Speciflcation 'of Letters Patent.
Pdtented Sept. 20. 1921.
T all whom z't may ccmce%n Be it known that I,EDWARD H. SCHWAR'IZ,
- a citizen of the United States, residing at.
Chicago, in the county of Cook and State of Il1inois, have invented a new gmd useful Impr0vement in Burners, of wh1ch the following is a specification.
This invention relates to fuel burners and central open1ng m the cap 32 und extends is fully desc1ibed in the foll owing spec ification and shown in the accompanymg drawing in which Figure 1 1s a s1de elevation showing the furnace to which it is applied in section;
Fig. 2 is an[ end eleVation of same;
Fig. 3 is an enlarged vertical section through the burner Fig. 4 is a horizontal section on the11ne 4 0f Fig.3;
Fig. 5 is an enlarged end view of the asp1- rating nozzle of Fig. 3; and,
Fig. 6 is an enlarged partial longitudmal section on the line 6 of Fig. 3.
The embodiment as illustratdd is shown as applied to a furnace having a wa1l 10 t0 which is bolted a fiange 11 in which is secured a hollow casting 12. A hollow member 13 is screwed into the c asting 12 und has a partition 14 extendin diagonally acro ss the interior as shown in igfi4. Pipes 15 and, 16 connect with ea'ch other through a coi1 17 in the brickwork of the furnacg all and serve to com1ect the chambers formed on the two sides of the partit iori 14. A hollow fitting 18 is ecured t0 the mem-' ber 13 andhas a. hollow casting 19 secqred thereto, preferably with its axis at r 1ght angles to the members 12, 13 aamd 18. A
taper ed nozzle member20 extends into the casting 19 and' has a hollow fitting 21 se-- bured at its outer end, the latter being clos'ed by a cap 22. A tube 23 extends longitudinally of the members 19 und 21 and is' screwed at one end into the cap 22 and is held at the other in the nozzle member 20.
This tube ope.ns f r0m the atmosphere into the mixi11g chamber 25 within the casting 19.
A hollow assage 26 surrounds the taube 23 and has a se1ies of longitudinal orifices 27 opening into the mixing chamber 25, as
shown in Figs. 3 and 5. The passage 26 is connected to any suitable source of steam or air supplv by a pipe 28 and the pressure i's co1'1trolled by the valve 29.
Air is introduced into the large chamber 30 in the cas ting19 through 011e or more.
centrally through the members 12, 13 a1id 18, the partition 14 in the membep 13 having a central op6ning 34 which is cloSed by the fue1 nozzle 33 und acts as a support therefor.
Referring now to Fig. 6 the discharge end of the fuel nozzle 33 is closed by. a plug 35 which has a central opening 36. This opening is controlled by means of a needle valve 37 having a stem 38 which is operable by nieans of the band wheel 39 as shown in F ig. 3. The space 40 in front 0f the fuel nozzle is therefore a combustion chamber and this is surrounded by a hollow.jacket 41 in the casting 12 to which liquid or gaseous fuel is supplied from any suita.ble source through the pipe 42. The heated fuel then passes through the pipe 43 and thenkze through the fue1 nozzle 33. The method of operation of this' device is as follows:
When not in operation the vglves 29 and 39 are closed. The valve 29 is firstopened causing a supply of air or steam to be forced through the orifices 27 thereby inducing the flow of air to the tube 23 and the pipe 31. Thism ixture of air or air und. steam as the case may be, passes through the narrow portion 25 vand the member 18 into the pipe 15 as shown by the arrows in Fig. 4. This mixture then passes around through the coil 17 in the brickwork forming the side Wall of the furnace to which it is applied} and .if'the side Wall is hot this mixture is highly preheated and returns through the pipe 16 on the opposite side of the artition 14 a.s shown by the arrows in Fig. 4. The valve 37 is then slightly opened by means of the hand-wheel 39 and fuel frm the fuel nozzle is a plied. W?hen liqpid fuel is used, it is highly prewhich it is my intention to cover all noveltyhet6d und is sprayed into the combustion chamber 40 in the form of a gas or vapor which mixes readily with -the preheated. air und forms a. combustible m1xturd which burns readily and completely. When gaseous fuel is used, the gas 1s heated und expandedbefore mixing with the prehkated air andthe result to both caseS is that a, more eflicient combustion und a hotter, oleaner fire is obta.ined.
I f desired, th e casting 19 and parts Carried thereby may be omitted und a blower 0r other means for supplying the air ma.y be attached. to the' fitting 18.
While'1 have shown but a. single embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore,in the construction und arrangement may be ma.de which do not depart from the spirit und scope of the invention, as di'sclosed in th'e appended claims in inherent in the invention Ias broadly a.s possible in view of the prior art.
What I clai1 n as new and desire to secure by LetterskPatent is:
1. A fuel burner having an air chamber and a mixing chamber separated by a partition, means for supplying air to Said air chamber, a. hollow heatingelement surrounding said mixing ohnmber, piping leading from the air chamber to said heating element, pipin leadilig from said heatin element to sa.i mixing chamber, und a. fue nozzle adapted to spray fuel into the stream of preheated air.
2. A fuel burner domprising a hollow sentra1 portion having a. transverse partition, means for supplying air to the hollow portion at one side of said artition, a. hollow heating element, piping leading from sa.id hollow portin on o ne side of sa.id partition to said heating element and back to said hollow portion on the opposite side of said partition and a fuel nozzle adaf ted to spra.y fuel into this stream of preheated air.
3. A fuel burnei, means for supplying air t0 the burner, a. hollow heating element, piping leading from the burner to said heating element and back to said burner, a. fuel nozzle adapted to spray fuel into the stream of preheated air a combustion chamber in which said combustion takes plage, a jacket insa.id chamber in which the fuel is heated and means for (zarrying the fu'el from said jack6t 130 the fue1 nozzle.
4. A fuel burner comprising a hollow central portion havingfa. transverse Partition, means for supplying air to the hollow portion at one s1de of said artition, a. hollow heating element, piping leading from said hollow portion on one s1de of said partition to said heating element und back to said hollow portion on the opposite side of said. partition, a fuel nozzle adapted t0 spray fuel into this stream of preheated air, acombustion chamber in which said 'combus- 'tion takes place, a ja.cket in said chamber in which the fuel is heated and means for ca.rrying the fuel from said jacketto the fuel
