Specification of Letters Patent.
Patented Apr. 17; 1917.
Application led October 21, 1916. e Serial No. 1127-5005.
.Toilet2 in the county of Will and State of. 5 Illinols, have invented certain new and useful Improvements'in Tar-Burners, of which the following is aspecification.
My invention relates to apparatus for and a method of burning tar and has particular reference to novel constructions hereinaf- A ter more fully described.
While tar contains a relatively large number of heat units and has a high caloriic value, its use as a fuel is not general because of the' diliiculties encountered in eli'ecting complete combustion thereof. It has been found necessary to preliminarily heat the liquid to a high degree and then to atomize the same into'a highly heated zone. This has, to a large extent prevented the utilization o f tar as la fuel for heating commercial boilers. When such attempt has beenmade, it has been common to inject the tar in a more or less atomized condition, into a firebox, upon the grate of which a bed of fuel is maintained. This is inconvenient, unecenomical in loperation for the reason that the tar is noti always burned to best advantage and rc uires constant attention.
An o 'ect in the present construction is to provi e a burner so arranged as to act as a combustion unit, -the mechanism shown acting to completely consume the tar which is employed as' a fuel. The 4arrangement 1s ssuch that a combustible gas, such as coke v'ovenor natural gas, may be employed, first as a preheating agent and later as a continuously operating adjunct to the vaporizing and consuming of `the' injected tar.
`The inventionwill be more readily understood by reference to the accompanyingv drawings, wherein- Y Figure 1 is alongitudinal sectlo'nal vlew through aburner constructedin accordance with my invention; Fig. 2 is a sectional view on the line 2(-2 of Fig. 1;
Fig. 3-is an enlarged fragmentary elevation of the tar spray nozzle, and
60 Fig. 4 is anend view of said nozzle.
The gas burner to which my novel 'tar l burner 1s a plied may comprise a cylindrical shell which form shown, the cylinder is composed of two parts 11, 12, joined by cap bo ts vide an injector 30.
- tor is ofpeculia r construction, as best shown forms a chamber 10. In theY 13. The
outer end of tho cylinder 11 is slightly con-` tracted, as at 1 4, in order to control and define the flamrl as it issues from the mix ing chamber 10 The extent of contraction will be determined by the size and shape of the ame desired. Surrounding the cylinder 11 and spaced away from the same is a similarly shaped shell 15. The extremities 'of the shell are not connected to the cylinder,
the same acting as a heating jacket forair which is drawn in by the injective force of the llame issuing from the nozzle.
The portion 12 of the cylinder is surrounded by clos ed chambers A16, lif, the former of which i: vconnected to a gas pipe 18 and the latter lo a steam pipe 19. .A plurality of spacer' radial apertures' 20 inthe cylinder 12 con nect the chamber 16 to the mixing chambel` 10.V A plurality of minute jet openings 21 connect the chamber' 174 to the mixing chainber 10. The jet o enings 21 are incliner', both longitudinally and transversely of the axis of the mixing chamber 10. The purpose of the transverse or radial inclination is to enforce a whirling moi-` tion of the gases vand a consequent more intimate mixture tl ereof. This is the sole purpose of utilizing; the steam which is admitn ted through the pipe 19; that is, to enforce a whirling moti m. This result might be secured by the use ofcompressed air 1f desired.

-. The endwall 2?. of the mixing chamber is Vadvanta e', I p: refer to associate therewith Vthe tar urning apparatus which is illus; trated. Y
The tar'burning element comprises a long tube 24 inserted mithe axial opening in the end wall 22 and held by a bracket25 se.
cured to the gas burner by -cap bolts 26. At a point near the entrance end of the tube 24 a T 27 is located, providing' aqsteam inlet 28 and a tar'in et 29. Withm the T I pro- The outer end or nozzle of the tar-injcc 105 in Figs. 3 and et. The tube is flattened to forma nozzle sla dl somewhat like a ducks bill, theexit o1 'i ce 31 of which is in the form of a narrow slot. A nozzle of this kind may be made with an exceedingly small 11 opening with less probability of becoming clogged or closed than a .plurality of small apertures having the Same area. It will be noted that the nozzle 32 for the tar is located exteriorly of the gas burner, the conduit for the, tar, however, traversing the entire length of the mixing chamber. Therefore, the tar prior to being ejected from the lnezzle 32 is highly heated, and upon being ejected instantly'vaporizes, due to the-in-[jf herent heat thereof and the heat of. the.}
mission ports being longitudinally and'transflame Within which-it is atornized.
-In an installation adapted forboilers, a, burner such as shown is located in the-fire,4 box in a suitable manner, theV gratebars L- g being previously covered with fire brick laid fairly closely together so that a certain amount of vair can be drawn in between them. In addition a Wallof checkerwork is preferably built up at the end of the combustion chamber of theffurnace in order to p 'revent the lflame from striking the boiler tubes. In order to begin operations, the gasis turned onand burned alone until a certain'heat is obtained in the combustion chamber. A small amountofl .tar is then admitted, together with steam to atomize the saine, the
` amount-of tar being increased asthe temaof .somewhat, as the heat of combustion of the perature increases. Preferably the amount of gas employed will thereafter be reduced tar will be suiiicient. The tar employed is -has been effected.
outside of as desem preferably preheated .in a separate tank in order to make it more Huid `and-nfore'easily atomized by the steam.
The arrangement is such that the atomized tar is not injected into the combustion space until it has been highly heated, the tar being atomized and injected into a s pace in whic there vis an excess of air. It isfor this reason that the tar is not released until it is entirely outside of the gas burner. The whirling flame causes a vortex and the flat 'sheet of atomized tar is drawn into the vortex` of heat and not released until combustion Both the method and apparatus may be varied somewhat and such modifications as Twill suggest themselves to those skilled in o f my invention.' Ifclaim` the art are considered'to be within the spirit ofburning tar, which con .The method a readily combustible gas with .air within a relatively confined space,
