CHARLES I3. THOMPSON, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE ILLINOIS HEATING COMPANY, OF SAME PLACE.
FU RNACAE.
SPECIFICATION forming part of Letters Patent NO. 533,569, dated February 5, 1895.
Application tiled May 29, 1894.
To all whom t may concern:
Beit known that I, CHARLES B. THOMPSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveiuvented certain new and useful Improvements in Furnaces, of which the following is a specification, reference being had to the accompanying drawings, in Which- Figure 1 is a vertical cross section on line I0 1-1 of Fig. 2. Fig. 2 is a Vertical section on line 2 2 of Fig. 1. Fig. 3 is ahorizontal section on line 3-3 of Fig. 1. Fig. 4 is a horizontal section on line et-t of Fig. 1.
My invention relates to furnaces, and has particularly to do with furnaces adapted for heating water for steam-heating purposes.
It has for its objects to provide for an improved circulation of water through the furnace; to provide a heating surface of increased 2o area; and to provide an improved construction whereby the draft of the furnace may be more perfectly regulated. I accomplish these objects as hereinafter specified and as illustrated in the drawings.
That which I regard as newr will be set forth in the claims.
In the drawings-5 indicates the fire-box, 6 the grate-bars, and '7 the ash-pit.
S indicates a water jacket which rests upon the base 9 of the furnace and forms the Wall of the fire-box 5, as shown in Figs. l and 2. Above the water jacket 8 are a number of annular fines 101112 arranged one above another and communicating by means of vertical ues 13--14-141 as best shown in Figs. 1 and et. The flue 15 is preferably arranged at the rear of the furnace opposite the turnace door 16, the iiues 13-14 being arranged about one hundred and twenty degrees from 40 the flue 15 at opposite sides of the furnace,
as shown in Fig. 4.. The nues 13-14 extend down to and communicate with the Water jacket 8, as indicated by dotted lines in Figs.
1 and 2, but the flue 15 does not communicate directly with such Water jacket.
17 indicates a number of tlues which extend transversely of the furnace in a horizontal position, affording communication between the opposite portions of the different annular iiues 10-11-12, as best shown in Fig. 2. The fines 17 are somewhat pear-shaped Serial No. 512,941 (No model.)
in cross section, the rounded portion being lowermost, as shown in Fig. 1. The flues 1'7 of each row are parallel- 0r substantially se-With each other, and the different rows are staggered, so that names and gases rising through a lower row of fines will be directed against the row nexthigher. By making the fines of the shape shown, a greater surface is exposed to the direct action of the Haines and 6o hot gases rising from the fire-box, and conse quently greater results are secured from the same heat than in any construction heretofore used; and by narrowing the upper portions of the fiues more direct channels are presented for the passage of the dames and a better draft may thereby be secured.
1 8 indicates a steam dome which is arranged at the upper portion of the furnace and is in communication with the annular flues 10- 7o 11-12 by means of the vertical flues 13- 14-15.
19 indicates an outlet pipe through which steam is conducted from the steam dome.
2O indicates a return pipe through which 75 Water from the condensation of the steam is returned to the rear portion of the water jacket 8, as shown in Fig. 2.
Water entering the rear portion ofthe water jacket 8 must pass around the irebox to the 8o passages 13-14 before it can rise, and consequently it is subjected to the directheat of the ire-box for a considerable length of time. After reaching the vertical fines 13-14 it rises to the various annular lues and thence 8 5 passes around the upper portion of the tirebox, the greater portion passing through the fines 17, where it is exposed to the heat of the furnace as above described. The steam generated is free to rise through the vertical 9o fines 13-.14-15 to the steam dome,and thence through the outlet pipe 19.
When a strong draft is desired the smoke and gases are conducted through the steam dome, through vertical passages 2l-22, to a 9 5 smoke chamber 3i at the top of the furnace, and thence to the smoke pipe 23. The smoke chamber 34: is formed by a top plate 33, the edges of which rest upon the top of the steam dome, as shown in Fig. 2. The smoke charnma ber 34 is cut off from the space between the outer casing 29 of the furnace and the outer wall ot' the furnace proper, by the top plate 33, except at two points, where openings are provided .in the top plate 33; one of said openings being shown in Fig. 2.
Vhen an indirect draft is desired the passages 21e-22 are closed by lids 2&25 mounted upon rods 26-27 extending to the outside of the furnace, as shown in Fig. The smoke and gases then pass through a lateral opening 2S into the space between the outer covering 29 of the furnace and the furnace proper, as shown in Fig. 2. That portion of such outer space into which the smoke is conducted is inclosed by vertical plates :SO-3l which are arranged forward of the openings 32 at opposite sides of the door, which plates extend from the upper portion ot' the furnace to a point substantially on a level with the upper portion of the water jacket 8. The smoke and gases pass down around the lower ends ot such plates 30-31, and then rise and pass through the openings 32 in the top plate 33 to the smoke pipe 23. I prefer to make the plates 80-31 of the length described, but obviously they may be of any desired length.
Although my furnace is primarily adapted for heating water for steam-heating, it may also be adapted for heating water for hotwater heating, and therefore I wish it to be understood that my improvements may be used in any furnace to which they are adapted.
An important advantage arises from shap ing the flues as described, which is that the furnace is thereby made practically self-clear ing since all portions of the flues are exposed to the flame, and therefore the soot is pre vented from gathering upon them.
That which I claim as my invention, and desire to secure by Letters Patent, is-
I. 1n afurnace, the combination with a lireboX, of dues extending through said fire-box, said tlues being pearshaped, the rounded portions being lowermost, substantially as described.
2. In a furnace, the combination with a lirebox, of a plurality of layers of fines extending through said treabox, said ues being substantially pear-shaped in cross section the rounded portions being lowerinost and the ues in the different layers being staggered, substantially asdescribed.
3. A furnace fiue consisting of a tube substantially pear-shaped in cross section, the rounded portions being lowermost substantially as described.
4. In a furnace, the combination with a tireboX, and an outer casing, of a steam dome, a smoke box, passages alording communication between the tire-box andthe smoke box, means tor closingr said passages, vertical plates 30--3l, a passage alording communication between the space inclosed by said plates and the upper portion of the {ire-box, and one or more Openings 32, substantially as described.
