SPECIFICATION forming part of Letters Patent No. 766,347, dated. August 2, 1904.
Application filed March 16, 1904. Serial No. 198,511. (No model.)
To all whom, it nmy concern:
Be it known that I, WILLIAM HENTsonEL, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Furnaces, of which the following is a specification.
This invention is an improved furnace particularly suitable for steam-boilers and provided with means for feeding air to the smoke and hot gases behind the fire-wall, whereby said fresh air will combine with the smoke and the gases and create the combustion of the carbon particles of which the smoke is formed, thereby acting as a smoke-consumer.
The object of the invention is to produce an improved furnace of the kind stated characterized particularly by novelty with respect to the means for feeding air to the gases.
In the accompanying drawings, Figure 1 is a longitudinal vertical section. Fig. 2 is a vertical cross-section. Fig. 3 is a horizontal section.
Referring specifically to the drawings, g indicates the fire-door, Z) the grate, f the flue or fireway above the bridge-wall (Z, a the boiler, and the side and end walls of the furnace.
Behind the bridge-wall are two cross-walls (a, one of which is located against the bridgewall and the other at a distance therefrom toward the rear end of the furnace. These walls are similar in construction, except that the one nearest the bridge-wall is somewhat higher than the other. These walls are hollow, as at c, which is a longitudinal passage extending lengthwise of the wall near the top thereof. This passage communicates with the smoke and gas chamber through the rearwardly-directed openings h. Air is supplied to said passage by means of an underground pipe 0, communicating with the valve-opening joutside the walls of the furnace. The valve j may be adjusted to regulate the amount of air end wall.
admitted. In Fig. 3 a modification is indidicated, wherein the pipe 0 extends out under the side wall of the furnace in addition to the This is a mere matter of convenience, and the pipe may be extended outside the wall in any direction.
Another means of supplying air to the combustion-chamber back of the fire-wall is by means of a cross pipe 1', which extends through the side wall of the furnace and the opening to which is controlled by a valve, (indicated at 7",) and the pipe has in the combustion-chamber openings 1 through which air may be fed into the furnace.
In operation the draft of the furnace draws in air through the pipes and passages shown, and the same is discharged in an effective position to combine with the gases and carbon particles, thereby increasing combustion and also decreasing the amount of smoke. The novel parts can be applied to existing furnaces without great difficulty and comprise a simple and efiicient means for feeding air to the rear part of a furnace for the purpose intended.
Vhat I claim as new, and desire to secure by Letters Patent, is
In a steam-boiler furnace, a plurality of walls 0, extending across the combustionchamber behind the fire-wall, one of said walls being adjacent the fire-wall and the other being at a distance therefrom, said walls having longitudinal air-passages with rearwardly-directed openings into the said chamber, and a perforated air-pipe 1', extending through the furnace-wall and across under the boiler between the side walls (a.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
