Specification of Letters Patent.
Patented Dec. 23, 1913.
Application led November 10, 1.910. Serial N e. 591,664.
To all whom t may concern:
Be it known that I, GEORGE W. MCGAL- LEN, a citizen of the United States, residing at 1Wheatland, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Oil- Burners, of which the following is a specilication.
This invention relates to oil burners, and in the adaptation shown, is primarily intended for use in producing a forge fire.
One of thenobjects of my invention is the provision of an oil burner in which heavy low grade oil is used in connection with a fan blast. f
A further object of my invention is the provision of internal baHle rings and the arrangement of the burner that'will effect a thorough atomization of the oil in intermixture with the air blast.
Further objects and purposes of my invention will appear from the drawing, the speci- Hcation describing the same, and the claims appended thereto, in which is fully set forth the arrangement' of parts, combination of elements, and specific structural details.
properly comprised within the scope of the same.
Figure 1 is a side cross sectional view of the air Hue and lmixing chamber showing a crossl sectional view of the burner proper and oil feed pipe. Fig. 2 is a cross sectional view of the Hue and burner taken on the line A A of Fig. 1 and looking in the direction of the air How.
Referring now to the two figures in which like reference characters designate like parts, (1) represents the air Hue and mixing chamber which is cast integral with the Hange portion (2). rIhe Hue is adapted to be secured to the furnace wall by bolts passing through the apertures (3) in the Hange (2) so that the short forwardly projecting end of the Hue extends into the furnace. The
Hue shown is IL shaped with the unmixed air v coming` downA the vertical leg. On this portion of the Hue at (4:) I provide a blast gate casting (5) in which the air blast issuing from (6) is regulated by the blast gate (7). That portion of the Hue projecting into the furnace is provided with an interior annular baHle 8), the purpose of which will be more fully set forth hereafter. Centrally of the diameter of the horizontal portion of the Hue and on the outer side of the elbow, I provide a port, cast with the Hue and interiorly threaded to receive the rear end of the oil feed pipe (10). Interposed between (10) and the oil feed pipe (12) is a suitable hand valve (11) by which the How of oil into the burner is regulated. The forward end of the oil pipe (10) is provided with a choked nozzle (13) having an oil port (14) therein, and the exterior of this end of the pipe is threaded to receive the spider bar (15). Suitably secured to the outer ends of the spider, preferably by bolts and nuts (18, 20) is the rear flange portion (17) of the mixing cone (19). The forward "part of this cone 1s provided with an interior annular battle (21), the interior face of the baHle ring'being threaded as at (22).
In operation, the air coming down the vertlcal leg 'of the Hue is drivenA by a fan, not shown, while the oil, under a four to ten poundpressure, issues 'from the port (14).
The rear diameter of the mixing cone is preferably about three-fourths of the interior diameter of the horizontal leg and thus takes in the greater part of the an' current to catch up the oil. That portion of the air current within the mixing cone and farthest 'removed from the oil port is caught at the forward part of the cone by the annular baffle and thrown across the central current of air and oil. The baiile ring being threaded, provides a rough surface against which the broken current of air and oil is now thrown, thus assisting in the intermixture and allowing the mixed oil and air to issue in a spray from the mixing cone. The
atomized oil is now carried forward surrounded by an unmixed air current toward the front portion of the mixing'chamber where the outer air'soon strikes the annular baffle (8) and is thrown across the main current thus giving a highly mixed current of air and atomized oil, the structure of which current, however, contains the heavy oil vapor in the interior of the current.
4In, practice, I have found it possible to produce a highly eficient atomization of the oil with merely a fan blast roviding only a six ounce pressure where a burner and mixing chamber constructed in accordance with the foregoing description is used. In the particular construction of my burner and arrangement of the Hue and burner, I can produce a higher combustible intermixture of oil and air'using only a fan blast and low grade oil, than can be equaled by other burners using a high blast pressure as pro-- medium grade oil.
duced in blowers together with a highY or I have found in practice that this is accomplished by providing the interior annular battles in the forward part of the mixingcone and the forward part of the flue which serves as a mixing chamber, and also by roughening the interior of the baie ring on the mixing cone which in the adaptation shown and described is threaded.
I am aware of the prior art in burners using burners and mixing chambers with reduced and conical shaped nozzles, but in my burner I not only accomplish the results obtained in these otherburners, to wit, converging the outer air current toward the inner air current and affording an expansio-n of the mixture as it leaves the nozzle end, but in using an interior baille ring having 'its inner face abruptly angled against the air current, I produce a highly etlicient breaking of the air and oil molecules andi consequently more intimate intermixture of them.
I claim;
1. In an oil burner the combination of a mixing chamber, said mixing chamber having a mixing cone concentrically suspended therein, said mixing cone having a ring interiorly located in the forward converging end of the cone, said ring presenting an abrupt angle to the air current passing through said cone, the inner surface of said ring being threaded to afford resistance to the current passing through said ring, and means for supplying air to said cone and chamber and oil to said burner, substantially as shown and described.
2. In an oil burner the combination of a tubular L shaped casting,
flue and a mixing chamber,
comprising an air an oil feed pipe entering the outer side of the elbow and projecting centrally of the horizontal leg of the casting, a spider secured to the forward part of the oil feed pipe, a mixing cone secured at its larger end to the spider surroundingy the forward end of the oil feed pipe, a baille ring, located interiorly of the forward part of the mixing cone, having its inner surface roughened, and means for supplying air to the flue, substantially as shown and described.
3. In an oil burner, the combination of a tubular L shaped casting having a mixing cone suspended cent-rally of the interior of the horizontal leg, a baille ring, having its inner surface roughened, located interiorly of the forward part of the mixing cone, and an interiorly located annular baille at the forward'part of the horizontal leg of the casting, substantially as shown and described.
4. In an oil burner, the combination of a tubular casting having a mixing conecentrally suspended therein, a battle ring, having its inner surface roughened, located interiorly of the forward part 0f t-he cone, means for supplying air at the rear of said casting, so that part of the air entirely surrounds the mixing cone and part enters its rear, and means for supplying oil at the central rear part of the cone, whereby an air current is thrown across the line of oil againstthe roughenedsurface of the cone ring, substantially as shown and described.
In testimony whereof I have affixed my signature in presence of two witnesses.
GEORGE W. MCCALLEN.
