- APPARATUS FOR BURNING HEAVY OILS.

SPECIFICATION formingpart of Letters Patent No. 739,153, dated September 15, 1903.

Application filed September 20. 1902. Serial No. 124,170. (No model.)

To all whom it may concern: Be it known that I, FRANK Go'rToN, a subject of the King of Great Britain, residing in 'the city of Sydney, in the State of New South Wales, in the Commonwealth of Australia, have invented certain new and useful Improvements in Apparatus for Burning Heavy Oils, of which the' following is a specification. My invention relates to improvements in apparatus for burning heavy oils for the production of heat; and the object of my invention is to combine aheavy residual oil with steam under pressure, so as to produce ahighly-combustible gas, together with a continuous supply of oxygen, and thus obviate the necessity for a forced draft. Devices for this purpose comprise. generally an oil-supply and means for introducing the same such as a force-pump or injector-a steamsupply, a mixing-chamber, and a vaporizingretort from which the fuel escapes in a gaseous form.

My invention consists, essentially, of the combination of a heavy residual oil with superheated steam and the subsequent vaporization of the former and decomposition of the latter, which results in the production of a highly-combustible gas and a supply of oxygen.

In the drawings I have shown a simple and efficient apparatus for applying my invention to an ordinary steam-boiler. This apparatus consists of a horizontal cylinder with closed ends, hereinafter called the mixing-chamber, the steam and oil supply pipes, and a cross-tube leading from the mixing-chamber to the vaporizing-retort.

Figure l is a front elevation of my apparatus. Fig. 2 is a plan; Fig. 3, a horizontal section. Fig. 4 is a vertical cross-section.-

ot is the mixing-chamber.

b is the supply-pipe, which passes through the mixing-chamber in the manner shown. This pipe has a longitudinal row of perforations in the bottom thereof. b b are coiled flexible extensions of this tube provided for Y the purpose of somewhat raising the temperature of the oil before introduction ,into the mixing-chamber.

c is the vaporizing-retort,which overlies the fire in the furnace.

c is the aperture through which the gaseous fuel passes into the furnace, where it is ignited.

dis the lateral tube passing through the cylinder and into the retort. The portion of this tube which is within t'he mixing-chamber is provided with perforations top and bottom, while the portion within the retort is circumferentially perforated about two-thirds of the distance,leaving the bottom clear.

3 is a loop by means of which the position of the apparatus can be altered, as hereinafter described.

The method of operating my invention is as follows: Assuming that steam has been raised in the boiler with ordinary fuel and the apparatus, as above described, placed in position, preferably on a seating secured to the dead-plate of the furnace, with the vaporizing-retort overlying the fire and having the ends of the supply pipe I) Z? projecting through the f urnace-door, these ends are respectively attached to the oil supply (with intermediate force pump or injector) and steam-supply. The controlling-valves being opened, oil and steam are simultaneously injected into the mixing-chamber through the perforations in the bottom of the tube 1) and thoroughly mixed therein. From thence they pass through the cross-tube (1 into the retort c, which, overlying the furnace, is subjected to sufficient external heat to cause the vap orization of the oil, the carbon of which uniting with the hydrogen of the steam forms a highly-combustible gas, which, together with the oxygen set free from the steam ,passes into the furnace through the aperture 0 and being ignited produces an intense heat.

Roughly speaking, the oil will occupy the lower half of the space within the mixingchamber and the steam the upper half, and as the lateral tube dis medially placed within the said cylinder similar proportions of oil and steam will be forced into it and will be expelled from the perforations therein which are within the retort.

The gas from the retort may be projected into any part of the furnace by altering the set of the apparatus. The loop 6 is provided to facilitate this movement. Of course there are many other methods by which myinvention can be carried out, as any simple means of mixing oils of the class specified with steam the cylinder, a retort on the cylinder and having an aperture, and a perforated pipe providing communication between the chamber and retort.
