JAMES C. STEAD, OF BROOKLYN, NEW YORK.
STEAM-BOILER.
SPECIFICATION forming part of Letters Patent No. 750.721, dated January 26, 1904.
Application filed September 23, 1902. Serial No. 124,599. (No model.)
To all/l w/wm, it nuty concern.-
Beit known that I, J AMES 0. STEAD, a citizen of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, State of New York, have invented certain new and useful Improvements in Steam-Boilers, of which the following is a specification accompanied by drawings.
My invention relates to steam-boilers; and its objects are to improve upon the construction of such boilers and increase their efficiency with improved and more rapid circulation and reduce the liability of the walls of the furnace from burning out.
Further objects of my invention will hereinafter appear; and to these ends my invention consists in a steam-boiler for carrying out the above objects constructed and arranged and having the general mode of operation substantially as hereinafter fully described in this specification and shown in the accompanying drawings, in which- Figure 1 is a longitudinal sectional elevation of aboiler embodying my invention. Fig. 2 is a front elevation of the same, partly in section. Fig. 3 is a side elevation, partly in longitudinal section, of a modified form of boiler embodying my invention. Fig. 4 is a partial front elevation, "partly in section, of the form of boiler shown in Fig. 3, showing the header connections. Fig. 5 is a detail plan view, partly broken away, showing the connection between the mud-drum and separator in the boiler illustrated in Fig. 3; and Fig. 6 is a detail plan view, partly broken away, showing a modified form of connections between the mud-drum and steam-separator.
Referring to the drawings, and more particularly to Fig. 1, a water-tube boiler is shown in which the water is kept in constant circulation from the bottom to the top by a suitable system of piping, headers, and in this instance a separator. According to the construction shown the forward bridge-wall A is arranged at the rear of the grate B and may support a suitable upright partition or baflieplate O. The rear bridge-wall D is shown as supporting the bottom header E, which, according to the construction to be described, also constitutes a mud-drum.
A separator F is suitably supported in the upper portion of the furnace and connected by piping G with the bottom header E. The pipes or water-tubes H all connect with the bottom header or mud-drum E at the front of the same and extend into the separator after having passed through the fire-space. A downwardly-extending partition or bafHe-plate I may be supported from the top of the boiler, and the circulation of heated gases then passes upwardly in front of the partition O, downwardly over the top of the same between the partitions I and O, and beneath the partition 1, taking an upward direction again before passing out through the flue.
A steam-dome J is placed, as shown, in
communication with the steam-separator F. The pipes H extend back and forth from the lowermost pipe upwardly to the steam-separator F, each pipe extending in an upward direction and the ends of the pipes being suitably connected by the headers K. The uppermost pipes H extend into the steam-separator and curve upwardly, as shown, above the water-line of the separator. This construction is made use of in connection with all the circulating-pipes which extend into the separator.
Coils of pipes L are arranged adjacent the back wall O and are connected between the feed-pipe P and the steam-separator, these circulating-pipes L preventing the burning out of the rear wall. Side coils of pipes Q are also connected with the feed-pipe P and arranged on each side of the grate for preventing the side walls from burning out. These side coils Q are also in communication with the steam-separator F, as shown. Coils of water-pipes R are also arranged Within the fire-door and above the fire-box for further aiding in the efficiency of the boiler, these pipes R being also in communication with the feed-pipe P and connected to the piping leading to the separator F.
The feed-pipe P is shown in communication by a suitable connection S with the bottom header or drum E, and a draw-off pipe T is provided for drawing off the water.
According to my invention substantially horizontally arranged baffie-plates V are arranged between the rows of pipes or watertubes H and staggered relatively to each other to cause the heat to reach all the pipes, the directions of the circulation of the gases being indicated roughly by the arrows X. (Shown in Fig. 2.) The water passes down at the bottom of the separator F into the bottom of the header or mud-drum E, then through the lowermost row of pipes or water-tubes H, and is led backward and forward through the pipes H, each pipe being inclined up until the separator is reached above the water-line. The upward feed is also provided for the auxiliary coils L, Q, and R. i
The construction of boiler shown in Fig. 3 is useful for many purposes, but is adapted for a marine boiler. In this construction the forward bridge-wall a may be provided, as shown, with an upright partition or baflieplate 0, and the bottom header or mud-drum e is arranged at the rear of the boiler and in communication with the separator f, which in turn communicates with the steam-drum j. The piping 6, connecting the mud-drum e and the separator f, may be connected as shown in Figs. 3 and 5that is, from the end of the separator to the end of the drumor else this connectingpiping may be shifted in such manner that communication is made between the sides of the separator and mud-drum, respectively, as shown in Fig. 6, or between the tops of each. An upwardly-inclined plate 2. is preferably arranged extending from the forward bridge-wall a to the bottom header or drum 0, and the flame and gases in circulating from the grate 5 around the pipes of the boiler pass upwardly over the partition or baffle-plate 0 and from thence to the flue, taking finally an upward direction thereto.
