To form vational view showing a modified construction of a more efficient gaseous fuel and for conditionthe fuel gasifying apparatus, ing the oil gas generated in the portions 14, suit- Fig. 3 is a cross-sectional view taken on lines able amounts of a gaseous fuel constituent or 3--3 in Fig. 2; and medium, such as steam orl compressed air are 11d supplied through a pipe 32 into an annular passage 29h formed in said valve 29, said passage having openings 29o through which the steam or air is injected into the chamber 31 so that an intimate mixture of the gasifled oil and steam or air is obtained. Where compressed air is used as the medium, an installation as shown in Fig. 1 may be employed. Here the air is supplied by a suitable. compressor 33 to a supply tank 34, hence through a pipe 35 to an inlet 36a adjacent the rear end of a 4jacket 36 which surrounds the chamber compartments 17 and 18 in portion 14 as is clearly shown in Fig. 2. For controlling the flow of air through the jacket 36, a valve 37 is installed in the pipe line 35, the front or outlet 36h of the jacket being connected directly with the pipe 32 for supplying air to the valve 29.

For preheating and gasifying the fuel constituents passing through the portion 14 and chamber 36, any suitable heat source may be v provided, preferably, as here shown, an electrically operated heater 40. Said heater is constructed to t into a longitudinally extending pocket 14a in portion 14 forheating the inner jacket wall 36e and the walls 17a, 17b, and 18a, 18b of the chamber compartment 17 and 18. The jacket Wall 36e is spaced from thewall 17a and 18a to permit the extension therethrough'of a y plurality of heat resistant elements 41 of heater 40. Said elements are supported at each end by a suitable terminal member 42 which is mounted on an insulating base 43, the latter forming a closure for the pocket 14a, as is clearly shown in Figs. 2 and 3. `Suitable binding posts 44 may be provided to extend through said base for connecting said heater elements 41 in series with a suitable control rheostat` 45 across a suitable electric power source (not shown) through conductor Wires 46.

It is clear from the drawing that the heater 40 when connected to the electric power source is effective to supply the initial heat to the gasifying apparatusll for raising it to the required temperature to gasify and preheat the fuel constituents. 'Ihe heater 40 may be operated to positively control the temperatures to which the liquid and vaporized oil in compartments 17 and 18 are subjected during the gasifying and pre'- heating process simultaneously with the preheating of the air in the jacket 36 simply by adjusting the rheostat 45 to regulate the power supply.

One dominant feature of the invention resides in the provision lof the baille 19 which may be made of any ,sf 'table material having catalytic properties when heated, such as nickel, platinum, palladium, copper, brass or other like substances. As shown in Fig. 2, the baille 19 is in the form of a cylindrical tubular structure, one end thereof abutting the front wall 14h of the portion 14- and the other end thereof being supported by the rear end wall 16a of the tubular member 16. The rear end of the axial passage 19c extending through the baille communicates with the pocket 14a adjacent said wall 16a thereby providing a relatively large heating surfacel for the baille exposed to heat from the heater -40 whereby the catalytic effectivenessof said baille is greatly increased.

In Fig. 2a is shown a modified form of the invention in which a vsupplementary electric heater 140 having terminal post 144 is provided, said posts being preferably connected in series with a rheostat 145 to a suitable power source (not shown) by conductor wires 146. Said her extends through the rear end wall 14o of the portion 14 and into the axial passage 19e of the baille 19 for independently controlling the temperature and the catalyzing effect of said baille.

The normal operation of the equipment above described is as follows: Liquid fuel is fed under pressure through the valve 22 into the gasifying apparatus 11 where it is vaporized, expanded and subjected to catalytic action in the compartment 17, the gases therefrom being preheated further expanded and catalyzed in the compartment 18. The heated gasied fuel passes from the compartment 18 through the passage 15 and the valve 29 into the chamber 31 where they are intimately mixed with the heated compressed air coming through the pipe 32 from the jacket 36, prior to passing through distributing passages 39a of an elongated nozzle 39 which extends into the intake pipe 10a as shown in Fig. 2.

The equipment described above may have a tendency to operate irregularlyespecially under fluctuating load of the fuel consumer. This undesirable tendency is apparently due to the building up of a back pressure during the vaporization and expansion of the liquid fuel in compartments 17 greater than the normal pressure of the liquid fuel being fed by the pump 23. To overcome this undesirable tendency, a device R for automaticallyregulating the feeding of the liquid fuel is provided. Said device may be inserted in any convenient location in the feed pipe line 25, or as shown in Fig. 2 may be incorporated to form a part of the valve 22. Said device R is seen to include a vertically slidable member having a valve disc 61 mounted on its upper end thereof, said disc being adapted to raise against a seat 62 for shutting off the back flow of the liquid fuel due to any sudden fluctuation of load or for any other cause which is effective to increase the pressure of the gas in the compartment 17 above the feeding pressure of the liquid in the pipe 25. Normally, the disc 62 is in the position shown in Fig. 2 which permits the flow of liquid fuel around the slidable member 60 and into the body of the valve 22.

The improved process for forming a heated highly combustible gaseous fuel from a hydrocarbon oil and air is thus seen to be a result of gasifying the oil, preheating same, and while in this preheated gaseous state, combining it with the heated air under pressure without appreciably lowering the temperature of the mixture and further subjecting the oil during the gasifying process to a catalytic action which is effective to eliminate deposits of carbon residues in the compartmentsY 17 and 18. This process is easily and simply carried out by controlling the heating of the gasifying apparatus 11 and the valves 22,

29 and 37. The radiation heat losses may be greatly diminishedl by making the pipe 32 as short as possible and providing suitable heat insulating laggings or coverings 65, 66, and 67 over the exterior surface of the apparatus 11, pipe 32 and intake 10a, respectively. In Fig. 4 is shown an apparatus applied to a furnace wall W. Here, the nozzle 39 is replaced by a burner/ nozzle 139, the latter being mounted in position in any suitable manner by a frame 70, orices 70a. being provided in said frame 70 for admitting air from the outside. The air passing through said orifice may be regulated in any suitable manner for supplying any excess air that may be needed during the operation of the burner, as by means of aring or sleeve 71 having opening 71a which ring may be operated to close the orices 70a.

It will be noted that the hydrocarbon oil is merely vaporized and expanded but is not cracked or broken down, due to the temperature control preventing such reaction, the gasied oil being furthermore intimately mixed with the gaseous fuel constituent without application of additional heating, thus preventing reaction with the gaseous constituent.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:-

l. The art of preparing a gaseous highlycombustible fuel from liquid and gaseous fuel conthereto, preheating the gaseous constituent by applying a different source of heat, regulating the intensities of both sources of heat for controlling the gasification, catalytic activity, and the preheating of the gaseous constituent to bring said constituents to a desired condition, and injecting the preheated -constituent into the gasied constituent in proper proportion to form a gaseous, highly combustible product.
