ROBERT W. WIELDERWAX, OF ATLANTIC CITY,
NEW" JERSEY, ASSIGNOR TO GEIST MANUFACTURING COMPANY, OF ATLANTIC CITY, NEW JERSEY, A CORPORATION OF DELAWARE.
PROCESS OF BURNING LIQUID FUELS.
Application filed March 8, 1923.
To all QUIZ-0771' it may concern:
Be it known that 1, ROBERT /VAL'roN iVIEoERwAx, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented certain new and useful improvements in Processes of Burning Liquid Fuels. of which the following is a specification.
This invention relates to processes of burning liquid fuels, such as kerosene, gas oil, and the still heavier fractions of petroleum, which as commonly burned for heating boilers, melting metais, and the like, produce carbonaceous particles whose presence in the products of combustion render the use of such fuels unsatisfactory for some purposes. Aside from the loss in efficiency due to the fact that the combined carbon. in the liquid fuel is not wholly consumed, the presence of carbonaceous particles in the products of combustion is disadvantageous by reason of the smoke produced, and it is particularly disadvantageous in heating and melting furnaces of the type wherein the products of combustion come into direct contact with the material to be heated or melted as, for example, in melting glass or maintaining it in molten condition.
This application is a continuation, in part, of my co-pending application relating to process of burning liquid fuels, filed November 2, 1922 Serial No. 598,693.
So far as I am aware, prior to my invention, there was no method of or apparatus for so burning liquid fuels of the character above referred to for industrial purposes, as in furnaces or the like, that the products of combustion are substantially free from car bonaceous particles.
Now I have discovered a method of so burning liquid hydrocarbons and particu- .larly the less volatile petroleum fractions obtainable at a relatively low cost, that their fuel value is more eiiiciently utilized than in methods and apparatus heretofore used and the products of combustion are not only substantially free from the presence of carbonaceous particles, but so almost entirely free from unconsumed carbonaceous particles that, for the first time in the history of the art, such products of combustion may be used for melting glass or maintaining it in molten condition by contact therewith, without injury to the glass,
Serial No. 623,724.
In my process, the oil is first heated to a point somewhat, and preferably, just below its point of vaporization under the pressure to which it is exposed, and is then suddenly heated to a point above its point of vaporization, and in the preferred practice of my invention, to a point greatly above its point of vaporization under the conditions present, whereby it is partially or completely flashed or rapidly transformed into an aeri form condition, and then mixed with some aeriform fluid, such as superheated steam or highl heated air, adapted to complete the transformation of the fuel into an aeriform condition and to facilitate or support the combustion of the vaporized fuel. The mixture is then burned in free contact with the air, preferably in the form of a rapidly moving current or jet issuing from a suitable pipe or nozzle by means of which the flame produced may be directed to the point at which the heat of the burning fuel is to be utilized.
In the preferred practice of my invention, the fuel when first heated to a point somewhat below its point of vaporization is maintained under pressure so that its point of vaporization is above its point of vaporization at atmospheric pressure. This preheated liquid is then suddenly heated to a temperature above the point of the Vaporization of the fuel under the conditions present.
I prefer to effect the rise in temperature to suddenly and completely transform the fuel into aeriform condition by contacting it with a highly heated surface and mixing it with some aeriforn'i fluid as superheated steam or highly heated air. To facilitate rapid vaporization or flashing of the preheated liquid fuel into aeriform condition, I prefer to contact it with the highly heated surface and mix it with some aeriform fluid as superheated steam or highly heated air under conditions permitting of its rapid expansion, as in-an expansion chamber. The rapid expansion of the fuel at the instant of contacting it with the highly heated surface and of mixing it with some aeriform fluid as superheated steam or highly heated air will facilitate the fuel attaining a form in which it will burn without the production of unconsumed carbonaceous particles.
in the accc npanying drawings, I have Referring to the drawings, the reference numeral 1 designates a furnace wall. This wall is provided with an opening for the re ception of a burner casing and the burner casing is arranged therein in the usual manner. The burner casing consists of an inner cylindrical member 2, having a flange 3 formed on it forward end. A cylindrical member 4 is arranged at the front end of the casing and spaced therefrom, forming a chamber 5 for heating air, steam or other fluid to be employed in vaporizing and burning the fuel. The rear portion of the burner casing is surrounded by another cylindrical member 6 which is spaced therefrom, forming a preheating chamber 7. The adjacent ends of the cylindrical members 4, and 6 are provided with flanges 8 and 9, forming end walls which are secured to the casing in any suitable manner, as by welding. The rear of the cylindrical member 6 is provided with an inclined portion 10 and a portion 11 contacting with the burner casing. This rear portion may be secured to the burner casing in any suitable manner, to form a gastight chamber.
Air, steam or other fluid, is delivered to the heating chamber 5 through. a. pipe 12, and highly heated air. superheated steam or other fluid is fed therefrom through a pipe 13. Oil is delivered to the preheating chamber through a pipe 1A and the heated oil is conveyed therefrom through. a pipe 15. A burner pipe 16 is arranged within the burner casing. This burner pipe is of greater diameter than the feed pipes 13 and 15. and is connected to a pipe 17 of substantially the same diameter as the feed pipes, by means of a fitting 18. A valve casing 19 is arranged at the rear of the pipe 17. having a valve 20 therein, controlled by a handle 21. As shown, the fluid pipe 13 communicates with this valve casing. A fitting 22 is arranged in the adjacent end of the pipe 17 and this fitting is provided with an opening for the reception of a pipe 23 of smaller diameter through which air. steam or other fluid is adapted to pass. As shown, the forward end of this pipe is reduced. as at 24, and is provided with a relatively small outlet opening.
The oil pipe 15 is connected to a valve casing 25 having a valve therein (not shown) controlled by a valve handle 26. The opposite end of the valve casing is connected to a rearwardly inclined pipe 27 forming a part of the fitting 18. This pipe is provided with a relatively small opening 28, leading into the fitting to permit communication between the oil pipe and the burner'pipe. A nozzle 29 is arranged on the forward end of the burner pipe, being secured thereto by a fitting 30.
The flame from the nozzle 29 is projected into the fire box of the furnace and the heat therein is sufflcient to heat the forward end and inner surface of the tube 2 to a very high temperature.
In the preferred practice of my process, steam or air is delivered to the heating chamber 5 through pipe 12, and oil under pressure is delivered to the preheating chamber 7, through pipe 14. The steam delivered to the heating chamber, when steam is employed in the fuel mixture, is superheated to such a. temperature that it eXpandsmaterially in volume. Its temperature is ordinarily around 700 F. The air delivered to the heating chamber, when air is employed in the fuel mixture, may be heated to a much higher temperature than when steam is employed. The oil is heated to a relatively high temperature in the preheating chamber but is not vaporized. At the pressure employed in practicing the process, the
till
oil. is preferably heated to a point just below vaporization. The superheated steam or highly heated air is delivered through pipe 13 to the inner pipe 23 and thence to the burner pipe 16. Oil passing through pipe 15 is delivered through the opening 28 against the highly heated surface of the pipe 23. When the oil enters the burner pipe, which is of greater diameter than the pipe 15. it tends to vaporize. This tendency is materially increased by contact with the hot surface of the pipe 23 and by mixing with the superheated steam or highly heated air issuing from pipe 23, and complete vaporization or gasification takes place almost instantly.
While I have described in detail the preferred practice of my process, itis to be understood that the details of procedure may be widely varied without departing from the spirit of the invention or the scope of the subjoined claims.
