' (ou. 15s-sii My invention relates to an improvement in pot type burners and has for one purpose to provide improved means for delivering air to a liquid hydrocarbon burner. Another purpose is to provide improved means for supplying secondary air to the mixture of vaporized hydrocarbon and primary air, in a hydroxylating, pot type burner. An other purpose is .to obtain silent combustion. Other purposes will appear from time to time in the course of the specification and claim. I
This invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:
Figure 1 is a vertical axial section of an embodiment of my invention;
Figure 2 is a section on the line 2-2 ure 1. I 4
Like parts are indicated by like symbols throughout the specification and drawings.
Referring to the drawings, i generally indicates an outer housing having a plurality of feet 2 between which are air inflow spaces 3. The housing is partly closed by a horizontal partition t centrally apertured as at E. t is anangle ring which receives .the upper outwardly extending flange 8 of a burner pot l. e indicates an upper portion of the housing l, which serves as a cornbustion chamber, or a heat radiating member. Any suitable draft means. not herein shown, may heated gases and by-products of combustion. One'end of the pot is partially closed by a centrally apertured flame ring iii. The pot is shown as having a slightly of Fisconcave bottom or closed end il and a generallycylindrical side wall i2 provided withv a plurality of primary air inlet apertures it, circumferentially spaced about the wall i2 and located at various distances abovefthe pot bottom. Located above. or beyond the lowest oi .the primary air inlet apertures i8 is a centrally apertured pilot bams ring ld supported on any suitable pins or supports i5. A liquid fuel is supplied to the pot along the pipe i6, the rate of flow being controlled by any suitable control means generally indicated as il. I illustrate, for example, a blown type oi' iloat valve assembly with a manual control knob Id for controlling the flow oi fuel along the pipe it. However, it will be understood that any suitable control means, manual or automatic. may be provided for varying the rate of flow of liquid fuel along ythe pipe i6 or for maintaining a uniform rate of ilow, when a uniform rate is desired. It will b e understood that whereas I have shown a vertically axised pot, the pot may be horizontally dll dit
axised or the axis may be variously inclined in relation to the vertical.
It will be understood that in pot type burners oi the present type, a liquid hydrocarbon is vaporiaed by the heat oi combustion taking place in or above the pot. The liquid hydrocarbon is admitted to the interior of the pot and-is initially partially vaporized by the heat of hydroxylation taking place in the pot. As the liquid hydrocarbon is vaporized in the pot it rises and is surrounded by a nlm of secondary air. The radiantI heat from the ensuing complete combustion supplies the remainder of the additional heat neces sary to vaporlze all of the liquid hydrocarbon. There is a differentiation in 'act-ion between the so-called primary air and the so-called secondary air admitted to the interior of the pot. With reference to the present structure, the air entering through the primary apertures i3. has a. different action than the air entering through the secondary apertures i9 or 20. All of the oxygen in the air entering through the primary apertures it is fully'consumed in the process of hydroxylation.
The oxygen in the air entering through the secondary apertures is only partially consumed. but all of the vaporized hydrocarbons surrounded by the secondary air are entirely consumed.
when fuel is being supplied lto the pot for a high lire, combustion takes place at a level de' fined by an imaginary surface at the confluence of the air delivered through the apertures i9 andv 2@ oi Figure l. The flame iiows through the cen- -tral aperture oi the flame ring i@ and into the combustion chamber il.
The present structure provides a particularly emcient means for supplying the secondary air and for providing a silent and emcient combustion. I employ, for example. two rows of secondary air inlets it and 2B. Each such row, in the iorm of Figure 1. is shown as formed bystrik- .me in the metal of which' the pot is 'roi-med te The deflectors il.
provide guides or defiectors. of the upper apertures i9 direct the air downwardly and linwardly into the pot. The dodectors 32 oi the lower row of secondary air inlet apertures 2s direct the air upwardly and in-l wardly into the pot. Preferably the deiiectors are arranged in pairs asshown in Figure i, in such fashion that the jet of air downwardly directed from each guide 2i meets the jet oi air upwardly directed by the corresponding guide 22.
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 ot parte `iashion y prevented. Itis important that the secondary air the ture Y the air enters.
In a burner pot for member havin: a generally cylindrical cireum` without ldeparting fron; the spirit or my'invention. I'thereiore wish my drawings and descripmy precise showing. y The use andopcration of the invention are as follows: K f l In\pot type liquid hydrocarbon burners .it is hly :ilgsecondary air to a primary mixture in such a that combustion noises are substantially be provided in such quantities and at such location that the ilnal mixture will burn steadily clear back to the wall of the pot. or to some other iixe'd plane or surface near the point otadmlsslon oi' secondary air supply. In the present stmothe secondary air is supplied ln imbinsing jets which engage at a short distance inwardly `from the wall of the pot and which provide an ample supply oi' secondary air at the point oi vides quiet and eilicient combustion. with an-axnple supply of air at the speed of ilow of the iinal iet and prevents any tendency for the final ,iet to b urn away from. the inner face oi' the pot. Thus I obtain the ad- .vantase of the admission oi the air vat a relatively low rate and of the provision of an ample sup.- ply of air at the base oi the secondary Jet.
A primary cause of noisy combustion is the tendency of the base of the ilame to leave the immediate vicinity of the orifice `through which By providing impinging .ietsl I control or limit the speed of the air Jet ilow, and at the sametimevinsure an ample supply of secondary'air at the base o1' the name, adjacent the inner face of the pot wall.
I. claim:
pot type burners, `a pot ferentiai wall and a closed end, the other end oi the pot being open. said circumferential wall important to provide an adequate supply lovthe corresponding inlets of the two rows being 20 admission. In practice th'e form o! Figure 1 probase o! the Jet. The inipingement of the two inclined jets holds down the g.
4 `having a plurality of primary air inlet apertures circuinierentially spaced thereabout and located at various distances from the closed end, said potwall having two circumferentially extending rows o! secondary air inlets located acliacent the open end, the inlets oi the row nearest the openl endof the pot being inwardly inclined toward the closed end, the inlets :of the other secondary row being inwardly inclined toward the open end,
positioned `and adapted to deliver impinging jets of air into the interior oi the pot,`and means for delivering a liquid fuel to the interior oi the pot, each such secondary air inlet having alizned w therewith a directing portion of the pot wall,
oiset inwardly from the side wall of the pot. the inner edges of said inwardly oiset 'directing portions assisting in deilning the inlets associated therewith.
