4 Claims.
My invention relates to an improvement in liquid fuel burners and has for one purpose to provide a burner for liquid fuels in whicha horizontally axised pot is employed.
Another purpose is to provide aburner in which the side of a horizontally axised pot receives the fuel to be vaporized.
Another purpose is to provide improved means for gravitationally delivering liquid fuel -to a pot type burner. e
Another purpose is to provide an improved means for vaporizing liquid fuel in a hydroxylating burner.
Another purpose is to provide an improved means for feeding a liquid fuel to a pot type burner without the employment of a oat chamber or other means for maintaining a specific liquid fuel level in the pot.
Other purposes will appear from time to time in the course of the specification.
My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:
Figure 1 is a vertical section;
Figure 2 is a section along the line 2-2 of Figure 1:
Figure 3 is a section along the line 3-3 of Figure 2;
Figure 4 is a vertical section through a variant form of the device; y
Figure 5 is a similar section through a further variation;
Figure 6 is a similar section through a further variation;
Figure 7 is a. section through a further variation; and
Figure 8 is a section onthe line 8-8 of Figure 7.
Like parts are indicated by like characters throughout the specification and drawings.
Referring to the drawings, i generally indicates any suitable combustion chamber or space into which the flame from the burner is admitted or directed. It is shown as including a vertical wall 2, having a ame admitting aperture 3. It will be understood, however, that the invention may be applied to chambers in which the wall is not vertical and is not limited to a horizontally axised pot.
In the illustrated embodiment of the invention,
I illustrate the pot as horizontally axised. I illustrate a pot having a semi-cylindrical side wall 4, and a bottom wall 5, the latter being indicated as generally fiat and horizontal. The 'otherwise open end of the pot thus formed, is partially closed by a half ring B with an aperture 1 bounded by an arcuate edge 8. 'I'he wall 4 and the inner edge 8 of the ring 6 may be described about the center 9 although it will be understood that substantial variation in the shape of the pot may be made.
The pot wall 4 may be provided with an outwardly extending flange I0. The half ring 6 is continued outwardly as at II to form, in effect, a plate which is spaced from thevfront wall 2 of the combustion chamber by an upper abutment Astrip I2 and a lower abutment strip I3, having an outwardly extending flange I4, extending beneath the bottom 5 of the pot and side strips I3-a. 'I'he ange I3 serves to provide a bottom portion in which oil can accumulate to a substantial volume without flowing gravitationally out of the pot. The structure may be supported for example by a pair of tension members I5 with hooks I6 extending into apertures I1 in the wall 2, providing a readily removable support for the pot; Any other suitable means may be employed for securing the pot structure in relation to the wall 2. The semi-cylindrical member 4 is provided with a plurality of primary air inlets I8 herein shown as arranged in rows located at various distances from the ends of the pot.
I9 indicates a single row of secondary air inlet apertures, the axes of which are preferably tilted to direct the air forwardly as well as inwardly, in relation to the combustion chamber. 2l) is a liquid fuel container herein shown as having a removable cover 2|. 22 is a fuel pipe extending from the downwardly conic bottom 23 of the tank. 24 generally indicates any suitable valve structure, the details of which do not of themselves form part of the present invention. It will be understood, however, that in response to actuation of the manual control member 25, the rate of flow of the liquid fuel through the valve assembly may be varied.
I may find it advantageous to divide the interior of the burner into two parts by a generally vertical pilot half ring 35 having an aperture 36. It will be understood that when a relatively small rate of fuel flow to the burner is maintained, the pilot member 35 forms, in effect, the ame ringk of a smaller burner.
26 is a pipe elbow provided with a nozzle element 21 aligned within a union 28 apertured atone side as at 29, to permit visual observation of the rate of flow of the liquid fuel from the nozzle with the axis of the nozzle 21. Liquid fuel is permitted to ow downwardly therethrough and 30 is a vertical pipe section vertically aligned ing bottom plate 6 in Figure 1 is substantially horizontal. 'I'hus the ilow of the liquid fuel towards the forward end of the burner is somewhat hastened by gravity. I also illustrate the fuel as admitted at a level adjacent the bottom of the burner, or at the upper edge of the vaporizing plate a. I illustrate for example an inlet duct 40 controlled by any suitable valve control mechanism 4l.
In the form of Figure 5 I illustrate, as specific means for controlling the ow of liquid fuel to the burner, a oat valve assembly generally indicated as 45 and having an exterior control knob 46. Any suitable means may be employed for maintaining a, predetermined level of liquid fuel in the iioat assembly, as externally indicated by the level 41. This level is set below the upper edge of the flange I3. Thus it is impossible for suflicient oil to accumulate in the burner bottomy to flow over into the heater.
In Figure 5 I illustrate the liquid fuel as delivered to the upper edge of the vaporizing plate 5b by any suitable inlet duct or tube 48 all parts of which are below the maximum oil level 41. However, it also will be understood that I may employ a float valve assembly in which, if desired, a second liquid passage 49 may deliver liquid fuel to the forward or lower end of the vaporizing plate 5b. I may simultaneously deliver liquid fuel along both ducts, where the operator elects to connect both ducts, and I may employ an additional control member 56 for controlling the rate of flow of fuel along the duct 49.
