SETTING FOR STEAM-BOILERS.
SPECIFICATION forming part of Letters Patent No. 427,694, dated May 13, 1890.
Application filed August 9, 1889. Serial No. 320,274. (No model.)
To all whom, it maybonccrn:
Be it known that I, \VORICK O. J ONES, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and use fullmprovements inSettingforSteam-Boilers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to that class of steamboilers wherein an arch or diaphragm of refractory111aterial-such as fire-brick-is interposed between the fire-box and the under side of the boiler for the purpose of regenerating the heat and igniting the gases and unconsumed carbon.
The object of my invention is, first, to gain more space between the top of the fuel and the under side of the diaphragm in boilers using a fire-brick arch or diaphragm over the fire-box, whereby the igniting of the gases is more thoroughly effected; second, to deflect the burning gases from the center to the sides of the boiler, in order to distribute the heat more equally, and, third, to bring more of the surface of the boiler under the influence of the heat radiated from the upper side of the diaphragm. I attain these objects by means of the herein-described invention, which consists, essentially, of a boiler having a parti- -tion-wall of tire-brick or analogous material,
extending longitudinally through the firebox, whereby the grate is divided into sections and arches or diaphragms extending from the said partition to the side walls of the fire-box, the outer ends of said arches be ing on a higher level than the inner ends.
In the accompanying drawings I illustrate a boiler embodying my invention.
Figure 1 is a longitudinal vertical section through y 'y of Fig. 2, with the boiler proper in elevation. Fig. 2 is a section on m m of Fig. 1.
A is a cylindrical boiler.
G G are the walls, 0 the bridge-wall, and B the grate, all these parts being of any ordinary construction.
Vertically beneath the center of the boiler and extending longitudinally through the fire-box I build a partition-wall D of some refractory material, preferably of fire-brick. From the upper portion of this wall I spring two arches F over the fire-box and out against the side wall of the boiler. Each arch is in the form of a segment extending obliquely upward, the outer end being higher than the inner, and the upper surface of the arch passes, preferably, a short distance from the shell of theboiler. Extending longitudinally through the arches F are the air-ducts I, the outer ends of which communicate with openings in the front of the boiler, while theinner ends open into the furnace at the proper point to assist the combustion of the gases, preferably at the inner end of the arch. As here shown, the arches or diaphragms extend the length of the firebox; but I may extend them over the bridge-wall or the entire length of the boiler, if desired. Asa result of this construction'I obtain the following advantages over the old manner of constructing these boilers, viz: Higher space is formed between the grate and the diaphragm, whereby the gases are more thoroughly and completely burned. The gases as they rise and ignite in contact with the diaphragm, instead of passing along under the center of the boiler, as in the old form, where a single arch was used, are deflected and come up around the sides of the boiler, thus distributing the heat more evenly. The amount of heat radiated from the upper surface of the diaphragm to the boiler is also greatly increased by the arches located as here shown, since this radiation reach es well up on the side of the boiler, when with a single arch it was confined mostly to the bottom. The fire-brick partition aids the combustion of the gases after it becomes hot, and by dividing the grate into separate sections or compartments it makes it possible to manipulate the fires much more economically than when the fire was run in a single firebox. Thus one fire may be drawn Without putting out the other, and they may be fed alternately, thus preventing the boiler from cooling down when fresh fuel is applied. The air-ducts I, passing, as they do, through the intensely-heated arches, supply highlyheated air to the burning gases, and thus produce the most intense heat.
I claim- I The combination, With a cylindrical boiler,
boiler, and an arch or diaphragm extending from said partition outward to the side of said furnace, the outer end of said arch or dia- 15 phragni being at a higher level than the inner end, substantially as shown.
In testimony whereof I affix my signature in presence of two Witnesses.
