Specification of Letters Patent.
Patented April 21, 1908.
Application filed October 25, 1906. Serial No. 340,601.
To all whom it may concern:
Be 1t known that I, HENRY P. BRADBURY,
r a citizen of the United States,-residing at Springfield, in the county of Clark and State 0 Ohio, have invented certain new and useful Improvements in Smoke-Consumers, of which the following is a specification.
My invention relates to smoke consumers and is particularly adapted for use in connection with steam boilers but may be used in connection with other devices.
The objectof the invention is to greatly simplify the construction as wellas the means and mode of operation of such devices whereby they will not only prevent the escape of smoke from the stack or chimney but will prevent the accumulation of soot and other products of combustion within the stack and the boiler setting.
A further object of the invention is to provide means for consuming the particles of carbon and combustible gasesset free during the process of burning coal and which are usually lost by their escape through the flue or the chimney.
A further object of the invention is to provide means for burning the smoke and gas at the oint'of greatest advantage, that is, where t e heat may be used for heating the 3 boiler or for other purposes.
With the above primary and other incidental objects in view, as will appear from the specification, the invention consists of the means, construction, devices and mode of operation, or their equivalents, hereinafter described and set forth in the claims.
- In the drawings, Figure I is a sectional View of a boiler setting showing the boiler, the fire-box and the auxiliary fire-box. Fig.
40 2 is a perspective view-ofthe boiler setting extended rearwardly and slighglg together with a portion of' the stack, the blower and conduit hereinafter described. .Fig. 3 is a plan view showing the relation of the stack'and conduit and blower, or rotary Referringbby letter to the drawings, a represents the oiler, a the stack. a is the usual boiler setting.
7 a is a fire-box; a the ashit below it. I
a, is the bridge wall. T e bridge wall is upwardly, the bridge .as at af. Immediatcly back wall, a intermediate said bridge wall, a
and a supplemental bridge wall, a, and below the extension, a, is located an auxiliary firebox, I). The fire-box, a is ada ted to burn either coal or slack, or other fue of the ordinary type. Within the auxiliary fire-box, b, is preferably used coke, although other kinds of fuel may be successfully employed. A rotary fan or blower, b, is provided having a conduit, bflleading therefrom and discharging intothe ash-pit, 6 below the auxiliary forces a constant stream of air through the conduit, 5 to the ash-pit, if, of the auxiliary fire-box, b, and by suction through the conduit, 1), draws from the stack, a, the hot gases and such smoke as may be passed to the stack, causing said smoke and gases to be returned through the conduit, b", to the ashfplit, b thence passing through the hot coke re to again pass through the same channels as before. The hot gases and smoke drawn from the stack through the conduit, 1), will warm the air in the conduit, b which has been taken in through the rotary fan, I), so that .the current of air passing through the auxiliary fire box, I), from the conduit, b will in no way chill the smoke to form soot, nor
will itchill the boiler or any adjacent parts,
but will supply a constant stream of oxygen to be mixed with the gases released from the coal in the fire-box, a and will form therewith a combustible mixture which will burn with intense heat at the point, 0, the exit from the auxiliary fire box, 1), between the rear extension, a, and supplemental bridge wall, a. Any gases which may escape combustion atv this point will be again returned through the conduit, 6 with an additional supply of warm fresh air.
The extension, a, of the bridge wall, a as before stated, is extended rearwardly and slightly upwardly, and this extension is of such shape and thickness that it gives direction to the ases and products of combustion from both rnaces, so that they are flowing in substantially the same direction wherethey come together at or near the point c. This extension of the bridge Well also becomes hot and tends to further he'etthe gases" from the main furnace as they assover the same, so that the combustion at this pointis as erfect as can be secured.
x mm the above description it Will-be epparent that there hesbeen produced it construction in which a constant sup iy cfexyen Wiil be provided to mix ne'th t e. gases 1-seased in the primary fire box to forms coin bustible mixture, which will burn-at emost advantageous point, and that the snpniy of oxygen thus provided will be snfiicientiy heetedlthet it Wih in no wise chill the smoke to for-Insect Within the structure, nor wiii it chill the beiier or any adjecentfpertsg. it is further obvious that the constrnctisn described wiii in no Way retard the-flew of the smoke or gwes', nor will it'i'nteriere Wither retard the dreit, but to the contreiy, through. v
the conduit, 5", from the stack, efltviii ecceier-j ate the dreft. it is e parent that throughtheacceleration of the sit and the burning of the sses below the boiler that the efiicienc will e greatly increased.
It 18 obvious that the structure is SUSGQ/pr' tibie of modiiioetien in its form, proportion, detailed construction and arrangement of perts Without departing from the principle involved or sacrificing any of its advantages. i do not, therefore, limit myself to the exact construction shown and described.
Having thus described my invention, 1-
1. in a construction such as described, a plurality of fire-boxes, e dividing Wei separating one fire-box from the other, one fire-- box being at the rear of'the 'otherin the line of draft, e refractory roof extending rear- Werdiy from thedividing Wall and projecting over the reer firebox, a passageay formed by an opening in the refractory roof and near seems the rear end thereoffor the assege ,o'f' -the" products of combustion, a; we :formed above the openingfor causing the. flames from 3 the fire-boxes toteke'a, rearward course.
productsof combustion, '9; well formed above the opening for causing the flames from the fire-boxes to take a 'reerwerd course, and means for'forcing a draft .throughsaid passe%e-wey away from the fire boxes, substantia iy es-speoified. v 4
3. lne construction such as described, a pinrshty oi'fiIe-bexes, is dividing Well separetingfone fire-.boxfrom" the other, one firebox being at the rear of the other'in' the'lin'e' of, arse, a refractory 'roof extending reap wsrdlyfiem the dividing Well and pro eating over the rear fire-box, e passage-way formed byen opening in. the refrectory roof and near the-rear end thereof for the assege of the products of combustion, e Wei formed above the opening 'for causing the flames from the fire-boxes to take a rearward course, and Y means foriming a draft, through said passage-Way away from the,fire-boxes, 'a stack end a ism for fencing a draft from said stack, and a pesse 'e-Wey' connecting the fan With the rear fire 05:, substantially as specified.
In testimony whereof, I have hereunto set my hand this 22nd day of October A. D.-
