SMOKE-CONSUMING DEVICE FOR FURNACES.
SPECIFICATION forming part of Letters Patent N o. 667,126, dated January 29, 1901.
Application iled June 9, 1900.
To all whom t may concern:
Be it known that I, GEORGE S. GALLAGHER, a citizen of the United States, residing at the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Smoke-Consuming Devices for Furnaces, of which the following is a specification.
My present invention is designed as an improvement upon the device shown and described in my former application for Letters Patent, Serial No. 1,039, iiled January 11, 1900, allowed April 30, 1900. In the device of said application iiues were made in the side and front walls and bridge-wall of the furnace, with connecting-throats and aseries of openings. Pipes for air were placed in said flues and injector-nozzles therefrom in the series of openings, and in the action of said device the smoke and unconsu med gases were drawn oif the fire and forced back with an abundant supply of air to be consumed in the I combustion-chamber under the boiler. In my present invention I continue the systemof my aforesaid application and provide fines in the opposite side or face of the bridge-wall and in the side walls of the furnace beyond and back of the bridge-wall, and I throw over an arch beneath the boiler beyond and back of the bridge-wall, and said lues are provided with series of openings, with pipes for air and injector-nozzles in the series of openings. The products of combustion are obliged to pass rearward from the fire beneath the boiler over the bridge-wall and down beneath the arch, and any unconsumed or imperfectlyconsumed gases or smoke passing over the bridge-wall meet the air forced from the flues and nozzles between the bridge-wall and the arch, where the same are consumed, so that a perfect combustion results.
In the drawings, Figure 1 is a longitudinal section through the lower part of the boiler and walls from the front rearward, and Fig. 2 is a sectional plan of the same below the line of the boiler.
The side walls c a, the front wall b, and the Serial No. 19,666. (No model.)
`bridge-wall c, together with the foundation thereof, are preferably built, as usual, of brick, and the grate-bars d are supported in any desired manner. The front wall of the furnace is provided with fu el-doors 2 and ashdoors 3, and the ash-pit cis, as usual, below the grate-bars d. I prefel-,as set forth in my aforesaid application,toemploy iuesf,g,and h,run ning horizontally and lengthwise of the walls, and to employ throats, as g' h', in the side walls and as f' in the front wall above the level of the grate-bars and connecting with the lues f, g, and h, and in said flues fg h I place a pipe for air under pressure,whieh pipe is provided with injector-nozzles projectingthrough series of openings connecting the lines with the combustion-chamber. In my present improvement a main pipe lc enters from the rear about midway between the side walls above the foundation and passes up into the bridgewall and is provided with lateral horizontal branches lo', extending in opposite directions through the flue QI of the bridge-wall. The ends of the pipe lo are provided with T-couplings, and from these the longitudinal branch pipes k2 extend forward through the Iiues h and g, one of said pipes passing around and through the front flue f. The pipes k2 are provided with injector-nozzles extending out `through series of openings, as shown in the drawings and as described in my aforesaid application.
The flue in the bridge-wall is preferably provided with one or more throats t', performing a similar office to the throats f', g', and h of my said application and for the purpose of drawing the smoke and unconsulned gases off the fire and forcing the same, with an abundant supply of air, back into the combustion-chamber to be consumed between the bridge-wall and the front and side walls beneath the boiler. In my present improvement the bridge-wall is provided with a series of openings extending in both directions toward both faces of the said wall and connecting the iiue 1l with the chambers at either side of the wall, and the branch pipes 7c are provided with series of injector-nozzles projecting into the said openings.
An arch n is provided or thrown over beneath the boiler and rearward of the bridgewall c, and between the arch and the bridgewall in the side walls a I provide tlues Z m for the longitudinal rearward branch pipes k3, that connect with the couplings of the pipes 7d, and these tlues Z mare also provided with a series of openings for injector-nozzles connected to the pipes 7c3, so that air under pressure forced through the pipe k passes through pipes k c2 k3 and all the injector-nozzles connected therewith. From some of the nozzles the air passes into the combustion-chamber and from thence into the chamber between the bridge-wall and the arch. The operation of the device is similar to that set forth in my aforesaid application and as herein before intimated. Theproductsofcombustionfrom the main chamber under the boiler between the side and front walls and the bridge-wall pass over the bridge-wall and down beneath the arch to the rear of the boiler, and should there be any unconsumed gases or smoke or partiallysconsumed gases passing over the bridge-wall the same are met with an abundant supply ot' air in the chamber beneath the boiler between the side walls, the bridgewall, and the arch with the object of fully consuming the said gases or smoke and effecting a perfect combustion, so that none of the units of heat are wasted, but all are utilized.
The tlues Z m and the series of openings connecting the same with the chamber back ofthe bridge-wall are formed for the purpose of holding the pipes 7a3 and the injectornozzles connected therewith. rlhe throat or throats t" communicate with the flue i through the bridge-wall and the smoke and unconsumed gases passing through these throats might appear to pass freely in opposite directions into both chambers through the series of openings, to overcome which I may iind it advantageous to partially or wholly close off the possibility of the said products of combustion and smoke passing rearward into the chamber behind or back of the bridge-wall, and so compel the same to be entirely thrown forward over the grate-bars and fuel.
The injector-nozzles projecting from the pipes 7c' Z22 through the series of openings sur- .rounding the fire-chamber may by preference be of larger area, and consequently greater capacit-y than the injector-nozzles projecting from the pipes Zt' k3 through the series of openings on three sides of the chamber between the arch, sides, and bridge-wall, so as to insure the smoke and gases being drawn oif the fire and projected with an abundant supply of air into the chamber over the fire, as an abundant supply of air is more essential in the fire-chamber than rearward of the bridgewall.
I claim as my inventionl. The combination in a smoke-consuming furnace with dues placed horizontally in the walls, and series of openings connecting the same with the fire-chamber and pipes for air under pressure in said Iiues and injector-nozzles in said openings, of an arch beneath the boiler and rearward of the bridge-wall, tlues in the side walls between the bridge-wall and the arch, and series of openings connecting the said tlues with the chamber between the bridge-wall and the arch, and pipes for air undel' pressure in said iues and injectornozzles in said openings, substantially as set forth.

3. The combination in a smoke-consuming furnace, with the side walls, the bridge-wall and an arch beneath the boiler and rearward of the bridge-wall and the grate-bars whereby a combustion-chamber is formed above the grate-bars and another chamber between the bridge-wall and the arch, of lines in the side walls and in the bridge-wall, and series of openings connecting said lines with both of said chambers, a pipe for air under pressure coming up through the bridge wall with branches extending in both directions through the iue of the bridge-wall into the side walls and with other branches extending bot-h forward and rearward through the iiues in the side walls, and injector-nozzles extending from said pipes into said series of openings whereby air is forced from said pipes simultaneously into both chambers of the furnace, substantially as set forth.
