FIG.2
Patented Aug. 17, 1937 PATENT orrlca 2,090,568 METHOD or on. ammo Robert F. Andler, Rutherford, N. 1., assignor to Elcctrol Incorporated tion of Delaware Clifton, N. J., a corpora- Application December 29, 1936, Serial No. 118,081
3 Claims.
It has been found in practice that it is extremely diflicult to obtain proper combustion in an oil burner of the gun type. If it produces the so-called horsetail type of flame, a considerable amount of asphalt is deposited on the walls of the combustion chamber of the furnace. While if it is of the whirling type there is a great likelihood of more or less unburned oil escaping unconsumed.
The object of my invention is to provide a method of burning oil which will insure a more nearly perfect combustion than can be secured where either of the above types of burner is employed.
A further object is to provide a method which will cause the entire surface of each particle of oil to be brought into contact with the flame.
A further object is to provide a method which will propel and direct the mixture of oil and air outwardly from the nozzle in a gyrating conoidal outwardly flaring vortical annulus having a region of reduced pressure whereby a vortex is formed adjacent its axis which will cause said gyrating mixture to turn inwardly.
I have discovered that by providing a tube of large diameter 5" or more that it is possible to compress the forced air draft into a gyratory current in the form of an annular lamina and by discharging it so that it will create a partial vacuum in its center, the air current will turn inwardly a short distance from its point of egress with the result that the minute globules of oil are caused to rotate on their axes bringing the flame into contact with the entire surface of the giebule of oil with the result that a more nearly perfect combustion can be attained.
In the accompanying drawing which is hereunto annexed and is a part of this specification, I have shown a concrete form of apparatus which will carry out my improved method.
The drawing is furnished solely for illustrative purposes and is not to be considered in a limiting sense, for it will be clear, to persons skilled in the art, from the hereinafter contained description that numerous forms of apparatus may be utilized, all of which will employ the steps of my method.
My means of accomplishing the foregoing objects may be more fully comprehended by having reference to the accompanying drawing, which is hereunto annexed and is a part of this specification in which:
Fig. 1 is a front elevation of an oil burner partly in section, constructed to employ my method;
Fig. 2 is a side elevation of the same, a portionbeing broken away to show the interior construction;
Fig. 3 is a fragmentary detail view showing the entrance part for the air current; and 5 Fig. 4 is a front view of the same.
Similar reference numerals refer to similar parts throughout the entire specification.
As shown in the drawing, an electric motor is connected to a blower fan 2 of standard con-' 10 struction. The exhaust part 3 is connected to an inlet 4 which leads tangentially to a cylindrical chamber or sleeve 5. A tube 6 extends axially of the chamber 5 and conveys the oil to its point of discharge, 1. 15
The inlet 4 is important as it should be shaped not only to direct the air tangentially into the chamber 5 but it must form it into a lamina directed against the end wall 8 of the chamber 5, this causes the lamina to assume a gyrating mo- 20 tion, as clearly indicated by the dotted lines in Fig. 2. This gyrating lamina of air hugs the inner wall of the chamber until it reaches the nozzle 9.
The nozzle 9 is formed of two inwardly taper- 25 ing truncated cones l0 and II which are spaced from each other forming an annular space I 2.
The result of this construction is that the gyrating lamina of air will be compressed and discharged in an outwardly flaring conoidal -an- 30 nulus which will produce a vortex in its center, with the result that the air will be turned inwardly as clearly seen by the dotted lines in Fig. 2. i
The oil is sprayed from the end of the tube 8 35 into the gyrating conoidal annulus of air and due to its movement each minute globule of oil is constantly and continuously rotated with the result that when the mixture is ignited, the flame contacts the entire surface of each of these 0 rapidly revolving globules of 011, instead of only reaching one side of-them, as a result, I obtain almost complete combustion.
In some instances it may be found desirable to mount a vaned disc l3 on the tube 6 to assist in 45 forming the air current into lamina. It may also in some cases be found desirable to have the vaned disc l3 rotatable upon the tube 6. Obviously such changes are structural features and in no way change the steps of my improved method. 50
Having described my invention, what I regard as new and desire to secure by Letters Patent is: 1. The method of combustion comprising the following steps, directing and propelling air into and through a cylindrical chamber in the form following steps, directing and propelling air into and through a cylindrical chamber. in the form of a gyrating annular lamina current, discharging the air from said chamber, spraying oil into said air current adjacent the place oi. discharge, said mixture of oil and air forming a gyrating conoidal outwardly flaring vertical annulus having a region oi. reduced pressure, whereby a 20 vortex is formed adiacent its axis which will cause said gyrating mixture toturn inwardly beyond the place where mixture occurs and cause rotation 0! the globules of oil in the mixture, and then igniting said mixture, whereby the entire surface of each of the globules of oil is brought into contact with the flame.
'8. The method of combustion comprising the following steps. direcflng and propelling air into and through acylindrical chamber in the term or a gyrating annular lamina current, discharging the air from said rueiinto said aircurrent adiaunt the place oi discharge. said mixture or fuel and air forming a gyrating onoidal outwardly flaring vertical annulus having a region or reduced pressure. whereby a vortex is formed adjacent its axis which will cause said gyrating mixture to turn inwardly beyond the place where mixture occurs.
