SPECIFICATION forming part of Letters Patent No.`717,582, dated January 6, 1903.
Application filed March 4, 1902.
To @ZZ whom, it may concern,.-
Be it known that I, HENRY EDMUND KENT, a citizen of the United States, and a resident of f Bualmin the county of Erie and State ofNeW York, have invented a new and Im proved Furnace, of which the followingis af ull, clear, and exact description.
The object of the invention is to provide a new and improved furnace arranged to inio sure complete combustion of the fuel and the extraction of allthe heat units contained in the fuel, producing thereby an extremely high heat for use in steam -generatiom smelting operations, and for various other purposes.
The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of theinvention is zo represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure l is a sectional side elevation of the improvement as applied to a steamboiler. Fig. 2 is a plan view of the improvement as applied to a smelting-oven. Fig. 3 is an enlarged sectional side elevation of the same on the line 3 3 of Fig. 2. Fig. -t is a perspective 3o View of the same. Fig. 5 is a side elevation of the perforate tube for the solid fuel-chamber. Fig. 6 is a plan View of the same. Fig. '7 is a side elevation of the conductor. Fig. 8 is a view of one end of the same, and Fig. 9
is a view of the other end thereof.
The fuel-chamber A is preferably in the form of a hollow frustum of. a cone, open at the top, and containing solid or hard fuel B such as coal, coke, peat, shale, lignite, as- 4c phaltum, wood, or the like-the fuel completely surrounding a perforate tube C, rising in the center of the chamber A, preferably built of asuitable refractory material or other material capable of withstanding a high heat.
The tube C may be built of bricks or the like, set in checker or cob-house form, and in to the lower end of this tube opens a steam-jet from a steam-supply pipe D, connected with a steam-supply E, such as a steam-boiler, and
.smelter-oven H, as illustrated in Figs. 2, 3,
5o from the upper end of the tube C leads a tu- Serial No. 96,587. ma model bularcouductor F, gradually contracting and curved, to lead out of the chamber A to one side thereof and into the fire-box Gr of the steam-boiler E, as shown in Fig. l, or to a and 4, or to any other place where the heat of the oven is to be applied.
Now when the furnace is in operation the steam passing into the lower end of the perforate tube C causes a suction action therein, so that the fuel. B in the chamber A readily burns when ignited and the products of combustion pass through the perforations in the .tube C to the interior thereof to be forced upward by the action ofthe steam-jet and to mix with the steam to produce a highly-inammable mixture. This mixture passes into the conductor F, which conducts the mixture into the fire-box Grof the boiler E or into the smelter-oven H or otherplacein which the heat is to be used. Into the fire-box G opens a nozzle I', connected with an injector I, for conducting a flame of burning gaseous fuel, such as gas or a mixture of gas and steam, into the fire-box, adjacent to the delivery end of the conductor F, so that the highly-inflammable mixture from the conductor F is ignited and burns with the gaseous fuel in the fire-box G to cause not only a complete combustion of all the fuel'and extraction of all the heat units, but at the same time an extremely high heat is produced for quickly generating the steam in the boiler E or rapidly smelting the ores or other materials contained in the smelter-oven H.
In order to increase the suction action in the tube C, l may employ one or more branch steam-pipes D', leading from the steainfsup ply pipe D and opening into the conductor F to cause steam to pass into the said conductor in the direction in which the mixture is-t'ravcling, so that the mixture passes under a high pressure and at great velocity out of the conductor F, and at the same time the mixture is enriched with steam from the branch pipes D'.
The injector I in forcing a mixture of gaseous fuel and steam into the nozzle I causes air to pass into the said nozzle, (see Fig. 3,) and this mixture readily burns in the nozzle 10o .I and passes under considerable pressure into the fire-box G to burn with the mixture coming throughv the conductor F. The injector I is connected by a branch pipe D2 with the steam-supply pipe D and bya pipe J with a pump K, having its suction-pipe connected with a reservoir L, containing fuel-such as oil, gas, and the like-the pipe serving to pump the fuel through the pipe J into the injector I, in which the fuel mixes with the steam from the branch pipe D2 to form a highly-inflammable gas.
As shown in Fig. 2, the steam-boiler E supplies the pipe D with steam and also the pump K to actuate the latter.
The pipes D2 and .I are provided with suitable valves D3 J' to permit of properly regulating the amount of steam and gaseous fuel passing to the injector I.
It is evident that when the furnace is in operation all the smoke and gases arising from the burning of the solid or hard fuel in the chamber A are completely burned, and consequently chimneys and other similar drafttubes are completely dispensed with, and at the same time an extremely high heat is developed, so as to insure a quick generation of steam or smelting of ores and other materials.
I do not limit myself to the particular construction of the furnace shown and described, as the same may be varied Without deviating from the spirit of my invention.
IIa-ving .thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Afurnace having afuel-chamber open at the top, a perforate tube in the said chamber, a steam-jet opening into the tube, to create a suction action therein, to draw the products of combustion from the burning fuel through the perforations into the tube, and a tubular conductor secured to one end of said tube for leading the products of combustion and the steam mixed therewith to a re-box or the like, as set forth.
2. A furnace having a fuel-chamber open at the top and closed at the bottom, a perforate tube rising centrally in the said chamber and surrounded by the burning fuel, a steamjet connected with a steam-supply and opening into the lower end of the said perforate tube, to create a suction action therein, to draw the products of combustion from the burning fuel through the perforations into the tube, and a conductor connected with the upper end of the perforated tube, as set forth. l
3. A furnace having a fuel-chamber in the form of a hollow frustum of a cone, said chamber being open at the top and closed at the bottom, a vertical perforate tube in said chamber and surrounded by the burning fuel therein, a steam-jet opening into the lower end of the tube, to create a suction action therein, to draw the products of combustion from the surrounding burning fuel into the said tube, and a tapering tubular conductor connected with the upper end of the perforated tube, as
Vset forth.
4. A furnace having a perforate tube, surrounded by the burning fuel, a steam-jet opening into one end of the tube, to create a suction action therein, to draw the products of combustion from the surrounding burning fuel into the said tube, a conductor connected with the discharge end of the said perforate tube, a {ire-box into which the conductor discharges, and an injector for delivering to the mixture issuing from the conductor a gaseous fuel, as set forth.
