JOSEPH B. MOORE, OF READING, PENNSYLVANIA.
INJECTOR OIL-BURNER.
SPECIFICATION forming part of Letters Patent No. 426,040, dated April 22, 1890.
I Application iled September 6, 1889. Serial No.323,l32. (No model.)
To all whom t may concern:
Be it known that I, JOSEPH B. MOORE, a citizen of the United States, residing at Reading, in the county of Berks and State ot Pennsylvania, have invented certain new and useful Improvements iu Injector Oil-Burners; and I do declare the following to be a full, clear, and exact description ot' 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 letters of reference marked thereon, which torni a part of this specifica tion.
This invention relates to certain improvements in injector oil-burners, the object of which improvements is to secure thoroughly satisfactory adjustment of the oil supply whereby a uniform lire of any desired intelisity may be maintained without requiring the services of an attendant, and also to secure perfect combustion of fuel.
The invention is fully described hereinat ter and specified in the claims.
Figure l is a sectional view of my improved burner. Fig. 2 is a sectional view showing my burner and apparatus adapted to the firebox of a vertical boiler. Fig. 3 is a plan mainly in section through X. 'Y of Fig. f2.
The main piece E of my burner is a casting, from which branch out the several` tubes required in its construction.
The burner proper consists of an inner oiltube L, which is secured into the smaller threaded opening e of the casting and projects at right angles to the oilsupply tube F, and an outer air or steam tube K, which is screwed into the larger threaded portion e of the casting and incloses the oil-tube L throughout its length, the space between the two communicating with a steam-'pipe G and also with an air-pipe M, the purpose of which will be hereinafter explained. The oiltube L terminates in a tapering nozzle Z and the steam-tube K in a similar tapering nozzle 7c, which loosely surrounds the nozzle Z, leaving an annular steam-outlet around the point of the latter. A Valve Il, having a taper corre spending with the interior of the nozzle Z, has formed on its surface a number of shallow parallel grooves hi, and is provided with a long stem 71 which extends rearward and projects through the main piece E, being threaded at 7L', and provided with a handle h3, to permit of convenient adjustment of the valve II in the oil-nozzle. A packing-gland .I prevents leakage around the projecting stem.
In Figs. 2 and 3 I have shown my complete apparatus adapted to the iire-boxA of an ordinary vertical boiler. The grate ordinarily used is dispensed with and a cylindrical combustion-chamber O, of rolled metal, is placed centrally in the hre-box, and is open at the top. rlhe base l3,upon which the boiler rests, forms an air-chamber around the combustionchamber C, to which air is admitted at suitable points b, and from which it rises through the reduced annular air-passage b', near the top of the combustion-chamber, into the firebox. The burner already described is represented as supported in any suitable manner with the main part outside of the boiler, but with the nozzle projected through the airchamber B and the wall of the combustionlchamber O into thc latter, a funnel-shaped air-tube D surrounding it. rlhe pipe F is connected with an oiltank placed at any convenient point, andthe pipe Gwit-h the steamdome of the boiler, and both are provided with suitable valves for regulating. (Net shown.) The steam-pipe G is, however, not carried directlyto the burner from the boiler, but is first passed into the combustion-chamber, where the pipe is in direct contact with the most intense heat, thus superheating the steam before it is passed through the burner.
The operation of my apparat-us is as follows: In maintaining a tire the oil passes from the tank through the tube L of the burner, being surrounded throughout its passage by the superheated steam already re ferred to, and thereby considerably heated before reaching the nozzle l. around the spiral grooves 71,2 of the valve II, and, escaping at the point of the nozzle, is still further broken up' and vaporized by contact with the annular steannjet, which, seizing and mixing with it, carries it with great force into the midst ot the combustioirchamber, where it may be more generally scattered, if desired, by a detlector c. Air is drawn into the combustion-chamber through the tube D; but the main supply to the tire-box is through the air-ehamber l; and passageway b ,where The oil passes IOO it is brought into contact With the Wall of the combustion-chamber and is highl y heated. The combined effect of the apparatus is that the thoroughly-mixed steam and gas is consumed in the highlyeheated air supplied to the fire-box, and an intense heat is produced with a comparatively small consumption of fuel. Its intensity, however, may be very nicely regulated by means of the valve H in connection with the main steam and oil valves. Vhen the boiler is cold, I prefer to use an air-j et as a substitute for steam, and
therefore provide a connection at M to an air-- to the body-piece, the air and steam pipes discharging into the passage communicating with the surrounding steam and air tube, as described, and a longitudinally-adjustable valve located Within the oil-tube.
. 2. An oil-burner consisting of an oil-tube having a tapered nozzle, and a surrounding steam and air tube also having a tapered nozzle, a main body or casting having `passages, one of which communicates with the oil-tube and the other with the surrounding steam and air tube, oil, air, and steam supplypipes secured to the body-piece, the air and steam pipes discharging into the passage communieating with the surrounding steam and air tube, as described, and a longitudinally adjustable tapered valve located Within the oiltube and provided With parallel spiral grooves along its tapered end.
In testimony whereof I affix my signature in presence of two Witnesses.
