HYDROCARBON-FURNACE.
SPECIFICATION forming part of Letters Patent No. 782,774, dated February 14, 1905.
Application filed March 5, 1903. Serial Nol46,369.
To all whom it may concern:
Be itknown that I, GEORGE C.CALENTINE, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Hydrocarbon-Furnaces; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
My invention relates to a furnace designed more particularly for burning liquid hydrocarbons; and it has for its object to provide for the vaporization of the hydrocarbon and its mixture with heated air and the subsequent impelling of the mixture of heated air and vaporized oil into the furnace.
T0 the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the construction as well as in the combination of parts hereinafter particularly described and then sought to be clearly'defined in the claims, reference being had to the accompanying drawings, forming a part hereof, in which Figure 1 is a side view, partly in section, of a boiler-furnace embodying my invention. Fig. 2 is a plan view, partly in horizontal section, of the furnace; and Fig. 3 is a cross-section through the heating-drum. Fig. 4 is a section through a portion of the vaporizing manifold or coil, showing the coiled strands or wires in the same.
In the drawings the numeral 1 designates thefire-box, 2 the bridge-wall, 3 the gratebars, 4 the front wall provided with the dooropening 5, leading from the ash-pit 6, and with the door-opening 7 at the front of the fire-box, while 8 represents a tubular boiler provided with the smoke-stack 9, all of which parts may be of the ordinary construction and of any approved form.
Within the upper portion of the smoke-stack drum a pipe 1 1 leads to the inlet of an exhaust fan and blower 15, and from the discharge 16 of this fan two branch pipes 17 lead to opposite sides of the fire-box and discharge into the fire-box, one at each side and preferably at the forward portion of the fire-box next to the front wall 4: thereof. For a onehundred-horse-power boiler I prefer that the heating-drum 10 shall have a heating-surface of about one hundred and twenty square feet and that the pipe 14, leading therefrom, shall have a diameter of about nine inches and open into a nine-inch inlet to the exhaust fan and blower and that said exhaust-fan shall have a capacity to furnish about fourteen hundred cubic feet of air per minute, the pulley 18 of the fans blade-shaft having a diameter of about five and one-eighth inches with a fourinch face and capable of sixteen hundred revolutions per minute, and the two branch pipes 17, which lead from the nine-inch discharge 16 of the exhaust-fan, I prefer to make about six inches in diameter each. While the dimensions given are those which are preferred, still variations can be made therein without departing from the features of the invention.
In each of the branch pipes 17 at the sides of the fire-box I provide a wire-gauze partition 19 of about four hundred meshes per square inch, so as to break up or dififuse the blast mixture, composed of the heated air and vaporized oil, so that the same will be blown into the fire-box in a finely-diffused state, and in each pipe back of the wire-gauze partition I provide a gate 20 for regulating the blast. For the purpose of vaporizing the oil I provide any desired number of coils 21, located so as to be under the influence of the heat in the fire-box, so that the oil will be vaporized in the coil, the vaporized oil passing thence to a mixing-chamber, where it is mixed with the heated air drawn from the drum in the smokestack, after which the mixture of heated air and oil-vapor is impelled into the lire-box for generating and maintaining the heat desired. In the drawings 1 have illustrated a number of the vaporizing-coils 21, placed side by side in an opening formed in the front wall of the fire-box, each coil being made up of sections of one-inch pipe connected at alternate ends by return-Ls, the upper portions of the coils being connected with a header 22, into which the hydrocarbon is led through a one-inch pipe 23, leading from a supply-tank suitably located, said pipe being provided with a controlling-valve 24:, while the lower portions of the coils connect with a header 25, from which leads a pipe 26, preferably one and one-half inches in diameter, said pipe receiving the oilvapors and connecting the same to the pipe 14:, which leads from the heating-drum 10, the connection of the vapor-pipe 26 with said pipe 14 preferably being adjacent to the inlet of the exhaust-fan 15. The pipe 1 at the point where the vapor-pipe leads into the same constitutes a mixing-chamber in which the heated air and oil-vapors are thoroughly mixed and from whence they are drawn into the fan and by the fan impelled in their mixed state through the branch pipe 17 and'into the firebox at opposite sides thereof, thus supplying the fuel for maintaining combustion in the fire-box.
