GAS-BURNER FOR FURNACES.
Specification of Letters Patent.
Patented Nov. 5, 1918.
Application filed March 25, 1918. Serial No. 224,567.
To all whom it may concern:
Be it known that I, JOHN. Fnnnnrox SCHULHOFF, a citizen of. the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements 1n Gas-Burners for Furnaces, of which the fol lowing is a specification.
My invention relates to heating apparatus and more particularly to the application of a gas burner, tothe heating chamber of the usual hot water, steam or hot air heating apparatus, as commonly used in dwellings. The invention pertains especially to the admission and control of the air supply to the gas burner.
The object of the invention is to simplify the structure as well as the means and mode of operation of such devices whereby they will not only be cheapened in construction but automatic in action and unlikely to get out of repair.
A further object of the invention is to afford a means for intermixing the air and gas at a point in close proximity to the point of consumption without inducing'ex .cessive air currents and eddies. within the fire chamber. The purpose of the invention is to increase the efficiency of the gaseous fuel and eliminate undue losses of the prod- With the above primary and other incidental objects in view which will more fully appear in the specifications the invention consists of features of construction, the
of operation or their equivalents as hereinafter described and set forth in the claims.
In the drawings Figure 1, is a side elevation of a steam or hot water apparatus, partly broken away to disclose the appl1cationof the fuel burner construction forming the subject matter hereof. Fig. 2, is an end elevation of the burner and air control apparatus removed from the heater. Fig. 3,
is a detail perspective view of the apparatus removed from the heater. Fig. 4;, is an end elevation similar to Fig. 2, disclosing a modification of the construction illustrated in the preceding figure.
Fig. 5, is a detail perspective View.
Like parts are indicated .by similar charactors of reference throughout the several views.
While in the drawing the construction forming the subject matter hereof, has been ing, either existing or provided especially for this apparatus, as the entrance opening for the air conduit. The construction here in described is therefore not limited to the particular type and style of heater here shown'but may be applied to other types and forms of heating apparatus including the usual circular hot air furnace.
. Referring to the drawings 1, is the heater of which 2,"is the firing chamber and 3, the ash pit,separated from the firing chamber by the grate bars 4. The face of the furnace is shown provided with the usual firing door 5, leading to the firing'chamber, 2, the ash pit door 6, leading to the ash pit 3, and intermediate these doors a clinker door 7 substantially on level with the upper face of the grate bars 4. i
It has been the practice in equipping such heating apparatus with a gaseous fuel burner to locate the mixer entirely outside the heating apparatus and connect the mixer with the burner by an extended conduit through which the mixture of air and gas is conducted to the burner or po nt of consumpt on. Experience has demonstrated howwhen the air and gas areintermixed ata point in close proximity to the point ofconsumption. The desired result is accomplished in the present instance by conducting the air into the furnace or heater and mixing it with the fuel gas through a mixer located in juxtaposition to the point of consumption. A further difliculty with the usual inapparatus below the burner and all air necessary for proper combustion of the gases is carried direct to the point of consumption and controlled by a suitable air conduit ever, that the best results are attained only thereby preventing the diffusion of the air aimlessly throughout the heating chamber.
There have been shown in the drawings two burners 8, of tubular form the upper surfaces of which are provided with a multitude of small perforations for the escape of the fuel mixture. These burners are of ordinary type as now commonly employed in heating apparatus particularly gas grates or wall heaters. This form of burner has been used for purpose of illustration only. Other types of burners may be employed and the invention is not limited to this particular style. In the present instance each burner is provided with a mixer 9, connected directly to the burner at a medial point. The mixer 9, is located quite close to the burner 8, and is inclosed in the upturned portion 10, of an L shape housing or conduit 11, preferably formed of sheet metal. As illustrated in the drawing the open end of the lateral arm of the housing or conduit 11, registers with the clinker door opening 7. It will be understood that this conduit or housing may be led to the exterior of the heater through any other suitable orifice. For convenience the gas supplying pipes 12 are led through the conduit 11, and upturned end 10 to the mixers 9. If found more convenient the supply pipe 12, might be carried through the wall of the conduits 10 and 11, to any other convenient inlet point to the heater. By this construction the air supply to the burner 8, is conducted into the furnace or heater to a point quite close to the burner before being intermixed with the gas. The intermixture of air and gas thus occur's almost immediately before consumption. The mixture thus does not have the opportunity nor tendency to separate as is the case when the intermixed air or gas is conducted through an extended passage from the exterior of the heater to the burner located within. The construction described has the further function of warming the air supply during its passage through the conduits 11 and 10, prior to its intermixture with the gases. This likewise facilitates the combustion.
