EDWIN J. ELMS, OF CHELSEA, MASSACHUSETTS.-
STEAM-BOILER FURNACE.
SPECIFICATION forming part of Letters Patent No. 607,738, dated July 19, 1898. Application filed March 28, 1898. Serial No. 675,419. (No model.)
To all whom it may concern:
Be it known that I, EDWIN J. ELMS, a citizen of the United States, residing at Chelsea, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Steam Boiler Furnaces, of which the following is a specification.
This invention relates to a novel construction whereby a jet of steam injected into an air-pipe by the action of an automatic damperregulator introduces air in numerous small jets into the furnace, discharging it in a heated condition thereinto at or near the points where the light gases pass over the bridge-wall and under the back arch, thereby aiding combustion by mingling with the gases the warm air drawn into the furnace by the steam-jet.
The nature of the invention is fully described in detail below, and illustrated in the accompanying drawings, in which- Figure l is a side elevation of a steamboiler furnace embodying my invention. Fig. 2 is a longitudinal section showing the boiler in elevation. Fig. 3 is a horizontal section of the furnace. Fig. 4 is a transverse vertical section taken on line 4, Fig. 1.
Similar letters of reference indicate corresponding parts.
A represents the boiler; 13, the sides of the furnace; O, the bridge-wall; G, the back arch, and G" the rear wall.
a is the fire-space.
D is a pipe leading from the external air to the vertical pipe E, which extends into the coupling F, leading into and uniting the oppositely-extending horizontal pipes H and H, which are connected by the couplings h and h with the horizontal pipes K and K, which extend through the side 13 andinto the bridgewall 0 and back arch O, as indicated in Fig. 3. These pipes are located near the rear side of the bridge-wall and the front side of the back arch and are provided with a series of small jetpipes or nozzles which extend through said walls into the furnace under the boiler. The nozzles or jet-pipes L extend from the pipe K through the rear surface of the bridge-wall and are set, preferably, at an upward angle, as indicated in Fig. 2. The nozzles or jet-pipes L extend from the pipe K through the front side of the back' arch in Fig. l as broken out) is open, and extending verticallythrough such opening is the upturned nozzle or discharge end P of a steam-pipe, which, with its necessary couplings, is lettered P. This pipe extends hori zontally along the outer side of the Wall B, thence vertically upward, and thence horizontally, connecting at P with the boiler, from which it takes steam. The damper b, Fig. 2, is connected by a suitable leverb and chain 19 with a damper-regulator cl, operated by an ordinary diaphragm in the case 6, all substantially as illustrated in Figs. 1 and 4. This automatic damper-regulating device is common and needs no explanation. A suit able hand-regulator may be placed at S in the pipe P between the damper-regulator and -nozzle.
. The operation of the device is as follows: When the automatic damper-regulator is in such a position as to allow the steam from the boiler to pass through the pipe P, such steam is injected by the nozzle P into the lower end of the pipe E, into which the air-pipe D opens, with the effect of drawing the air by a wellknown principle from the pipe D into the pipe E and through the branching pipes H H into the pipes K K, and through the small pipes L L into' the furnace next the upper part of the bridge-wall and the lower part of the back arch. Thus the air is injected into the flames and mingles with the gases in numerous small jets warmed by the steam from the pipe P. By means of these numerous small jets of warm air injected into the furnace at the most favorable points the air and gases mingle, with the effect of greatly aiding combustion.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In a steam-boiler furnace, a pipe leading from the external air through the masonry of the furnace; a plurality of small jetpipes connecting said pipe with the combus= tion-chamber under the boiler at or near the bridge-wall; a steam-pipe connected with the boiler and extending outside of the furnace to said air-pipe a nozzle extending from said steam-pipe into the air-pipe; and a damperregulator intermediate of the damper and the steam-pipe, wherebya plurality of small jets of air are automatically forced into the combustion-chainber, substantially as set forth.
2. In a steam-boiler furnace, in combination, the boiler, and masonry provided with the bridgeall O and back arch O; the pipes K, K extending substantially horizontally into said bridge-Wall and back arch; a plurality of small jet-pipes leading from said pipes K,K into the combustion-chamber; the pipes H, H connected With the outer ends of EDVIN J. ELMS.
