STEAM-BOILER.
Specification of Letters Patent.
Patented Feb. 6, 1906.
Application filed July 18, 1905. Serial No. 279,215.
To all) volume it nuty concern:
Be it known that I, PAUL h'lEURISSE, a citizen oi France, residing at 4 Rue des Meuniers, Lille, France, have invented new and useful Improvements in Steam- Boilers, of which the following is a specification.
This invention relates to a steam-boiler occupying a very small space, considering its root evapcrative power, and characterized by its particular construction, which consists of an upper tubular transversal body a cluster of lire-tubes arranged in this tubular body; a vertical layer of water and an almost horizontal layer of water, both connected with the tubular body and making between them an angle of less than ninety degrees; a cluster or nest of vaporizing or water tubes joining the two layers of water; a grate formed by water-circulating tubes connecting the vertical layer of water to a transverse collector and by fire-bars interposed between these tubes, and a group of vertical tubes forming a water-wall and connecting the transverse collector with the horizontal layer of water.
In the annexed drawings Figure 1 is a vertical longitudinal section at the boiler. Fig. 2 is a front view of the furnace. Fig. 3 is a transverse section. Fi s. 4 and 5 are sootional detail views, to en arged scale, showing the connection of the boiler-tubes. Fig. 6 is an elevation of a portion of a bar of the grate. Fig. 7 is a plan of this bar. Fig. 8 is a transverse section.
The boiler is composed of an upper transverse body or drum a, having two opposite flat ortions b c, forming tube-plates, slightly inclined to the horizontal to prevent sediment from settling on the lower plate. In these lates are ex anded fire'tubes d, arrange in quincunx orin. This upper transverse body (1 forms a reservoir of water and steam and joins two headers cf, one, 6, a vertical header leading from the lower part of the drum and serving to return the water ,the other, f, discharging almost on the horizontal axis of the body and serving to receive the steam. The axis of this latter header is slightly inclined to the horizontal and forms, with the axis of the vertical header, an angle less than ninety degrees.
The headers are united by a nest or cluster of vaporizing-tubes composed of water-tubes 9, having the form of the arc of a circle whose center is at the oint of intersection of the axes of the hea ers. The tubes 9 are arranged in quincunx form and are mounted in such a manner as to be easily removable and accessible, as shown in Figs. 3 and 4. On the side of the vertical header these tubes have an opening made in the lower face of the tube to insure the circulation of the water in the tubes, while preventing the deposit of sedi ment in the same. On the side of the other header the tubes g have holes throughout their circumference.
The vertical header is extended beneath the boiler, and from the foot is led a series of tubes it, connected with a transverse collector or box i. Two or more rows of vertical tuhes arranged. in quincunx lorni, connect the collector i, with the horizontal header, serving to collect the steam.
The tubes h are disposed at such a distance apart as to enable to be fitted therein firehars of special construction. (Shown more clearly in Figs. 5, 6, and 7'.) The combination of the tubes 7?. with these bars forms the boilerrate.
TheTeeding and removal of the water from the boiler takes place in the lowest zone of the layer of return-water, in which the deposit of the sediment also takes place.
Continued circulation of the ases is insured by baffles l m n, the bafile Tbeing constituted by gratings placed between the tubes 9 of the lower row of the tubular nest. The steam-outlet is through the tube 0, and the exit of the gases takes place through the chimney p.
The boiler is completed by a sheet-iron casing, in which is loft in the lower part an opening 1" for charging the fuel. This casing is also provided with doors .9 for the inspection of the tubes g.
The arrangement just indicated affords a large combustion-chamber notwithstanding the small height of the apparatus. The gases rise from the grate, licking the lower part of the uoup of water-tubes, and also the vertical to es 1, forming a water-wall, descend again around the tubes g in order to pass finally through the fire-tubes d of the upper part candissue to the chimney. There is thus a very long passage for the gases, which is favorable to the economical utilization of the heat. This passage is indicated by arrows in the drawings.
The circulation of the water in the boiler is also indicated by arrows in the annexed drawings. This circulation, which is very active, prevents the sediment from settling in the tubes g. This sediment settles in the lower part of the vertical header e, from which it is eas to extract it. The scale, on the other han settles in the tubes h and j, which are the most heated and which can be easily cleaned on account of their position and because they are straight.
The water in the water-tubes vaporizes by the transmission of heat, carrying with it a certain quantity of water, and this mixture, discharging into the steam-collector, passes into the upper body, where the separation of the steam occurs This steam, being besides obliged to lick the upper part of the smoketubes, is sli htly superheated before leaving the boiler by reason of the double course which it is obliged to make around the liretubes.
I claim 1. A steam-boiler comprising an upper transverse tubular body a situated in the path of the products of combustion in combination with a vertical header 6 communicating with the said tubular body, a header, substantially horizontal, communicating with said tubular body, and a cluster of watertubes 9 connecting the two headers, and substantially concentric with the tubular body a, substantially as described and for the purpose specified.
2. A steam-boiler comprising an upper transverse tubular body a situated in the path of the products of combustion and hav- 1n two opposite flat portions 1), c, forming tu e-plates slightly inclined to the horizontal, in which are expanded fire-tubes d, in combination with a vertical header 6 communicatin with the said tubular body, a substantia y horizontal header f discharging into said tubular body, and a nest of watertubes 9 connecting the two headers substantially concentric with the tubular body a, substantially as described and for the purpose specified.
3. A steam-boiler comprising an up er transverse tubular body a, havin two at portions 1), c, forming tube-plates s ightly inclined to the horizontal, in which are expanded fire-tubes d, in combination with a vertical header 6 communicating with said tubular body; a header, substantially horizontal, 5o communicating with said tubular body; a nest of water-tubes 9 connecting the two headers, and substantially concentric with the tubular body; water-circulatin tubes It connected at one end to the vertica layer of water; a transverse collector i, into which the other ends of the tubes h discharge; said tubes It being situated in proximity to the grate; and a group ol vertical tubes formmg a water-wall, and connecting the trans 6o verse collector t with. the horizontal header, substantially as described and for the purpose specified.
