'OIL BURNER Raymond W. Strawn, vista, Calif. Y Application December 7, 1937,1seria1 No. 178,523 (c1. 15s-5s) 1 Claim.
My invention relatesto that class of oil burners in which the fuel oils are generated or preheated and issue from the fuel nozzle in the form of a gas.
An object of my invention is to produce a fuel oil burner in which the generator is so constructed that it will readily gasify or generate the fuel oil, be eiicient in operation, simple in construction and more particularly be .so arranged that the generative or pre-heating member may be quickly and easily taken apart and cleaned, when tar, carbon and residue clog it up and prevent elcient operation.
The present invention, together with its objects and advantages, will be best understood from a study of the following description taken in connection with the accompanying drawing, wherein:
Figure 1 is a side elevational View of the complete improved oil burner with fuel oil container and pump attached.
Figure 2 is a longitudinal View of burner taken substantially on the line 2-2 of Figure 3.
Figure 3 is a rear end plan view thereof, illustrating certain details of the dual nozzle jet arrangement and hereinafter more fully referred to. It is taken substantially on line 3-3 of Figure 2.
Figure 4 is a sectional view of pre-heating unit or generator, showing a cross section of the four tubular channels in same, taken at 4--4 of Figure 2.
Referring to the drawing by reference numerals it will be seen that this oil burner comprises a tubular member Il Figure 2 formed in the general shape of an elongated letter W or capital M tted with bosses I2, I3, I4 and I5, which support said tubular member II concentrically within a shell or drum I6. The front end I'I of said shell is open and rear end I8 of said shell is substantially closed, except for perforations 234-34, which provide for the admission of a part of the air for combustion more fully referred to hereinafter, and tubes I9 and 20 Figure 3, which provide for the admission of generated gas to the burner as it is projected from the jet nozzles 2| and 22.
The terminals 23 and 24 of tubular member II Figure 2 extend thru holes in the closed end I8 of cylindrical shell I6 and connected to said terminals, in a gas-tight manner, are fittings 25 and 2B.
Fitting 25 is formed in such a manner that two threaded apertures provide separate openings or channels thru the tting into the upper tubular arm of member II. Threaded aperture 28 forms a direct concentric opening into'the channel of this tubular arm and provides a means of inserting, when necessary, a cleaning or ream` ing tool into this portion of member Il, for the removal of carbon and residue from tubular channel 8.
A threaded plug 2l is provided for the closing of this aperture. Aperture 29 forms a lateral passage or channel into upper arm of member II' and into this aperture is threaded the fuel oil supply pipe line 6. Fitting 26 is also of tubular construction and is formed and threaded onto lower arm of member II, at terminal 24 in such a manner that when plug 30, and attached screen 3|, are removed a direct concentric opening is provided into the lower arm of member II for the'removal of carbon and residue from tubular channel 2.
Numeral 38 Figure 2 is also a plugscrewed into a threaded aperture near the rear central portion of pre-heating member II, which aperture provides a direct opening or passage into tubular channels 3 and 'I for the removal of carbon and residue therefrom when plug 38'is removed. Therefore, by removing'plugs 2l, 30 and 38 Figure 2 the entire hollow portion of heating unit member Il, consisting of tubular channels 2, 3, 'I and 8 may be conveniently cleaned of carbon and residue, when necessary, with a suitable ream or cleaning tool.
Referring to Figure 3 it will be seen that tting 26 is also provided with two hollow arms 32 and 33, which are placed at right angles to the lower cylindrical portion, are divergent to each other, and constitute an integral part of the fitting. These arms 32 and 33 complete divergent gas-tight channels from the lower arm of the pre-heating member I I to the twin or dual fuel-jet nozzles 2l and 22 Figures 2 and 3, screwed into said arms.
Referring to Figure 3, numeral 34 indicates one of a series of perforations cut in the rear end and near the circumference of the burner shell or drum I6. The index numeral 35 Figures 2 and 3 also indicates one of a series of perforations out CII in the circumference and near the rear end of drum I6 for the admission of a controlled amount of air for the combustion of the generated fueloil gas, when it has been discharged from the jet nozzles 2| and 22 thru the mixing tubes I9 and 2 into the burner; the complete operation of which is hereinafter described.
Figure 4 is a detail sectional` View of the W shaped pre-heating member Il taken substantially on line 4-4 Figure 2, in which the numerals 8, 1, 3 and 2 indicate the channels in the pre-heating tubular member Il thru which the incoming fuel oil must pass consecutively in the process of pre-heating or generation.
Numeral 4| Figures 2 and 3 indicates a box-like depression formed in the base of the. shell or drum I6 for the purpose of retaining raw or liquid fuel oiI while it is being burned in the. process of pre-heating the generator member H preparatory to the operation of the burner.
From the above description it will be apparent that the burner operates in the following manner:
A quantity of fuel oil is placed in the supply tank, Figure 1. The tank is closed and air pressure is applied to same, by a pump or other pressure supply. A small quantity of the liquid fuel is then placed in generating pan, numeral 4I,A Figures 2 and 3, and ignited. After burning in thismanner for a few minutes, with ame passing around the pre-heating unit Ill, said unit becomes hot. Thereupon the operator opensy the control valve Figure 1,V and allows a certain amount of the fuel oil, now under pressure, to pass into and thru supply pipe 6, thence thru fitting 25, where it enters the upper and now heated channel 8 of pre-heating unit H Figure 2. The liquid fuel coming in contact with heated walls of channel 8 begins to gasify and as it progresses it reverses direction upon entering each of the consecutive channels 1, 3 and 2, moving rst towards the front and then towards the rear of burner, until finally in a highly heated, agitated and gasied state it passes from pre-heating unit Il thru screen 3l thence thru fitting arms 32 and 33 to be discharged from nozzles 2| and 22 Figures 2 and 3, thru mixing tubes I9 and 20, into the combustion chamber of the burner. Here it becomes mixed with additional air from the series of perforations 34 and 35. rlhis highly combustible gas is now ignited by the operator or by name that may remain in the generating pan 4l, and issues with considerable velocity and intense heat from the front end of burner drum at l1., where it is used for burning weeds, killngpests, disinfecting and Various other purposes, or as an industrial heating unit.
While the particular form of oil burner herein described is Well adapted to carry out the objects of the invention, the invention is capable of all such modifications and changes as come Within the scope of the `appended claim.
