PHILIP GEYER, OF NEWARK, NElV JERSEY.
FURNACE.
SPECIFICATION forming part of Letters IPatent No.425,170, dated April 8, 1890.
Application filed August 26, 1839.
To aZZ whom, it may concern:
Be it known that I, PHILIP GEYER, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Furnaces, of which the following is a full, clear, and exact description.
My invention relates to an improvement in furnaces, and has for its object to provide a means whereby the products of combustion which are usually permitted to escape are returned over and beneath the grate-bars and the gases contained in said products consumed, thereby greatly economizing in fuel.
A further object of the invention is to provide a means whereby a portion of the waste products of combustion may be returned to the fire and a portion utilized to heat the fresh-air supply for the boiler.
Another object of the invention is to provide a means for heating the fresh-air supply and dampening the products of combustion before they escape through the standpipes, whereby the bulk of the products of combustion are rendered heavy and lay in the base-chamber 20 for removal, thereby preventing the marring or disfigurement of the buildings which may be in the vicinity of the boiler.
The object of the invention is also to set the boiler in a substantial and simple manner, the setting being so constructed as to provide fiues capable of bringing about the above-named results.
The invention consists in the novel constructi on and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification,
in which similar figures of reference indicate corresponding parts in all the views.
Figure 1 is a central vertical section through the boiler and setting, the said section being taken on lines 1 1 of Figs. 2 and 3. Fig. 2 is a horizontal section on line 2 2 of Fig. 1, and
Fig. 3 is a vertical transverse section on line 3 3 of Fig. 1. Fig. 4. is apartial longitudinal section through one of the side flues 31, illustrating the application of the damper thereto.
The boiler 10 is supported in the side walls 11., of masonry, in substantially the usual Serial No. 321,957. (No model.)
Between the rear end of the boiler, abovethe tubes therein and the rear wall, a horizontal wall 16 is constructed, whereby the usual lower fire-flue 17 is obtained and the upper delivery-flue 18, which delivery-fine extends downward in front of the boiler, as best shown in Fig. 1, and at the lower end of the fire-flue 17 a perpendicular transverse wall 19 is constructed of less height than the height of said fire-flue, as is also best illustrated in Fig. 1.
The chimney 15 is provided with a basechamber 20, covered, preferably, by a metal cap-plate 21, and beneath the horizontal wall 11 an air-supply chamber 22 isformed, extending from one side wall to the other, which air-supply chamber connects with the chimney above the plate 21. Near the connection with the air-supply chamber and the chimney in the former an arch 23 is built, containing a central opening 24, the said arch being adapted to support the horizontal wall 11, and in the opening. of the arch a fan 25,0f any approved construction, is held to revolve, the shaft 26, upon which the fan is secured, being projected through the rear wall of the setting and provided at its outer end with drive-pulleys 27. This air-supply chamber not only connects with the chimney, but also has a direct and uninterrupted communication with the fire box beneath the grate-bars.
In the chimney a series of perpendicular tubes 28 are grouped, which tubes extend from top to bottom of said end fiue, their lower ends extending through the cap-plate 21 into the chamber 20, their upper ends being preferably held in position by an upper cap-plate 29, through which they extend.
Between the upper surface of the chimney and the contiguous face of the upper capplate, at the sides and ends of the former,
Into the base-chamber 20 of the chimney one or more pipes 39 are laid, adapted to convey exhaust-steam, when desired, into said chamber, and each of the side flues 3i and 2 is provided with a damper t0, controlled from the outer side of the setting.
In operation the [an 2-3 draws the fresh heated air downward through the chimney and forces the said air through the supply chamber 22 under and through the gratebars 13 to promote combustion. The pro ducts of combustion pass beneath the boiler through the fire-flue 17 into the rear ends of the fire-tubes ol? the boiler, out through the forward ends of said tubes, and upward in front of and over the boiler through the delivery-flue 18. The fan 36, revolving rapidly in its arch-opening, forces the products of combustion from the delivery-flue into the upper flue 33, connecting the side flues 31 and 32. The said products of combustion now pass down the said side fines 231 and 32, the amount to be passed through each side llue being regulated by the position of the dampers t0. Thus a great amount of the waste products of combustion are returned to the fire-box over the grate-bars through the fines 31, finding an exit at the outlet St. The re maining portion of the products of combustion, passing down the side flues 32, find an exit into the base-chamber 20 of the chimney, and from thence the said products of combustion pass upward through the tubes 28 out of the chimney, and if exhaust-steam is suf'l'cred to enter the chamber 20 it mingles with the ascending products of combustion, dampening the same, and effectually preventing the particles of soot, &c., from defacing surrounding buildings, as, being wet and therefore heavy, they will stay in the baseel1a1nber20,and if any should go out through the tubes 28 they will fall to the roof of the boiler-house as soon as they are freed from the tube.
It will be observed that the ascending waste products of combustion and exhauststeam effectually heat the tubes 28, and that the air-supply drawn in by the lower fan 25 in its downward passage must pass around and impinge upon these heated tubes, whereby the air-supply for the fire-box is heated to a high degree before being conveyed to the grate-bars.
By reason of the construction above set forth I utilize a maximum amount of the gases contained in the waste products of combustion, which have ordinarily been allowed to escape, and that portion of: the waste products of combustion not utilized is made to heat the draft-supply of the boiler.
At one side of the boilcr-setting, near the rear end, a box-like projection 7L1 is constructed, provided with a lid and a passage connecting with the chamber 20 at the base of the chimney, as illustrated in Figs. 2 and 3, whereby any sediment formed in. the said chamber may be readily extracted through the medium of this box-like projection.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Aboiler-setting provided with a chimney at one end, an air-supply flue connecting the chimney and the fire-box, and side ilues connecting the boiler delivery-flue with the firebox above the grate and the chimney, substantially as shown and described.
2. A boiler-setting provided with a chimney at one end, having a base-ehamber and tubes extending downward in said base-chamber, an air-supply iiue connecting the chimney and the lower portion of the ii re-box, and side lines united at their upper ends, connecting the boiler delivery-flue with the fire-box above the grate and the base-chamber of the chimney, substantially as shown and described.
3. A boiler-settin g provided with a chimney having a base-chamber andv tubes extending from said base-chamber upward, an air-supp] y flue eonncctin g the chimney and the fire-box beneath the grate, side lines united at their upper ends and provided. with dampers con necting the boiler delivery-flue with the firebox above the grate and the base-chamber oi the chimney, a fan held to revolve in the airsupply flue, and a second fan located in the boiler delivery-flue, substantially as and for the purpose specified.
4:. The combination, with a boiler, its setting, and the chimney, of an air-supply flue connecting the chimney and the fire-box, a