In order to control and to a large degree prevent the circulation of air drafts and currents within the heater by which the heated products of combustion are carried away through the flue before giving up their heat units a baffle or diaphragm 13, preferably though not necessarily of sheet asbestos is provided in a plane substantially level with the burners 8. In the drawings the baffle or diaphragm has been shown provided with slots in which the burners are positioned. This baliie or diaphragm may be supported in any suitable manner either upon the burners 8, or housing 10, or it may be supported from the walls of the heater or furnace. To deflect the heat generated by the burners 8, outward toward the walls of the firing chamber 2, the medial portion of the diaphragm or baffle 13, is preferably formed with a central corrugation or ridge '14, extending parallel with and between the burners 8. The sides of this elevated defiector are preferably covered with fiber asbestos.
/Vhile elongated tubular burners have been shown in the drawings it will be understood that the circular or mushroom burner may be used in lieu thereof.
In Fig. 4, there has been shown a modification of the construction heretofore described in which a third burner 15, is located intermediate the burners 8, and somewhat above the level'thereof, at the crown of the ridge or elevation 14. The construction is the same as that previously described except that the upturned housing or conduit 10, is formed with an extension 16, which 'incloses the mixer of the intermediate burner 15.
From the above description it will be apparent that there is thus provided a device of the character described, possessing the particular features of advantage before enumerated as desirable but which obviously is susceptible of modification in its form, proportion, detail construction or arrangement of parts, without departing from the principle involved or sacrificing any of its advantages.
While in order to comply with the statute, the invention has been described in language more or less specific as to certain structural features, it is to be understood that the invention is not limited to any specific details, but that the means and construction herein described comprise but one mode of putting the invention into effect, and the invention is therefore claimed broadly in any. of its possible forms or modifications within the scope of the appended claims.
Having thus described my invention I claim:
1. In a heating apparatus, the combination with a combustion chamber and a gas burner located therein, of a mixer also located in juxtaposition to the burner, a gas supply conduit leading from the exterior of the combustion chamber to the mixer, and an air supply conduit independent of the burner also'leading from the exterior of the combustion chamber to the mixer, whereby the air and gas will be separately conducted from the exterior of the heating apparatus to the mixer and will be mixed in close proximity to the point of consumption.
2. In a heating apparatus the combination with a combustion chamber and a gas burner located therein, of a mixer connected closely to the burner within the heating apparatus, a gas supply conduit leading to the mixer, and an air compartment independent of the combustion chamber into which the mixer extends said air compartment being open to atmosphere.
3. In a heating apparatus the combination with a combustion chamber and a gas burner located therein, of a mixer located within the heating apparatus in close proximity to the burner and an air supply conduit inclosing the mixer said air conduit being open to atmosphere.
4. In a heating apparatus, the combination with a combustion chamber and a gas burner located therein, of a mixer located within the heating apparatus in juxtaposition to the gas burner, and separate air and gas conduits leading from the exterior of the heating apparatus to the mixer whereby the supply of air and gas will be mixed in close proximity to the point of consumption.
5. In a heating apparatus, the combination with a combustion chamber and a gas burner located therein, of a diaphragm or baffle located within the combustion chamber substantially level with the burner.
6. In a heating apparatus, the combination with a combustion chamber of a diaphragm or bafile located within the combustion chamber, said diaphragm or baflle having an opening therein and a gas burner registering with said opening.
7. In a heating apparatus, the combination with a combustion chamber of a pair of elongated parallel gas burners therein, and a baflle or diaphragm within the combustion chamber, said bafile or diaphragm being elevated into a ridge like formation intermediate the burners.
8. In a heating apparatus, the combination with a combustion chamber of a pair of elongated parallel gas burners therein, a 'bafiie or diaphragm within the combustion chamber the medial portion of which is elevated into a ridge like formation intermediate the said burners, and a third burner located at the apex of said ridge like formation and above the level of said pair of burners.
In testimony whereof, I have hereunto set my hand this 12 day of March A. D. 1918.
