STE AM-B OILER.
Specification of Letters Patent.
Patented April 13, 1909.
Application filed July 6, 1908. Serial No. 442,123.
To all whom it may concern:
Be it known that I, PIERRE BARNES, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Steam-Boilers, of which the following is a specification.
The object of this invention is the provision of a water-tube boiler having an improved system of piping whereby the water circulation therein is facilitated and the generation of steam effected in a rapid and economical manner.
The invention consists in the employment of series of inclined steam generating tubes communicating at their opposite ends with headers which are connected with waterdrums so as to afford a plurality of comparatively direct water circuits through such elements, and from these several assemblages of tubes and headers are individual draw-off tubes for conveying the generated steam into the receptacles which are provided therefor.
In the following description of the invention, reference is had to the accompanying drawings, wherein,
Figure 1 is a vertical section of a steam boiler embodying the invention; and Fig. 2 is a cross sectional view of portions of the same.
The numerals 5 and 6 represent water drums or transverse pipes respectively disposed at the front and rear of the boiler; and 7 and 8, steam drums which are similarly disposed at a higher elevation and, desirably, in corresponding transverse planes. These drums may be connected by pipes with a common steam receptacle or they may bev piped with a superheater, of ordinary type; but as such devices are foreign to the present invention, they are not illustrated in the drawings.
Respectively connected by short tubes 9 with the water-drums 5 and 6 are primary headers 10 and 11; and similarly connected by longer tubes 12 are secondary headers 13 and 14. These secondary headers are respectively connected by tubes 15 with the adjacent steam drum. Connecting the primary headers at the front with the secondary headers at the rear are series of inclined tubes 16; while series of inclined tubes 17 fulfil the same office with respect to the primary headers at the rear with the secondary ones at the front. The various aforesaid headers are arranged so that the alternate series of tubes, 16 and 17, incline in opposite directions, and the header connecting tubes 9 and 12 alternate in the respective water-drums.
The operation of the invention is as follows: The water being principally heated in the inclined tubes 16 and 17 is caused to ascend therethrough into the secondary headers lt and 13 wherein the steam which was generated in the inclined tubes is liberated and escapes through the tubes 15 into the steam receptacles 8 and 7. The water after being freed of the produced steam is displaced by following currents and caused to flow from the secondary headers in clownward courses through the tubes 12 and into the water-drums 5 and 6, whence it is returned upwardly through the tubes 9 and into the primary headers 10 and 11 to replace the water being withdrawn through the inclined tubes, as aforesaid, and thus complete the scheme of circulation.
As will be obvious from the water outflow tubes of the secondary headers being disposed in alternate relation with the inflow tubes of the primary headers, the various return currents thus established are rendered comparatively short and direct and, so far as the inventor is aware, there has hitherto been no such effective provision for the proper circulation of the water in a steam generator of the water-tube type.
What I claim, is-
1. In a steam boiler, the combination, with series of inclined water tubes, of separate headers connected to the opposite ends of each of said series of tubes and arranged at diiferent elevations, awater drum and a separate steam drum, the former being arranged below and connected to both the upper and the lower headers, while the latter is arranged above and connected only to the upper headers.
2. In a steam boiler, the combination, with alternate series of oppositely inclined water tubes, of separate headers connected to the opposite ends of each of said series of tubes and arranged at different elevations, a water drum and a separate steam drum, the former being arranged below and connected to both the upper and the lower headers, while the latter is arranged above and connected only to the upper headers.
rate Water drums and steam drums, theformer being arranged below and connected to both the upper and the lower headers,
] While the latter are arranged above and connected only to the upper headers.
In testimony whereof, I alfix my signature in the presence of two Witnesses.
PIERRE BARNES,
