3 Claims.
My invention relates to an improvement in pot type burners and has for one purpose to provide an improved burner pot.
Another purpose is to provide improved means for stabilizing combustion in said pot.
Another purpose is to provide improved means for recirculating gases in said pot.
Other purposes will appear from. time to time in the course of the specification.
I illustrate my invention more or less diagrammatically in the accompanying drawing wherein:
Fig. 1 is a vertical axial section;
Fig. 2 is a section on a reduced scale on the line 2-2 of Fig. l; and I Fig. 3 is a vertical axial section on a reduced scale of a variant form of the device.
Like parts are indicated by like symbols throughout the specification and claims.
Referring to the drawing, I generally indicates an outer housing, which may be of any suitable shape, but is herein shown as a cylinder or drum.
-It may be supported in any suitable fashion by legs or other supports 2, which space the lower edge of the drumfrom the floor. 3 indicates a bottom partition having a central air inlet apermm 4. 5 is a pot having an upper outwardly extending flange 6, which may rest on a ring or any other suitable support 1 extending inwardly from the inner face of the housing I. I
8 is a fuel pipe extending from any suitable source of fuel. It will be understood that any suitable means for regulating the flow of fuel inwardly along the pipe 8 may be employed, for example a conventional float valve, and it will be understood that variations of flow may be obtained manually or thermostatically, such control devices not of themselves forming part of the present invention. It will be understood that any suitable means for varying the flow of fuel to the burner may be employed, preferably maintaining a minimum flow suflicient to support combustion in the burner at the pilot stage.
The wall of the pot 5 is provided with a plurality of air inlets I0, located at various levels, and herein shown as arranged in a plurality of horizontal planes. All of the apertures I0, when the device is burning at the high fire, serve-as primary'air apertures. Secondary air may be admitted adjacent the top of the pot in any suitable fashion. I illustrate, however, a single row of larger and more closely spaced inlets II, which are shown as upwardly and inwardly tilted and which serve to admit secondary air to complete the mixture formed in the pot between the vaporized liquid fuel and the primary air admitted the inner face of the pot 5.
I5 is a flame ring having a central aperture I6. Mounted beneath the flame ring is a supplemental or recirculating ring I1, with a central aperture Ila. The outer edge of the ring I! is out upon the bottom of spaced substantially inwardly from the inner face of the pot 5, to provide an annularpassage I8. Any suitable supporting means may be employed. I illustrat for example screws I9, with spacing bushings 20. It will be understood, however, that the ring I! may be supported in any other suitable fashion. I
In the use of the device preferably a pilot flame is at all times maintained. This is maintained by providing a constant minimum flow of a liquid fuel inwardly along the pipe 8. The lowestrow of holes In serves as a primary air supply for the burner at the pilot stage. The liquid fuel flowing the combustion going on abov and mixes with the primary air entering through the lowest row of holes. This mixture burns at or above the level of the pilot ring I2. The upper rows of holes I0 provide the secondary air necessary to complete the mixture.
At higher fire, which is caused by increasing the flow of liquid fuel inwardly along the pipe 8, all of the air inlet apertures 10 may serve as a primary air supply,
pleted by the secondary air flowing inwardly and upwardly through the apertures II. The double bafile, including the rings I'KI and I1, is located above the secondary air inlets II. There is in practice a recirculation of the flnal mixture outwardly and downwardly about the outer edge of the ring IT. This recirculation takes place in the area above the secondary inlets II. Experience establishes that this recirculation tends to stabilize combustion conditions and mixing conditions at the secondary air apertures, and it holds the jets created by the inflow of air through the secondary apertures II-back against the holes through which the air flows, and prevents noise. Another result is the cleaning up of the flre and the elimination of the tendency to smoke and carbon deposit in the area above the secondary air inlets.
It will be realized that, whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disposition of parts without departing from the spirit of my inven- I the pot is vaporized by and the mixture is comv tion. I therefore wish my description and drawing to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.
I claim:
1. If: a pot type burner, a burner pot having w an annular gas recirculating passage, said supplemental baiiie having a central aperture axially aligned with the central aperture of the flame ring. v
2. In a pot type burner, a burner pot having a circumferential side wall, means for delivering a liquid fuel to the interior of the pot, the
, side wall of the pot having a plurality of air inlet apertures therein, a centrally apertured flame ring partially closing the top of the pot, and a supplemental recirculation ring mounted beneath but adjacent the flame ring, and centrally apertured in axial alignment with the axis of the flame ring, the outer edge of said recirculation ring being inwardly spaced in relation to the opposite inner face of the pot, whereby an annular circumferential recirculation passage is provided, the space between the flame ring and the recirculation ring being located nearer to the open end of the pot than the highest of the air inlet apertures, and being out of line with the line of delivery of air through any of said apertures.
3. In a pot type burner, a burner pot having a circumferential side wall, means for delivering a liquid fuel to the interior of the pot, the side wall of the pot having a plurality of air inlet apertures therein, a centrally apertured flame ring partially closing the top of the pot, and a supplemental recirculation ring mounted beneath but adjacent the flame ring, and centrally apertured inaxial alignment with the axis of the flame ring, the outer edge of said recirculation ring being inwardly spaced in relation to the opposite inner face of the pot, whereby an annular circumferential recirculation passage is provided, the space between the flame ring and the recirculation ring being located nearer to the open end of the pot than the highest of the air inlet apertures, and being out of line with the line of direction of air through any of-said apertures, the circumferential sidewall having a row of air inlet apertures extending circumferentially t-hereabout, and located closely adjacent said recirculation ring, and being adapted to direct air inwardly across the space between the outer edge of the recirculation ring and the opposed inner face of the circumferential pot wall.