' If for any reason it may be desired to lower the temperature of the heated air drawn from the drum 10, the same can be done through the instrumentality of an air-regulating valve or damper 27, located in the pipe 14, it being preferred to locate said valve 27 at such point in the pipe 14 that the air for cooling purposes may be admitted into the pipe previous to the mixture of the heated air and oil-vapor, although I am not restricted to such location so far as other features of my invention are concerned.
Under the invention described the liquid hydrocarbon is thoroughly vaporized before being injected into the fire-box and is also mixed with air of the desired temperature before being injected into the fire-box, and as a result the fuel for generating the heat and composed of a mixture of oil-vapor and air is in the best possible condition for immediate complete combustion and utilization of the greatest number of heat units at the time of being injected into the fire-box. Furthermore, the oil-vaporizer and the heating-drum are located to the best advantage for economy and for the results to be attained, and all the parts are under the easy control of the attendant. It will be observed that only a portion of the opening 7 in the front wall 4 is occupied by the vaporizing-coil, thus leaving the remaining portion of the opening for use in the introduction of other fuel in first starting the furnace and also adapting the furnace to be used either for burning liquid hydrocarbons or solid fuels, as may be desired, under circumstances as they may exist at the time. It will also be understood that doors may be provided to the openings in the front wall without interfering with the other parts illustrated.
l have illustrated and described what I consider to be the best construction and arrangement of parts for the objects in view and also have given the preferred dimensions of'the parts; butit is to be understood that changes can be made therein and essential features of my invention still be retained.
Within the vaporizing-coil there is placed a number of wires 28, twisted together into the form of a loose cable, said wire practically being of copper and each one about oneeighth of an inch. The purpose of this loose cable is to afford a greater area of heatingsurface, so that the hydrocarbon entering the coil will be divided up and brought into intimate contact with the strands of the cable, thus obtaining a quicker and more complete vaporization of the oil.
Having described my invention and set forth its merits, what I claim is 1. In a furnace, the combination of an oilvaporizer located at the fire-box to be heated and have the oil vaporized by heat from the furnace fire-box and havingavapor-pipeleading therefrom to a point outside of the furnace, means for conveying heated air from a part of the furnace and mixing the oil-vapor therewith outside of the furnace, and means for drawing the air and vapor to the mixingpoint and impelling the mixture of oil-vapor and heated air into the fire-box, substantially as described.
2. In a furnace, the combination of an oilvaporizer located at the fire-box to be heated and have the oil vaporized by heat from the furnace fire-box and havinga vapor-pipe leading therefrom to a point outside of the furnace, means for conveying heated air from a part of the furnace and mixing the oil-vapor therewith outside of the furnace, and means for drawing the air and vapor to the mixingpoint and conducting the mixture of oil-vapor and heated air from the mixing-point through separate channels and delivering it into the fire-box from opposite points in its walls, sub stantially as described.
3. In a furnace, the combination of an oil- 'vaporizer located at the fire-box to be heated and have the oil vaporized by heat from the furnace fire-box and having a vapor-pipe leading therefrom to a point outside of the furnace, an air-heater in the smoke-stack, a pipe for the heated air leading from the heater in the stack, said pipe and oil-vapor pipe delivering into a chamber outside of the furnace wherein the heated air and oil vapor are mixed, and means for drawing the heated air and vapor to the mixing-chamber and impelling the mixture of oil-vapor and heated air from said mixing-chamber into the fire-box,
'ing therefrom to a point outside of the furnace, a pipe for conducting heated air from the smoke-stack, said pipe and oil-vapor pipe being in communication with a chamber outside of the furnace wherein the oil-vapor and heated air are mixed, and a fan for drawing air through said air-pipe from the stack and impelling the mixture of oil-vapor and heated air into the fire-box, substantially as described.
