To all whom it may concern:
Be it known that I7 REINHOLD SCHNEIDER, a citizen of the United States, and resident of Sharon. in the county of Mercer and State. of Pennsylvania, have invented a new and useful Hvdrocarbon-Burner, of which the following is a specification.
My invention relates to the construction of hydrocarbon burners, and more particularly relates to burners for tar and similar liquid fuels constructed and arr-anged for use in connection with inetallurgical furnaces.
One. object of the invention is to provide a liquid fuel burner adapted for use in burning ta-r and similar hydrocarbons having; novel nieans whereby coking of the tar on the interior of the appar'atus is avoided and overcome.
Another object of iny invention is to provide a -liquid fuel burner having novel means whereby the discharge end or nose of the burner is effectively prevented from becoining overheated and is protected against burning.
A further object of this inrention is to provide a liquid fuel burner having novel the burner is cooled and by which Cooling of the liquid fuel in the burner is prevented.
still further object of the invention is to provide a burner having novel means whereby the quantity of fuel passing through the apparatus is regulated and controlled and by which the fuel conduit is cleaned and cloggilrer of the fuel conduit'is prevented, without necessarily reinoving` the apparatus from the furnace.
still further object of this invention is to provide novel means whereby the burner is inovably Secured in operative position, and is adjusted and held in lengthwise and angularly adjusted position.
Still further objects of n'iy invention will be disclosed hereinafter as the invention is lnore fully describedand claiin'ed.
Referring to the drawinfzs, forining part of this invention, Figure 1 is a sectional side elevation of a regenerative open hearth furnace showing a hydrocarbon or liquid fuel burner constructed and arranged and applied for use there-on in accordance with my invention. Fig. 2 is alongitudinal section. on a larger scale` showing; in detail one forln of hydrocarbon burner as constructed and arrangedin accordance with this invention. Fig. 3 is a sectional end elevation of the burner shown in Fig. 2, the section being taken on the line IH-HI of Fig. 2. Fig. is a sectional end'elevat1on of the same on the line IV-IV of Fig. 2.
In the accoinpanying` drawings, the numeral 9 designates a pipe fo-rining a conduit for the tar or other liquid fuel, terminating at the discharge end of the burner in a nose having an outwardly tapering nozzle 3 which is adapted to be engaged by the tapering end 1 of the rod forniing the needle valve 5 by which the size of the Opening in the burner end of the conduit :2 is varied in regulating the supply of liouid fuel passin;r through the burner into the furnace or other point of use.
The conduit 2 has a series of projections 6 which are spaced at intervals on the inner surface of the conduit 2 adjacent to the nose end thereof to center and niaintain the longitudinally movable rod forming the needle valve 5 in axially central position therein.
The rear end of the pipe or fuel conduit 2 extends through registering openings in opposite sides of the hollow cast-ing forining the oasinpr 7. the rear end of the -pipe 2 being screw threaded into one end of the valve bodv 8. The valve body 8 is screW threaded by one end into the internally threaded "opening 9 in one side of the casing' 7, and a side outlet 10 is provided on the valve bodv. havino' a hose connection 11 thereon, which is connected bv its other end to a source of liquid fuel supply.,
The. rear end of the rod forrning the needle valve 5 is provided With a screw threaded portion 12 which extends through the internally threaded portion 13 of the valve body 8. and the enlarged end of the valve rod 5 beyond the screw threaded portion 12 thereof extends through a stuffing box 14 and gland 15 on the valve body and is provided with a handwheel 16 on the end thereof by which the valve rod 5 is moved to adjust the` tapering end 4 of the valve rod 5 within the nozzle 8 on the nose end of the conduit v2 and, when necessary, to shut ofl' the supply of tar or other fuel. The pipe 2 forming the liquid fuel conduit is telescoped within the larger hollow passage 17 one end of the tube forniing this surrounding passage 17 being screw threaded into the internally tlneaded Opening 18 in one side of the casing 7. The tube 17 has an integrally formed outer wall 19 of larger diameter which in turn surrounds the wall of the tube 17 for a portion vof the length of this tube' so as to form a hollow water jaoket for the air conduit 17. A ring. 43 is welded or brazfed on the tu'be 17, this ring being seated on the header 21 by screwing the outer wall or shell into the header 21. The rear end of the ^she11 or wall 19 is screw threaded into the Opening 20 in the front end of the`header 21 andthe header 21 also has a partition-therein which has an internally threaded opening 22 into which one end of the pipe 23 is screw threaded.
The pipe 23 projects` for'wardly. between the inner and outer Walls of the jacket 19 so as to form a diaphragm or partition separating the jacket 19 into two concentric water spaces for a purpose described hereinafter. Screw threaded into the rear end of the header 21 is the male member 24 of a union 25 by which the water supply pipe 26 is secured to the jacket 19 soV as to be readily detachable. A similarly formed union 27 has a male member 28 screw threaded into an'opening in the header 21 to detachably connect the water overfiow pipe 29 to the jacket. The casing 7 is provided with a screw threaded inlet 30 to which a flexible tube or other connection 31 is Secured,
through which air is supplied under pressure to the air passage in the burner.
