JOHN P. SWIFT, OF WVOODS I-IOLL, MASSACHUSETTS.
APPARATUS FOR BURNING HYDFiOCARBON OIL AS FUEL.
SPECIFICATION forming part of Letters Patent No. 431,237, dated July 1, 1890.
Application filed October 3, 1889. Serial No. 825,855. (No model.) i
To all whom it may concern.-
Be it known that I, JOHN P. SWIFT, of Woods Hell, in the county of Barnstable and State of Massachusetts, a citizen of the United States, have inventedcertain new and useful Improvements in Apparatus for Burning Hydrocarbon Oil as Fuel, of which the following is a specification.
My invention relates to apparatus for burning hydrocarbon oil, and especially crude petroleum, as a fuel to supply heat for making steam or other desired purposes.
In the accompanying drawings I have represented an apparatus in which my present improvements are embodied in the form now best known to me.
In the drawings, Figure 1 is an end view, and Fig. 2 a vertical longitudinal section, of such an apparatus. Fig. 3 is a similar view of the apparatus as set up in connection with a steam-boiler of a well-known type.
In the drawings, A represents an initial combustion-chamber, the bottom of which is preferablyformed of a pan B. The bottom of this pan may have a covering of asbestus, mineral wool, or other substance such as has heretofore been employed in devices of this character. Oil is fed into the combustionchamber by a suitable feed, preferably acting by gravity, as shown at O, and is ignited therein in any well-known manner. Oxygen to support the necessary combustion in the chamber A is admitted through an air-opening a leading thereto. This air opening in practice should be provided with a suitable damper to regulate the amount of air supplied. The oil ignited and burning in the chamber A gives off vapor or gas, and an outlet D, preferably circular in form, as shown, is provided in the chamber A, through which outlet the gas or vapor may pass on its way to the work. To complete the combustion of the vapor or gas formed in the chamber A, I provide an airpipe E, preferably arranged as shown, the outer end of which communicates with the outside air or other source of oxygen. This air-pipe enters the chamber, and its inner end is arranged substantially opposite the outletopening D, but at a distance therefrom suflicient to leave room for the passage out of the vapor. This air-pipe being thus located opposite the outlet discharges a supply of air centrallyinto the body of the vapor as it leaves the vaporizing-chamber, so that the vapor of the oil and the oxygen coming through the passage-way E will be brought into thorough contact.
Beyond the outlet D a second pipe F, preferbly arranged as shown, is provided, which serves to hold the oxygen and oil-vapor together and to intermix them as they pass through it to the point where the work is to be done, which in Fig. 3 I have represented as the fire-box of an ordinary horizontal tub ular boiler.
The apparatus thus far described has been found in practice to give commercially good results; but at the same time it is d efective in that there is a tendency to the deposition of carbonaceous matter in the form of soot around the edges of the outlet D, and also along the walls of the pipe F. This deposit, if it i11- creases sufliciently, will interfere with the most effective working of the apparatus; but its formation around the edges of the outlet D may be obviated by the use of an additional air-supply, as through tubes G G G, communicating at one end with the atmosphere, and with their inner ends so located that air passing through them shall be supplied to the outside of the mass of vapor as it passes out annularly between the interior body of air supplied through the pipe E and the exterior envelope of air supplied through the pipes G G G.
In addition to the air-supplies already mentioned,a third may be'provided, entering the pipe F at or near its end next the outlet 13, and such an air-supply is shown at H. The introduction of air at this point is found to check the tendency to deposit soot upon the inner walls of the pipe F. The various airinlets should in practice be provided with suit able regulating-dampers.
I claim-- 1. In an apparatus for burning hydrocarbon oil, an ignition-chamber A, an air-supply a thereto, an outlet D from said chamber, a main air-supply pipe entering the said chamber and terminating opposite the said outlet, a pipe F outside the said chamber, the said pipe having one extremity opposite the said outlet and leading to the point where the products of combustion are to be discharged, and a suitable oil-supply whereby oil may be fed into the chamber, substantially as set forth.
2. In an apparatus for burning hydrocarbon oil, an ignition-chamber A, an air-supply a thereto, an outlet from said chamber, a main air-supply pipe entering the said chamber and terminating opposite to the said outlet, an additional air-supply arranged around the said chamber, as described, whereby air may be discharged upon the outside of the vapor passing from the said outlet, a pipe F outside the said chamber, the said pipe having one extremity opposite the said outlet and leading to the point where the products of combustion are to be discharged, and a suitable oilsupply whereby oil may be fed into the chamber, substantially as set forth.
3. In an apparatus for burning liquid hydrocarbon, a chamber A, provided at its lower part with a suitable liquid-fuel receptacle B,
an air-supply a to said chamber, an outletorificeD from said chamber, amain air-supply pipe E, extending across said chamber and terminating opposite to the said outlet, a series of additional air-supply pipes G, arranged around said chamber, as described, a pipe F, having one extremity opposite the said outlet D and leading to the point Where the products of combustion are to be discharged, air-passages for supplying additional air to said pipe to mingle with the air and vapors coming from the said chamber A, and a suitable oil-supply pipe 0, whereby oil may be fed into the chamber, substantially as set forth.
In testimony whereof I have hereunto subscribed my name this 23d day of September, A. D. 1889.
JOHN P. SWIFT.
