IMPRDVEMENT IN BOlLER-SETTINGS.
Specification forming part of Letters Patent No. 1 89,862, dated April 24, 1877; application filed March 7, 1877.
To all whom t may concern:
Be it known that I, KINGSBURY M. JARVIS, of Peabody, in the county of Essex and State of Massachusetts, have invented Improvements in Boiler-Setting, of which the following is aspecication This invention relates to gas-consuming furnaces for steam-boilers; and is an improvement on United States Letters Patent No. 176,639 and No. 136,734, heretofore. granted to me, and to which reference may be had.
The object of this present invention is to improve the furnaces described and represented in such former patents, so as in a greater degree to heat the air introduced to complete the combustion of the fuel and gases evolved during the process o'f combustion.
In this invention I utilize the bridge-Wall and the back'of the furnace, as well as the side walls, for the heating of the air to be discharged into the combustion-chamber.
Figure 1 represents, in sectional elevation, the side wall of a boiler-setting or furnace 5 Fig. 2, a View, looking from the front of the furnace, showing the air-passages in the back wall and bridge-wall; Fig. 3, a modification, and Fig. 4 a section, of bridge-Wall and bottom of combustion-chamber.
The greater portion of the side walls are made double, and, as shown in Fig. 1, are connected together back of the bridge-wall by means of ties b, preferably bricks, leaving a large space, c. A
These ties may be of any desired number.
Instead of these ties I may use horizontal lues or passages, they, in such case, running horizontally, as denoted in dotted lines d, connecting the ties, or the ues may run in other well-known directions therein. The'back wall has formed therein ducts ef, each communieating with the air-space in the side Wall next to it by a passage, g. The ducts ef communicate, at bottom, with the tapering tubes h,
common to my Patent No. 186,734, such tubes.
opening into the chamber i, under the perforated plate j, back of the bridge-wall k. Air entering the flue l, communicating `with the atmosphere, (shown at the front, but it may be at the back part of the setting or wall,) ilows through the chamber c or dues in the side wall, thence into the passage g, through ducts e, as denoted by arrows, thence into the tapering pipes. The air, as it is heated, being allowed to expand, and delivered into the chamber i, it rises through the perforated plate and into the gases passing over it.
The bridge-wall is provided with bridgewall ducts m a. Air entering the ducts o will pass into ducts n back along the duct lm, and thence along the duct p leading in a tortuous direction to the opening r, from which it is discharged, in a highly-heated state, into the combustion chamber near the bridge wall. Instead of the duct m leading into the vertical part of the duct p, as in Fig. 1, it may j lead into the part s, as in Fig. 3, and thence ultimately down the passage p, through au opening, t, leading therefrom into the combustion-chamber near the bridge-wall. The long ducts and passages herein referred to will all, preferably, be made to increase in area from their air-receiving to theirair-discharging mouths or passages, to aord ample space for the expansion of the air as it is heated.
The boiler may be of any usual construction, and it will be set above, and with reference to the grate, bridge-wall, and flame-bed, substantially as described in Patent 186,734..
The coal or other fuel rests against the bridge-Wall, and, by reason of the ducts therein, I am enabled to heat the air passing through such ducts very hot. The duct m might lead through a shorter duct than duct p, into the combustion-chamber.
The perforated plate, instead of being made of iron, may be made of fire-brick material, and so, also, the flame-bed, pipes, or ducts.
lol-aim- 1. The combination, with the side and bridge walls, of ducts leading from the passages in the side Walls into and out from the bridgewall and into the side wall and combustionchamber, to heat the air passing through such bridge-Wall ducts, substantially as described.
2. The ducts m n in the bridgewall, in combination with the duct 10, and opening in the side wall opposite the combustion-chamber, substantially as described.
3. The ducts in the back of the wall, substantially as at e, in combination with the tapering pipes or fines, substantially as de- In testimony whereof I have signed my scribed. name to this specification in the presence of 4. The side wail, provided with its air-pastwo subscribing witnesses.