The nozzle end of the tube 2 terminates at the forward or nose end of the burner so as to form an annular air outlet 2a between the outer wall of the tube 2 and the inner wall of the pipe 17. The'inner surface of the pipe 17 is provided with a series of projections 32 near the outlet end of the air passage to center the outer end of the pipe '-2 within the pipe 17 and form an annular disoharge Opening at the outlet end of the burner surrounding the discharge outlet Opening in thepipe 2 forming the fuel conduit. Lugs 33 are conveniently formed on the casing 7 to provide means at the rear end of the burner for suspending and maintaining the burner invposition in the ports of the furnace.
When -the burner is used on an open hearth or similar. metallurgical furnace, the
furnace 34' is provided with o'ne or more -suitable port ,openings 35 in the ends of the furnace and the burners are suspended from a trolley 36 withtheir discharge ends projecting into the port openings. The trolley is mounted upon the track 37 formed by the4 -bent bar which is conveniently Secured to the buckstays or metal framework 38 at the The trolley 36 is provided with anti-friction rollers or track wheels 39 arranged to engage with the track 37 and hold the burner in operative position and to permit the burner while so held to be moved lengthwise, to advance the nose of the burner for the desired distance into the port Opening 35 and to retract the burner as required. The burner is secured at one end by the lugs 33 thereon to an eyebolt 40 by means of which the burner is suspended from the trolley 36 on the track 37.
It will be obvious that the arrangement of the rollers or wheels 39 on the trolley 36 so as to engage opposite Sides of the track 37 will prevent any tendency of the overhanging nose of the burner to tilt the trolley in moving the trolley on the track 37.
As it is sometimes found to be desirable or'necessary to adjust the burner angularly within the port Opening 35 so as to point the burner lengthwise at the desired angle to the horizontal, an ecc'entric or Cam 41 is provided on the lower end of the trolley 36 which engages with a rib or flange on the rear end of the burner and is provided with a handle 42 by which the cam is turned to cause the nose of the burner to move from the position shown in full lines into that shown by dotted lines in Fig. 1 or, into an intermediate position as required.
When desired, the burner is moved lengthwise by shifting the trolley 36 on the trolley track 37. so as to move the burner backwardly from the position shown until the nose thereof is entirely without the furnaee end walls where it can be readily inspected, and the'distance the burner is caused to project into lthe*port openng 35 can, in the same manner, be varied as is found dsirable.
It will, of course, be understood that two or any desired number of burners can be applied for use on each end of the furnace, as is found neoessary, a suitable number of port openings 35 being provided in such case in the ends of the furnace.
In the operation of my improved burner, when applied for use on a furnace, such as that shown, the parts are assembled as shown, the pipe or tube 11 is connected with a source of tar or other liquid Vfuel supply. The inlet Opening 30 on the casing 7 is connected by the pipe 31 with a source of air or other fluid under pressure such as dry steam, and the water inlet pipe 26 is connected with a source of water supply, and the outlet pipe 29 to an overflow outlet opening.
In some cases the water supply pipes 26 `and 29 will be connected to a water tank or trough in such manneras will cause the ywater used in Cooling the nose of the burner pressure is caused to pass into the casing 7 and through the conduit 17, passing out through the annular Opening :2a in the nose or outlet end of the burner. The inlet valve which will be provided on the pipe 11 then being opened, the tar or other liquid fuel being used, being under pressure of a'sufficient head, is caused -to flow through the pipe 11 and valve body 8 into the conduit 2, finally passing .through the central fuel opening 3 in the nose or outlet end of the burner. In the meantime, Water is caused to circulate through the pipes 26 and 28 and through the shell or jacket 19 of the burner, the diaphragm or partition 28 in the jaoket 19 causing the Water to pass from the pipe :26 to the front or nose end of the burner and then backwardly and out of the jacket through the outlet pipe 29. pbviously, the Connections can be reversed, and the Water caused to enter through the pipe 29 and pass out of the jacket through the pipe 26. i
After the fiow of air is started and the tar begins to discharge from the nose of the burner, the volume of tar passing through the annular tar outlet Opening is regulated by turning the handwheel 16 and adjusting the needle valve rod 5 projecting through the outlet end of the fuel conduit 2. The valve onfthe pipe 31 controlling the air supply is also turned to regulate the' air supply and permit the necessary quantity of air being supplied.
The tar under pressure is forced through the conduit 2 and as it emerges from the nose of the burner it is caused to intimately 'mix With the surrounding annular str'eam of air passing through the conduit 17 and is atomize'd and discharged into the ,furnace where the mixture of tar and air is burned.
The tar is not chilled by the water cooling eflect of the Water jacket 19, as the tar conduit 2 is insulated from the water cooling jacket 19 by the surrounding stratum or layer of air passing through the conduit 17 telescoped over the conduit`2, while the circulation of Water in the Water jacket maintains the burner in the necessary cooled Condition when used on metallurgical furnaces employing extreme temperatures.
The advantages of my invention will be apparent to those skilled in the art.
Modificationsin the construction and arrangement of the parts may be made without departing from. my invention as defined in the claims.
