' COLUMBUS, OHIO GAS BURNER i 7 Application filed March 4, 1931. Serial No. 520,085.
This invention relates to improvements in gas burners and especially to gas burners of the type employed in conjunction with the radiant types of gas heaters, used generally for roomheating purposes, and it is an outstanding object of the invention to provide a highly eflicient burner for use in heat ore of this type which will be economical in operation and wherein complete combustion of the carburetted gaseous fuel takes place to the end of avoiding the development of noxious fumes or gases and to provide an even easily regulated flame.
It is another object of the invention to provide a gas burner which includesa mixing manifold into one end of which gas and air are admitted in regulated proportions to effect the formation of a primary mixture, the latter being conducted through the mani- 0 fold to the burner outlet ports thereof wh ch are adapted to be arranged in registration with the refractory heat radiating elements of gas heater, the mixer manifold being further formed with an independentchannel or conduit by which a stream of secondary air is permitted to pass through the manlfold and to combine with the primary combustible mixture issuing from the outlet ports, to the end that sufficient air will be added to the primary combustible mixture to effect complete and desired combustion thereof, the secondary air being supplied to the primary combustible mixture in such n'ianner as to avoid producing back pressures 3 5 in the mixer manifold or in any other way interfering with the desired flow of the com bustible gases through said manifold.
It is another object of the invention to provide the mixer manifold with improved means for effecting its support in conjunction with the frame structure of a heater.
With these and other objects in view, which will appear as the description proceeds, the invention consists in the novel features of construction, combination of elements and arrangement of parts hereinafter fully described and pointed out in the appended claims.
In the accompanying drawing:
Fig. 1 is a vertical sectional view taken through a mixer manifold, formed in accordance with the present invention; Fig. 2 is a transverse sectional view on the plane indicated by the line 2-2 of Fig. 1; Fig. 3 is a similar View on the line 3-3 of Fig. 1.
Referring more particularly to the drawing, the numeral 1 designates the improved mixer manifold comprising the present invention in its entirety. The manifold is of substantially hollow construction, having a no Venturi passage extending therethrough from end to end, the walls of the manifold being preferably formed from a cast metal. The air and gas passage through the manifold is indicated by the numeral 2 and when the manifold is used in a heater, the longitudinal axis of this passage is disposed at a severe angle to the vertical. The foot of the manifold is enlarged as at 3 and its open end is covered by a perforated circular plate .76 4 through which air is admitted from the atmosphere into the passage 2. Adjacent to this plate, the foot of the manifold is formed with a transversely extending web 5 which is formed Withan opening 6. adapted for the 175 reception of the cylindrical outlet portion of an orifice plug 7, the inner end of said plug being threaded into a similarly formed opening provided in a gas supply pipe 8. By this construction, the lower portion of 8 the manifold rests upon the shouldered intermediate portion of the plug 7 or, in other words, is supported by the pipe 8. Gas flows from the pipe 8 through the restricted orifice provided in the plug 7 and then passes di- I rectly into the lower portion of the passage 2, Where it is mixed with air drawn from the atmosphere and passed through the perforated plate 4. The opening 6 is of such di ameter as to permit the lower end of the manifold to freely pass over the cylindrical upper end of the plug 7.
The upper portion of the manifold terminates in an enlarged head 9 having a horizon tal Wall 10 in which is formed a plurality of outlet ports 11. The intermingled air and gas mixture, after passing through the man- 'ifold 1, issues from these outlet ports in a mixed or. carburetted state for combustion purposes. A particular feature of thepres- 1.1
the horizontal wall 10 in which the outlet.
ports 11 are provided. At the outlet of the passage 12, the latter is formed with a transversely extending web 14, which is arranged centrally of such outlet and is comparatively narrow in width so that air issuing from the outlet may pass on each side of the web.
Supported by the frame structure 14: of the heater in which the manifold is positioned, is a cylindrical outer radiant 15 and an inner conical radiant 15 composed of a heat treated ceramic material, the radiants being supported as usual in front of a re fractory backing 16, also supported by the frame structure 1 1. The lower portion of the radiant 15 is adapt-ed to engage with the upper edge of the web 14. The bar operates to deflect the secondary air stream issuing from the outlet of the passage 12, causing the secondary air to be intimately commingled with the primary combustible mixture issuing from the outlet ports 11. It will be observed that this operation takes place in such manner as to avoid interference with the flow of the primary combustible mixture so that the latter may pass freely and uninterrupted through the passage 2 of the manifold and avoids specifically the production of back pressures in said manifold which tend to interfere with the proper flow of the gases therethrough. By the construction comprising the present invention, the secondary air is merged with the primary mixture in an effective manner to produce a resulting final mixture which when burned produces a high temperature and a substantially complete elimination of noxious fumes or gases.
Adjacent to the upper portion of the manifold, the latter is provided with an integral offset tapered lug 19 which is adapted to be positioned in a correspondingly formed socket 20 carried by the frame structure 1 1 of the heater. By the provision of the opening 6 formed in the web 5, the lower end of the manifold is first readily positioned on the shouldered portion of the plug 7, and then by rocking the manifold bodily, the smaller end of the lug 19 may be positioned in the socket 20 and the entire manifold then forced into the supported position disclosed in Fig. 1. This permits of the convenient assembly of the manifold in a gas heater and avoidsparticularly the employment of separable threaded fastening elements.
What I have set forth, I consider to be a preferred form of the present invention. Nevertheless it will be understood that the burner mechanism herein disclosed is subject to considerable variation and modification without departing from the scope and spirit of the invention as the latter has been set forth in the following claims.
What is claimed is:
In a gas heater, in combination, a frame structure, a backing member supported by said frame structure, a radiant element adacent said member, a gas supply plpe arranged below and forward of said radiant,
an orifice plug connected to said pipe and positioned at an angle upward and inward in a directiontoward said radiant element, and a burner manifold formed with a burner head having its upper perforated wall arranged horizontally below said radiant, the mixing v conduit of said manifold being disposed at an angle upwardly and inwardly in a direction toward said radiant element, a burner manifold formed with a burner head having its upper perforated wall arranged horizontally below said radiant, the mixing conduit of said manifold being disposed at an acute angle relative to the upper perforated wall of said head and directed downwardly and for wardly to said orifice plug, and means for holding said manifold in its angular position relative to the radiant and said orifice plug.
In testimony whereof I affix my signature.
