runnsraav mrrusnn'.
To all 'whom it may concern( t. it known' that we, MICHAEL PAPA- ,Fnnonorrg mechanic, and VLADIMIR Scon- -crumn'rrn `gngineeig-fboth of 6 Rotte No. 15,
St. Petersburg, Russia, have inventeda certain new and useful Improved Fuel-Spnay Diffuser, of which the following is a sp'ecii'ication.
rhis invention relates to a device for spraying liquid fuel into the furnace of steam boilers andthe like. Spray diusers have already been proposed 1n which the fuel is diiusedby means of compressed air or by Steam, or' in other devices the. fuel is conveyed by the pressure of air or-steam and the diffusion isfobtained by directing the fucl-jetagainst a metallic tongue or by the employment 'of the so-called diera-spiral.
`These devices have, however, the disadvantage of inconipletely diffusing the fuel, producing a noise and o ur invention has the purpose of removing these'disadva-ntages by providing the diffuser Y with two nozzles which are arranged at a suitable angle with regard to each other, the arrangement being such that the two jets of fuel leaving the` nozzleare forced into'lone another. A perfeet and noiseless spraying of the fuel is thus ol'itained.
In the accompanying drawings two forms of carrying out our invention are shown.
Figure 1 is a longitudinal section, and' Fig. 2 shows a part of the diluser in side eleva# tion, While/Fig, 3 is alongitudinal section of a modified form. Fig. 4 a sectional view taken on the line A-B Fig. 3, and Fig. 5
Va plan view of the modified form.
The diiuser consists of a body 1 which by ns of a tube 2 is connected to the nozzle- Il' by means of an interp'od member 8'. A fylinder having'openings 4 is y rovided within the said tube 2, and is pressed against the member 8 by means of the threaded end portion or lid 6.
vln order to prevent leakage and t insure., a perfect fitting upon eachother of the fuel passages in the two members and 8, the` end of the tube 5 is conical and fits exactly into the conical seating arranged in the interposed member 8.
"ihm passages 9 are provided in the nozzle head 3 and their axes are arranged so as to crass each otheira short dist-ance from the nozzle end at the point These passages a re tapered so as to be'of less cross sectional .diameter at the end of `thenozzle ,andl apart from this, are extended right through the nozzle head in order to enable easy cleaning of the saine in case the passages'should-get Stoppers 11 have been removed. A wire netand serves as a filter for the-liquid fuel.
The diiuser operates in the following manner: The fuel is conveyed under pressure through the 'opening 13 in the body 1 into the annular chamber 15 and enters the interior of the tube 5 through the filter 12 and openings 4, after which it passes through the passages 16 and 9, 3, where it leaves the dozzle in the form of two colliding thin jets. A collision of such jets is perfectly noiseless. On account of the described construction of the filter, its surface is sucha large one that local interruptions of the saine by impurities does not aieot the working of the'device.
In cases Where the boiler is under exceptional stress so that it becomes necessary to introduce an additional quantity of air in order to obtain an economical combustion of the fuel, which particularly is the case if mixed fuel is used (naphtha and coal) ason battle-ships vfor inst-ance, it is advantageous to provide the. diffuser with a separate air flue into-which air under pressure is introduced. The modified form of our invention as shown in Figs. 3 to 5 is specially adapted to answer this purpose. The various parts of the dii'user are substantially similar to those shown in Figs. 1 and 2, with t-he difference. however, that the body 1' is provided with an air inlet 17 and that the tube 2 is surrounded by a cylinder 18. The interposed member 8 has a number of bores 19 which terminate `in the annular chamber 20 from which chamber the air is sucked through a passage 21 into a channel 22, arranged vertically to the passage 21.` The channel 22 communicates withv a,slot 23, which is positioned adjacent the ends of the passages 9. A
The tubes 2 and 5 are preferably not connected directly with the nozzle 3 so that if the nozzle isdamaged it may be removed and another nozzle put in its place Without taking the device apart.
Having now particularly described and ascertained the vnature of our said invention blocked up, and after the closing screws or Patented Mal. 111, 1913.
ting or sieve 12 surrounds the inner tube 5 and in what lnanneiutbe same is to be performed, we declare that what we claim is :M
1. ln a device. for spraying liquid fuel, a nozzle having two passages. the ends of which are 'inclined toward one another, a fuel tube communieating with said passages and provided with an opening?r for the introdiu'tiou of fuel, said tube being provided willi a riunovable end portion, a ronneeting member interposed between said nozzle. and said fuel tube, a perforated tube positioned within said fuel tube. and having one end en- ;agrinfgrsaid connecting member and its other end engagingr said end portion. and a filter surroundingy said perforated tube.
2. ln a device for spraying;r liquid fuel, a nozzle having two passages, the ends'of which are inclined toward one another, a,
fuel tube communicating with said passages and provided with an opening for the introduction of fuel, a connecting member interposed between said nozzle and said fuel tube, a perforated tube positioned within said fuel tube, a 'filter Surrounding said perforated tube, and an air tube surrounding said fuel tube. said air tube eon'ununicating With an ol'ieniug positioned adjacent said passages.
In testimony, that we claim the foregoingr as our invention, we have signed our names in presence of two subscribing Witnesses.
