Application led October V31, 191;?. Serial No. 199,504.
T0 all whom it may concern ,Be it known that we, WAILBUR H. GEES- MAN :and ARTHUR G. MCKEE, citizens of the United States, residents, respectively, yof Youngstown, county ofMahoning, and State of Ohio, and Cleveland, countyof Cuyahoga,
andzState of Ohio, have invented new and useful Improvements in Methods of and Means for Burning Air and Gas, of which the following is a specification, the principle of theinvention being herein explained and the best mode in which 'we have contemplatedapplying that principle, so as to distinguish it from other inventions.
Our-invention relates to methodsof a'ndk means for yburning air and gas. Said iinvention is particularly applicable for use 1n connection with blast. furnace operations or,
other operations where lea-n gasesof a low B. T. U. are utilized. Y Y
The object of the invention is to procure conveniently and'economically a well mixed fuel, a 'short {iame and very hotcombustion.
The annexed drawings andthe following' description set forth in detail certain steps andcertain means embodying our invention, the disclosed steps and means, however, constituting but one of various methods and vmechanical forms in which the principle of the'invention may be employed.
In said annexed drawings:
Figure 1 represents a central vertical longitudinal section V ofa gas burner embodying our improved means and an exemplification of one way of carrying outthe steps ofl our improved method, a suggestion of the ordinary blast. furnace stove and foundation therefor being also shown; Fig. 2 represents` a transverse verticalv section, taken in the plane indicated by the lines II-II, Fig. 1, thestove door being shown in its open position and the mixing apparatus in operative position relatively to said stove; Fig. 3 represents a side elevation, partially in section, of certain elements of our improved means;
, Fig. 4 represents a side elevation of certain elements of our improved means, showing the same removed from operative relation to the stove and showing a suggestion of the usual means for longitudinally moving the gas burner; Fig. 5 represents a central vertical longitudinalfsection through the stove door when the cover is closed thereover; and Fig. 6 represents an end elevation V- ofthe combination shown in Fig. 5 and taken from theright hand side of Fig. 2. f1
In the annexed drawings an exemplification of our improved burning means is shown in relation vto a` blast furnace, the usualstove of which is indicated by the ordinall', the stove foundation being indicated ,by-1 and an annular casing by 12 which surrounds and lies adjacentL to the -stove dooropening to `which is fitted the usual cover as hereinafter explained. There is provided adamper controlled' gas conduit 2 leading to the annular comparativelythin nozzle 3 surround-r` ing the air nozzle 4,"which is also damper controlled, as shown. Saidnozzles 3`and 4i are designed to furnish gas and air tothe combustion` chamber 5 ofthe`stove1. There is furnished to the chamber an additional supply of air through an annular opening L6 surrounding the nozzle 3. desiredto discontinue thefurnishingof the gas and air tothe stove 1, the nozzles 3 and Whenever it is 4 are moved back away from the door of the stove 1 in the manner hereinafter described and the cover 7, carried by a hanger 8 'in turn carried by suitable trolley wheels and also supporting the spider 9 of the design plainly shown in Fig.'2, adapted to inclose the bolts 10 and to `receive thehinged bolt 11, is swung l into place. The means for moving the nozzles 3.and 4 relatively to the stoveareprovided by the handV wheel`12 rotatably. se-
cured to a shaft 13 to which shaft is secured a kpinion 14 adapted to .engage with1 a rack j 15 suitably supported. Allof the aforementioned elements and their operation are well known, with the exception ofthe features controlling the relative amounts of gas andain To these wellknown elements we` have applied our improved mixing means and new method of burning which will now be described.
Y Secured to the outer surface of the air nozzle 4 by `means of bolts 16 are augershaped baffling blades 16 lforming a multiple thread helical screw, and slidably secured.
transverse, and, in the embodiment of our invention herein shown, substantially opposite to the inclination of the blades 16.
The relative amount of air furnished to the chamber 5 between the blades 17 can be regulated by adjusting the angle 18 upon the gas nozzle 3 so as to more or less close the annular opening 6. y
By the means previously described, the gas passing through the conduit 3 is given a rotary or whirling motion and passes into the chamber 5 in a helical or augershaped path, the air entering the chamber between the blades 17 being given a rotary or whirling motion in a direction substantially opposite to the path of travel of said gas. Violent eddy currents are thu's 4produced* `between the gas and air, resulting in an immediate and intimate intermixture. Further air, if necessary, in controlled amounts is furnished to the chamber 5 by the nozzle l in the general direction of travel of the gas in the conduit 3, which direction, of course, is longitudinally of the nozzle 3. Our construction produces an' annular ring of gas comparatively thin,
from three to 'four inches, surrounded byk air on both sides which of itself gives a better result than ordinarily secured. The Whirl in opposite directions given to the annular ring of'gas and the surrounding annular layer of air very greatly enhances'the speed and intimacy of the intermixture and results in an extremely short flame andy combustion of great intensity.
What we claim is:
1. In means for burning air and gas, the combination of a stove; a gas nozzle adapted to discharge into the same; an air inlet to said stove surrounding the discharge end of said nozzle; means for imparting a whirling motion to the air; and means for imparting an opposite whirling motion to the gas, both of said whirling means terminating substantially in the plane at which the air and gas enter the stove. c
2. In means for burning gas and air, the combination of a stove; a gas nozzle adapted to discharge into the same; an air inlet to said stove surrounding the discharge end of said nozzle; augenshaped baffling blades disposed in said nozzle and arranged so as to project the gas into the stove with a whirling motion; inclined blades 'intersecting said air inlet; a duct provided inte-Y riorly of the gas nozzle and arranged with its discharge and in substantially the same Y plane as the discharge end of said nozzle; and means for controlling said duct.
3. In means for burning gas and air,the combination of a stove; a gas nozzle adapted to discharge into the same; an air inlet to said stove surrounding the discharge end of said nozzle; auger-shaped ballling blades disposed in said nozzle and arranged so as to project thel gas into the stove with a whirling motion; inclined blades intersecting said air inlet; a duct provided interiorly of the gas nozzle and arranged to discharge longitudinally of the latter and with its discharge end in substantially the same plane as the discharge end of said nozzle; andV means for controlling said duct. 4
4. In an improved method for burning air and gas, the steps which consist, in imparting* to-gas and air whirling motions in opposite directions; and then discharging them into a combustion chamber from substantially the same transverse plane, whereby violent eddy currents are produced between the gas and air.
5. In an improved method for burning air and gas, the stepsl which consist,fin providing` a comparatively thin annular ring of gas; imparting thereto a whirling motion and discharging it into a combustion chamber; furnishing said chamber air interiorly of said gas ring, introducing into said cham-- ber kan annular layer of air exteriorly of said gas ring, said layer-of air having imparted thereto before entering said chamber awhirl-'` ing motion in a direction Y opposite to the whirl of said gas.
