BUBNER FOR LIQUID COMBUSTIBLES.

Application filed June 23, 1921'. Serial No. 479399.

To all whom it may conem: u

Be it known that I, CHARLES LINK, en ineer, citizen of the French Republic, residin at Paris, in the Department of the Seine, France, have invented certain new and useful Improvements in Burners for Liquid Combustibles, of which the following is a specification.

The invention'has for its subject improvewhich permit of obtaining complete combustion without smoke of liquid combustibles of any density and the inve tion relates more particularly to liquid com ustibles of the less fluid type such as mazout, naphtha, heavy oils, etc.

In its simplest form, the-burner essentially comprses a casing divided in two superposed compartments one of which receives the liquid combustible, the other being in communication with a suitable source of fluid under pressure. The two compartments which are of rectangular cross section are very shallow and lead to a` nozzle or dis- .tribution mouth-piece disposed in a horizontal plane insuch a manner as to direct into the furnace a sheet of atomzed combustible which escapes from the burner.

In the accompanying drawing:

Figure 1 is a transverse section of a burner constructed according to the-invention. A F igure 2 is an end view of the same burner, in elevation. p

F igure 3 is a plan vewof the cleaning tool of the burner. P i

Figure 4 shows the handle of the cleamng tool'shewn on Fig. 3.

Figure 5 is a cross section through the nozzle-line A-B, Fig. 1.

l`he burner, Figures 1 and 2 is mounted on two rods 16-16 fixed to the ironi: wall of a furnace. These rods pass. through two brackets 17-17 cast integrally with the bottom part 18 of the burner; the two rods act as slides on which the burner can be moved back when cleaning is necessary. The con nections of the burner with the mains is made by flexible pi es and proper kuce joints. If desired, te two rods could be made of tubing, through which the air necessary to thecombustion could pass.

On the furnace wall are' provided two grooves 19--19 also, in` which can be slid a plate, in order to close the opemng n the ments in burners for liquid combustibles wall and protect it, when the burner is set back; cold air is then prevented from entern the furnace and in uring its parts.

V he front wall is provided with a kind of cup 20 also cast integrally with it, and in ths petroleum is poured for starting the burner.

The compartments of the burner comprise, atop (part 21, a bottom art 1 8, and an interme ate plate 22 on w ich falls the liquid combustiblecoming from the tubing 23.

Towards its end the plate 22 is provided 'with a transverse groove 24 in which the liquid fuel pouredon .it flows, distributing itself ually across the width of the plate efore owing over the extreme end which has the shape ofa weir. 4

The groove 24: can be placed if required ust underneath the tubin or opening 23, it would act there as a kin of reservoir.

A somewhat large opening is provided on the top part 21 of the burner, it is closed by a cover or cap 26 which is lifted for inspecton or cleaning; said cap is itself provded with a smaller opening ,which can be closed by a cover 27 linked to a chain. When the burner is acting, cover 27. is removed and part of the air required for combustion pasesjthrough the opening, as shewn by the arrow, said air flowng from above to the point where the liquid fuel is pulverized. i The top part of the nozzle as well as the tongue of plate 22 are corrugated as shewn Fgure 5; these ridges produce undulations in the jet, increasing .the surface of contact between the combustible liquid and the hot air supplied to the furnace, and so contributing to the total combustion.

In the bottom part 18 are provided two openmgs 28-29 to be connected, 28 with the pipe through .which flows the fluid re-' qured for the pulverization, and 29 with a The`vertical extent, as well as 'the width, of the passage 30 for the pulverizing fluid is regulated by a cylindrical piece 31 on the circumference ofwhich two flat parts 32- 32 have been cut, one narrower than the other. Regulation is obtained by turning round said piece 31 of the required amount. When in its right place piece 31 is fixedwith a set screw not shewn.

The cleaning of the opening 30 is made with a scraper 33, F igures 1 and 3, fixed on a handle 34 on the remote end of which is a screw 35. ll`his handle can slide in a sleeve 36 screwed in the bottom of the burner aid sleeve, when the burner is working, being closed by a plug 37, which plug can be' screwed on the sleeve and on the screw 35 4 of the handle 34:; the bottom part of the burner is on account of this, proof against leakage, and besides the scraper is Secured in the sleeve.

For cleaning the plug 37 is removed and -one screws the handle 38 through'39 to the screw 35 of the scraper 33. A reciprocatory motion is then imparted to the cleaningtool,

nel in which fiows the liquid. In this 'case it will be necessary of course 'to disconnect' the piping which then must be provided with proper quick setting joints. If the cover is 'made to oscillate horizontally 'on a pivot, the changes-in shape of the piping may be small and disconnection avoided. If there is no pressure inside, the cover, of course, may be simply put on; in this case closed connection between the burner and 'the feeding piping is unnecessary, and the ,liquid fuel may then descend through an opening on which a funnel could be placed.

When the burners are divided in several parts which can be either connected or .dis connected through an automatic regulator of feed, it is necessary to have as many separate pipes or funnels that there are separate burners, but in order to prevent the tendency of the liquid fuel, in this case, to

distribute itself all over, it is' good to provide some kindpf guide plates from which the liquid falls in drops.

l. In a bumerfor' liquiduel the combination of upper and lower chambers separated by amedially arranged fuel' carrying plate, opposite openings formed'in the walls of said chambers and extending along the margin of said. separa'ting plate, means for maintaining a flow of-- gas under.` `ressure through one of said chambers and rom the said opening in the wall thereof, means `for maintaining a flow of flame-nourishingair through the V other chamber and from the said opening in the wall thereof, and means for maintaining a stream of fluid fuel over said plate and from the margins thereof between the openings in the chambers.

2. In a fluid fuel burner a transversely extending plate adapted to sustain a stream of fluid fuel and to allowthe fuel to escape by gravity over its edge, a nozzle wall arranged beneath and 'opposite the edge of said; plate and forming therewith a nozzle, such nozzle forming the orifice of a Conduit for compressed gas, and a movable member arranged adjacent the orifice formed by and. between the said nozzle wall and the' edge of saidplate andbyv movement 'efl ecting variation in size of such orifice.

3. In a fluid fuel burner the combination with a transversely extending plate adapted to sustain'a stream of fluid fuel and to allow the fuel to escape by gravity over`its edge, a nozzle wall arranged' beneath and opposite the edge ofsaid plateand formng' therewith a noz zle, means for causing a stream of compressed gas to' flow through said nozzle, and a'scraper borne by the :structure and adapted to be advanced through said nozzle and retracted again to inactive position;

'llntestimony whereof I afiix' my signature. a