The pipes or water-tubes it connect at their lower portions with the front of the bottom header or drum (1 and thence extend backward and forward, always inclined upwardly to the separator f, the ends of the pipes being connected by the headers to 1, 2, 3, 4, and 5. There may be any desired number of pipes and headers, I having shown a convenient number in order to illustrate my invention, and it will be seen that according to my invention provision is made for connecting a greater number of pipes to the headers as a greater height is reached in the boiler. As shown by way of illustration, the header 1 has provision for connecting three (3) tubes thereto. Headers Nos. 2 and at have provision for connecting four (4) tubes thereto. Header N0. 3 may have five (5) tubes connected to the same, and header No. 5 may have six (6) tubes connected thereto. According to this construction it will be seen that the tubes 7e extend upwardly in layers, the number of layers increasing with the height at which the layer is placed. This construction is provided in order to increase the circulation and efficiency of the boiler and has been found to operate efliciently and well for the purposes intended. A suitable feed-pipe u is connected with the muddrum 0 and provided with a suitable controlling-cock u, there being a circulation through the water-tubes from the bottom to the top of the boiler. Another feed-pipe a supplies water to the side coils 14 arranged on each side of the grate for protecting the side walls, and water is also supplied from the pipe 24 to the coils of water-pipes w, arranged above the firebox for protecting purposes, the coils a and 'w communicating with the steam-separator f.
Rear coils 0;, arranged adjacent the rear wall, are supplied from the feed-pipe u and communicate with coils beneath the top wall of the furnace, connection being made from thence to the steam-separatorf. The top plate y is shown between the front wall of the furnace-flue and the separator f, so that the gases must all pass oif at the rear of the flue.
As before, in the previous drawings baflieplatesc are shown arranged between the layers of pipes h, staggered relatively to each other to cause the heat to reach all of the pipes.
By the rapid circulation of the water through the circulating tubes and pipes the boiler is kept clean from scale, mud, or any sediment whatever and from burning out. All the mud and sediment will settle to the lower mud-drum, which will be blown out from day to day.
The steam is drier, for the water and steam come above the water-line, the water going to the boiler-level and the steam above the water-level, and in passing through the inclined tubes and pipes the circulation of the water carries all the water, scale, mud, and sediment with it and nothing can rest inside of the pipe until it gets to the separator. From there it falls to the mud-drum and is blown off.
Obviously some features of my invention may be used without others, and my invention may be embodied in widely varying forms.
Therefore, without limiting myself to the construction shown and described, nor enumerating equivalents, I claim, and desire to obtain by Letters Patent, the following:
1. In a steam-boiler, the combination of a bottom header, a separator parallel therewith and at the upper portion of the boiler, circulating-pipes leading from the header and arranged in layers each layer connected by a similar header and one layer above the other longitudinally of the boiler and at right angles to the separator, the upper layer of said pipes extending from the upper header and entering the separator on the side thereof and having their ends curved upwardly and terminating above the normal water-line therein.
2. In a steam-boiler, the combination of a bottom header, a separator parallel therewith and at the upper portion of the boiler, circulating-pipes leading from the header and arranged in layers each layer connected by a similar header, some of said layers inclining upwardly in one direction and others inclin ing upwardly in the opposite direction, the upper layer of said pipes extending from the upper header and entering the separator on the side thereof, and having their ends curved upwardly and terminating above the normal Water-line therein.
3. In a steam-boiler, the combination of circulating-pipes extending longitudinally backward and forward of the boiler and arranged in upwardly-inclined layers, the number of pipes per layer increasing With the height of the layer in the boiler, and means for circulating Water through said pipes from the bottom to the top, substantially as set forth.
4:. In asteam-boiler, the combination of circulating-pipes extending longitudinally back- JAMES C. STEAD.