Referring to the form of Figure 6, instead of employing a pilot member intermediate the ends of the pot I provide a main pot generally indicated at 60 with an end 6l apertured as at 62. The vaporizing bottom 63 is shown as sloping slightly toward the heater wall 2 and as terminating in a flange 64, corresponding to the flange I3 of Figure 1. 65 is the equivalent of the flame half ring of Figure l. 66 is a pilot half pot of .smaller diameter and. in effect, simply a smaller burner of the same type as the main pot 60. It may for example have primary air inlets 61 and secondary air inlets 68. The vaporizing plate 63 may, if desired, be continuous from end to end of the burner. is any suitable means, such as a float valve structure, with its control knob 1I, effective to control the rate of flow of liquid fuel along the duct 12 to the upper, outer edge of the vaporizing plate 63. When a relatively low rate of fuel flow is maintained the half pot 66 serves as a complete burner with its primary and secondary air supply adequate to vaporize and burn the liquid fuel delivered along the duct 12 to the vaporizing plate 63. As soon as more liquid fuel is delivered than can be vaporized in the member 66, the excess liquid flows into the interior of the main pot 60 and the main pot 60 begins to function. At the maximum rate of liquid fuel flow, fuel combustion takes place at or beyond the secondary inlets I9a of Figure 6 and flame will flow into the interior of the heater.
With reference to the form of Figure 7 the burner structure is identical with that shown in Figure 6 and the elements are similarly identified,
with the exception of the addition ofv a transverse i'lange or dam 'il in the general plane of the end 6l of the main pot 60. In the form of Figure 7, I employ a float valve unit 16 having two 5 control knobs 11, 18 and two liquid fuel delivery ducts 16, 60 controlled thereby. The duct 18 delivers liquid fuel to the interior of the main pot 60. The duct I0 delivers liquid fuel to the interior of the supplemental or pilot pot 66. Any
10 suitable means, manual or automatic, may be employed for controlling the flow of liquid fuel to the pots, in such fashion that, when the burner is operating under pilot conditions the liquid fuel is delivered only to the small or pilot burner 66.
15 Sufllcient combustion is maintained to keep the vaporizing plate or bottom 63 sufficiently hot so that as soon as the liquid fuel is admitted along the duct 16 vaporization and combustion begins in the pot 60.
20 It will be realized that Whereas I have shown and described an operative device, still many changes may be made in the size, shape, number, arrangement and disposition of parts without departing from the spirit of my invention and I wish, therefore, that my showing be taken as in a large sense diagrammatic.
The use and operation of my invention are as follows:
I illustrate a burner of the hydroxylating type,
in which a burner pot or half pot is employed in connection with a vaporizing surface or plate. The liquid fuel is delivered to the vaporizing surface 5, 6a, 6b, or 63 and is vaporized thereon by the heat of combustion taking place in or near the pot. It may be advantageous to tilt the vaporizing plate, as shown in Figures 4 and following, so that the liquid fuel will tend to now toward the secondary zone of the pot, and thus toward the hottest end of the burner. Primary air is delivered at the zone of admission of the liquid fuel and is effective to produce a primary mixture of air and vaporized fuel. As this primary mixture moves toward the heater, it receives the secondary air supply, through the apertures I9 or I9a and is completed and burned.
To permit efficient combustion at low fire, or at the pilot stage, with a minimum of carbon deposit, I employ the pilot element 35 or 35h in Figures 1 to 5, and the separate pilot burner 66 in Figures 6 and 7. In Figures 1 to 5 the pilot element divides the interior of the pot into a pilot chamber and a main mixing and combustion chamber. At a low rate of liquid fuel ow, all of the liquid fuel is vaporized in the pilot space.
As the rate of liquid fuel flow increases, combustion extends into the main mixing and combustion space.
In Figures 6 and 7, I illustrate a separate pilot chamber or burner which is of smaller diameter than the main burner 60 and which is connected to it through the aperture 62. In effect, part of the bottom or end 6I of the main burner constitutes an apertured flame bafile for the pilot burner.
g5 In the various forms of the device the liquid fuel may be supplied in a variety of ways. In Figures 1 and 2, I illustrate the fuel as delivered through an upper part of the burner, and, preferably, into a pilot area partially dened by the member 35. In the remaining forms of the device I illustrate the liquid fuel as delivered adjacent the vaporizing plate which forms the effective bottom of the burner. In all forms, however, the liquid fuel may flow along or spread out on the vaporizing plate and is subjected to and mixed with the primary and secondary air which ows through the primary and secondary air inlet apertures.
In the form of Figure 7, I illustrate separate liquid fuel supply means for the pilot burner 66 and the main burner 60. I obtain the same result in the form of Figure 5 by employing two ducts extending to a single burner member which is divided by the intermediate element 35h into primary and secondary chambers.
In all the forms of the device herein shown liquid fuel is ldelivered at such a point on the vaporizing plate that it flows forwardly toward the flame discharge aperture of the burner. Thus the fuel, in the course of its vaporization, ows from the coolest to the hottest part of the burner. This is an important factor in connection with adequate vaporization, avoidance of carbon deposit, and eiciency of combustion.
