a refractory bafile formed with a. medial trunk part and a plurality of laterally directed vertically disposed fins on each side, said fins arranged in transversely aligned pairs spaced apart longitudinally of the trunk part, said bame supported by the ends of the trunk part with the fins extending transversely of the atomizer.
