ATTORNEY GHLES D. EZQSH, OF NEW YORK, N. Y.
summon Application filed (Pctober 20, 1919, Serial Ito. 332
To all whom it 721a concern:
Be itknown that 1, CHARLES D. MosHnn, a citizen of the United States, residing at ew York city, in the county of New York and State-of New York, have invented certam new and useful Improvements in Furnaces, of which the fol owing is a specification, reference being had. therein to the ac companying drawing.
y invention relates to improvements in supplementary combustion chambers and more particularly has reference to a conical form of combustionchamber adapted for attachment to a steam boiler outfit such as a Scotch boiler, and may be used in addition to theusual coal burning furnaces.
eferring to the accompanying-drawings,
I have illustrated in Fig. 1 in front elevation a suitable form of Scotch boiler and furnace showing an application of my inven: tion. Fig. 2 is a longitudinal vertical sectional elevation of the same. Fig. 3 is an enlarged longitudinalcross-sectional view on the line. 3-3 of Fig. 1 illustrating the conical combustion chamber adapted for burning oil, gas or other combustible. Fig. 4: is a view looking from left to right perforated damper plates hereinafter more fully described, and Fig. 5 isa plan view looking down upon one of the fire brick segments of the conical chamber.
Referring now more particularly to Figs. 1 and 2, 6 indicates the outer walls of the boiler and furnace, and 7 the usual boiler tubes thereof, 8 indicating the air heating tubes within the flue 9 of the conventional form of Scotch boiler. 10 indicates the supplementary conical combustion chamber shown to better advantage in Fig. 3.
Referring now more particularly to Figs. 3 to 5 inclusive, it will be observed that eight or any other convenient number of segments of fire brick or other suitable material, indicated by the reference character 11 may be joined together ture adapted to be retained by the corrugated band 12 which may be'bolted together in sections as indicated at 13,the corrugations or buckling such as 14: being intended to contribute resiliency, or yielding to accommodate expansion, etc. This band may be secured adjacent the larger periphery of the conical combustion chamber as indicated at 15in Fig. 3. The smaller periphery of said conical chamber may also be secured by a suitable corrugated band such as 16. 17 in- Specification of Letters Patent.
at the d forming a conical strucli atented llllar. 28, 322. ,933'. Renewed July 12, 1921. Serial. No. i-84,193.
dicates the holes through the various sections of the fire brick or other refractory material which holes are preferably substantially rectangular in the slots as shown to better advantage in Fig. 4 upon the outside, and are preferably formed as round holes upon the inside as indicated at 18 in Fig. 3.
19 indicates curved with elongated slots with e ongated slots plates also perforated 20 adapted to register 17 upon the outside of are preferably adapted to fit over the outside of the fire brick sections as shown in Fig. 3 being separated and guided in the bands 21, so that the said conical rings or dampers being provided with a suitable rack 22 may be rotated by pinions such as 2323-23 which may be operated by a suitable tool such as the crank handle 24:.
he burner for the indicated by reference character 25 and so mounted as to deliver the charge of fuel through the cap 26 which may be secured by any suitable means such as bolts 27 to the anged rings 28 securedby the angle rings 29 to the front wall 30 of the chamber.
eferring now more particularly to Fig. 2, it will be seen that the air passing through the heating tubes 8 to the chamber 31 enters the chamber 32 where it is drawn or forced by a blower or other suitable means through the elongated slots 20 of the damper plates and through the elongated slots 17 of the conical the brick structure into the tion chamber 10where it is met by the inrushing spray of fuel 33 and is consumed. y providing separate dampers at different points along the longitude of the conical chamber, it will be readily appreciated the' the mixture of fuel at said points thereby providing for a wide rang v of adjustment for the mixture of the el and insuringga. proper and complete, as'well as uniform distribution and combustion of the fuel as it passes through the furnace beneath the boiler tubes.
34 indicates a suitable hole or port cut through the wall of the chamber 26, and 35 indicates a suitable transparent cover p otally hinged beneath the screw 36 adapted to close said hole but through which the interior of the chamber 26 may be observed, J
which also provides an opening for igniting the fuel when starting up. The perforated form of elongated.
combuscombustible material is bricks eventually become heated to a high temperature causing the jets of air in passing through them to be highly heated when ignition continues as long as fuel and air is supplied in proper amounts.
Of course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention.
I claim:
1. In a combustion chamber of the class described, a conical chamber of incombustible material with air openings and a damper adjacent the exterior surface thereof for controlling the mixture of air and fuel therein, said openings arranged radially around a burner or source of fuel supply for jets of air to enter the conical chamber in approximately the opposite-direction of the incoming fuel with a projection between the circular rows of holes to prevent or baffle the fuel from entering said air openings.
2. In a combustion chamber of the class described, a conical chamber of incombustible material, a burner adapted to supply fuel in cone-like formation, means for supplying tangential air jets around said burner said air jets being adapted to enter the conical chamber in approximately the opposite direction to the incoming fue 3. In a combustion chamber of the class described, a conical chamber of incombustible material, a burner for supplying fuel in cone-like formation, openings around said burner for admitting air tangentially, said air openings through said conical chamber and pointing approximately in a direction opposite to the incoming whirling fuel, and
a ledge between the circular rows of air openings forming grooves around the interior of the conical chamber, said air openings at the apex of said grooves, and the ledge at the baseof said grooves forming a baffle to deflect the current of fuel from entering the said air openings.
4. In a vcombustion chamber of the class described, sections of incombustible material forming a conical chamber, and a damper adjacent the side thereof for controlling the fuel mixture, saiddamper being adapted to be controlled in sections.
5. In a combustion chamber of the class described, sectionsof incombustible material forming a conical chamber, and a damper adjacent the side thereof for controlling the fuel mixture, said sections having perforations extending radially therethrough, said perforations substantially rectangular at the, outer surface and substantially'circular at the inner surface.-
In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
