OIL BURNING HEATER Filed June '7, 1940 Patented Nov. 1s, 1941 on. BUaNlNG HEATER Boyd F. Castle, Henry Lange, and Frederick G. Suchland, Quincy, Iii.,` asslgnors to .The Quincy Stove Manufacturing Company, Quincy, Ill., a corporation of Illinois Application June 7, 1940, serial No. 339,236
12 Claims.
This invention relates to an oil burning heatery having a concentric burner with a central inspirating air inlet.
In many oil burning heaters, air is admitted at the outside which has a tendency to centralize and concentrate the heat and burning gases so that the greatest heating efficiency is not obtained. In thepresent invention this objection is overcome by providing the air inlet in the form of an inspirator at the center of the burner, causing the path of the llames and the products of combustion to pass from the center outwardly to produce an outwardly daring and spiral movement of the gases, thereby tending to throw them in contact with the outer wall or drum of the heater for quickly producing 4the desirable heating effect.
Important objects of the invention are: to provide an improved central inspirating structure for causing anoutward movement of the products of combustion; to provide an improved inspirating burner 'with a central air inlet for low ame burning conditions; to provide a central inspirating burner with parallel perforated shells in which the corresponding perforations are axially tributing ythe heat which is given olf by the drum due tothe operation of the burner.
The burner comprises a receptacle I1 having a centralv opening I8 at the bottom andan outwardly extending upper rim I9 with a flanged edge 20 secured to the inner wall of the .drum by any suitable fastening means 2I and the wall of the receptacle being spaced from the inner Wall of thev drum by the rim I9.
Seated Within the receptacle and extending upwardly from the central opening I8 is an inspirator comprising an inner sleeve 22 which substantially fits the, opening I8 and a surrounding shell 23 spaced from the sleeve to provide a ring-shaped cylindrical mixing chamber 24 closed at the top and the shell held in spaced relation by a ring 25 located below the top of the sleeve 22.
The bottom edge of the shell'is above the bottom of the pot a sufficient distance to permit v thevaporized gases to enter the mixing space aligned and proportioned to obtain the proper" gas-to-air mixture; to utilize a central inspirating air burner for throwing fiames and products of combustion outwardly for quickly and thoroughly heating the outer wall surfaces; and in general to produce the structure herein shown and described.
I'n the accompanying drawing illustrating preferred embodiments of the invention,
Fig. 1 is a sectional view of an` oil burning heater in accordance with the invention;
Fig. 2 is a detail section showing a modification ofthe burner heat delecting surface made of a plastic material; and
Fig. 3 is a sectional view of the burner showing the inspirational openings in proper alignment to produce the proper mixing of primary air.
Referring now more particularly to the drawing, a heating drum I0 of suitable sheet metal is loosely enclosed in an outer casing I I with an air space between them all around the sides and top. A discharge flue or pipe I2 extends from the drum near the top thereof through the casing and in the drum below the pipe I2 are ballies I3, having a number of openings I4 about the edge at a distance from the flue pipe and I5 having a central opening I6 out of a line with the openings I3. Any suitable means may be provided in the casing or leading from the casing for dis- 24, providing free communication from the bottom of the receptacle with the annular mixing chamber 24. Located in the sleeve and shell are a number of'rows of corresponding aligned holes or openings 2l and 28 which constitute inspira- Vtors for air from within .the sleeve 22 across the mixing chamber 24 and outwardly through the openings in the shell. The openings or perforations in the outer shell are preferably larger than the corresponding aligned openings 21 in the inner sleeve 22. At the top of the sleeve which projects above the ring 25 is another row of openings 29, and the top of the sleeve is closed by a cap or top plate 30 which extends outwardly to approximately the same extent as the shell 23 so that the openings 29 admit secondary air at the top of the burner which is deflected outwardly by the projecting edge of the top` plate and materially aids in completing the combustion and effects the clean and' clear burning of the fuel by the burner. A
For low heat and maintaining a minimum re in the burner, a flange 3l is secured to the outer shell at a point above the lower row of holes 28,
and an outer wall or deilector 32 may be positioned within the receptacle, preferably having a lower straight rim placed in alignment with the flange 3| and leaving a narrow annularspace ing the flames and gases upwardly and outwardly Y where they contact with the walls of the drum Il. V
If desired a restraining ring 35 may be seated upon the rim Il, and projecting inwardly therefrom, to deflect the names and products of combustion from the lower walls of the dnim directly above the heater.
' Fuel is'admltted to the annular bottom of the receptacle through a pipe n which extends through openings in the lower wall of the drum and of the casing surrounding it.
At the bottom ofthe drum below the burner isa baille plate I1 having a number of openings of the drum, the drum being suitably supported in the casing Il as by angle iron braces or supports 40. 1
Instead of the heatvdeector 32 being made of metal it may be composed of a plastic heat resisting material such as rebrick and if desired a unitary or sectional tlrepot of this material 4I may be substituted for the upper wall of a receptacle as shown in Fig. 2, in which the receptacle is shown with a short outer wall I3 terminating in the flange I9 at about the level of the flange 3| so that the lower edge 44 of the plastic material 4| is supported on the rim I9 providing a reduced ring-shaped neck or opening 45 for the low heat condition above the lower ring n of openings 28.
In the operation of the above described device oil is delivered to the bottom of the receptacle or potll in regulated quantity; Assuming the oil to have beenignited as by torch, match or v burning oil-soaked waste, flowing oil will be vaporized to form oil gas.
The air flowing into the receptacle through the relatively small apertures 21 and the aligned relatively large apertures 28 produces an aspirating effect or injector action which induces the flow of fuel gas into the mixing chamber 24 where it is mixed with the aspirating air and then injected into the receptacle or retort where it is burned. l
By regulation of the inflowing fuel, which regulation may be automatically controlled if so desired, the resultant fire when the burner is in normal operation may be low and function as a pilot flre or may have a greater degree varying from low to maximum or high fire at which time most`if not all of the visible ame will lie above the top of the-receptacle I1. At low fire, combustion will occur near the bottom of the receptacle I1 due to the fact that the air flowing through the lowermost row of apertures is sufficient to support combustion of the generated fuel gaswhere as at .higher stages of re where resultant combustion is raised, air owing through the lowermost or lower rows of apertures may be termed primary air in that it is insumcient in quantity to support combustion, and therefore mixes or combines with the fuel gas to form a 'combustible mixture which is later burned by air from higher rows of apertures which may be termed secondary air.- -For example, at maximum or high flame all of the aspirating air may be primary air, the visible combustion being eifected by secondary air ilowing-through the apertures 29, which, being directed radially'outward, tend to ilatten the ame as well as to mix with the combustible gas.
