ETIENNE LAGOSSE AND JEAN BOUGHE, OF PARIS, FRANCE.
MULTITUBULAR STEAM-BOILER.
SLECIFECATION forming part of Letters Patent No. 337,506, dated March 9, 1886.
Application filed December 4, 1885. Serial No. 184,732. (No model.)
To aZZ whom it may concern.-
Be it known that we, ETIENNE LAGOSSE France, residing at Paris, in said Republic, have invented anewand useful Improvement in Multitubular SteanrBoilers, of which the following is a specification.
A boiler constructed according to our invention is especially characterized by the combination of the following essential qualities:
First. The system of circulation of the water and of the steam is 1-ational thatis to say, that the water and steam circulate always in the same direction-whichpermits of a rapid circulation, owing to which the caloric of the furnace is well utilized. Moreover, the direction of the movement of the fluid mixture is contrary to that of the movement of the products of combustion and gives thus a methodical heating.
Second. The course followed by the steam .at the exit of the tubes has the least length which is possible for it to arrive at the steamchamber. Its direction approximates to the vertical, and the conduits through which it passes in its course present no choking nor any abrupt changes of direction, conditions which much facilitate the upward passage of the steam, and consequently the production of the latter. a
jThird. The steam-generating surface has a 5; very considerable development, which permits alarge vaporization.
The invention consists in combinations hereinafter described and claimed, and illustrated in the accompanying dra\ vings,-which represent a boiler constructed according to our invention.
Figure 1 is a front elevation of the steamboiler. 'Fig. 2 is a longitudinalvertical sec-, tion. Fig. 3 is a back view. Fig. 4 is a ,nearly vertical section parallel with Fig. 2
a face view illustrating the communication between the elements of the teed-water heater.
Similar letters of reference designate corre sponding parts in all the figures.
The boiler is composed, essentially, of the following principal'organs: A cylindric receiver, I, of water and steam, constituting the upper part of the boiler, placed horizontally and longitudinally and outside of the flues through which pass the products of combustion, which permits, in case of repair, its being dismounted without detaching the ma sonry of thefiues. Two or more steam-collectors, J J, placed horizontally and transversely in front, the upper one forming part of the cylindric receiver 1. They communicate with each other by means of vertical tubes K K, of large section and easy of removal. The boiler, as will be further sbown,will thus be divided in as many groups of tubes as there are collectors J J. i This division has for its object the augmentation of the surface of vaporization, and to facilitate from a given amount of surface avery great disengagement of steam. The feed-water collectors L L, in numberequal to that of the collectors of steam placed atthe rear of the boiler horizontally and transversely,and indirect communication with the rear and lowest part of the cylindric receiver I by means of large vertical tubes M,
easily removable, generating elements of which.
communication at their-two extremities by means of connectingboxes O of cast-iron, castvsteel, or other-convenient metal, of a special form, which permits the obtaining of vertical faces in front and in rear of the boiler notwithstanding the great slant of the tubes, which facilitates the rapid circulation of the water and steam. The exterior form of the extremities of the tubes is slightly conical, (see Fig.
-;4,) and the inlet-openings of the boxes 0 receive the ends of these tubes, which are forcibly inserted therein, the parts which penetrate the interior of the boxes being expanded in such manner as to form alittle annular-collar, P, Fig. 4, which gives great stability and an absolutely steam-tight joint.
Besides the connectingboxes 0 serving to connect together the tubes of one generating element, other boxes of communication, Q, serve to connect the elements together.
The joints between the connecting-boxes O and the boxes of communicationQ are obtained by means of little tubes B, Fig. 4, of which the diameter is at least equal to that of the tubes N Nof the elements. This construction has the advantage of preventing any choking of the passages, which might interfere with the circulation of water and steam.
The absence of any choking of the conduits is one of the points which characterizes our boiler. WVe may here mention that we do not pretend to claim, broadly, the combination of tubes with connecting'boxes and boxes of communication; but we consider as making part of the new combination which constitutes our invention the arrangement of the tubes N N of one element at ditierent levels, which permits us to give our connecting-boxes Oan inclined position, approaching to the vertical, to avoid the abrupt changes of direction in the passage of the steam after it has left the tubes. This essential difi'erence cannot be realized with horizontal connecting-boxes. Each joint is kept tight by two or four bolts, a a, Fig. 5, which assures absolute security. The heads of these bolts are received in grooves b I), made in the thickness of the box 0, and represented in Figs.'4, 5, and 6.
As has been already said, we make use in one boiler of two or more steam-collectors, J J, and as many feed-water collectors, L L, and we thus divide our boiler into groups of tubular elements separated by fire-brick-partitions A*. This is a point absolutely new, of which the object is to increase the section of disengagement of vapors, as will be hereinafter explained. The boiler represented contains-two of these groups, and as these groups are identical it will be sufficient for usto describe one-for example, the lower one. As may be seenin Fig. 1, the lower group is fed-at the lower part of its rear end by the feed-water collector L. The steam which escapes from these tubes arrives directly through the boxes Q and 0 into the lower steam-collector. J, by a number of orifices equal to that of the tubular elements which are found in one horizontal range. Now, as
these orifices, as has been above stated, have.
a section at least equal to those of the tubes. in order to avoid choking the section of disengagement of steam in the collector J is equal at least to one-quarter of the total section of the four horizontal ranges of the tubes of the lower group. The section of the two tubes K K, which connect the collectors J J, is-equal to that of all the tubes in one horizontal range. The upper group is fed by the water-collector L, and its steam is delivered in the collector J. As this groupie less heated than the lower one, it produces in proportion to its heating'surface less steam, and may contain a larger number of horizontal ranges. of tubes for a given surface of disengagement of steam. So in the example represented there are six horizontal ranges of tubes, and the section of disengagement of steam is one-sixth of the total section of the tubes. If, then, we take a mean between the sections of disengagement of the two groups, we have a'section of disengagement of vapor equal to about one-fifthof the section of all the tubes of the generator. (These proportions are not absolutely necessary to be observed.) Yet such proportions have not been arrived at in multitubular boilers heretofore constructed, and this result is due to our di vision of the boiler into distinct groups 0t."
tubular elements, which we claim.
We pass now to our system of feed-water heater. In the example represented it is placed on one side of the genera qr; but it may be understood that it might be might be divided or placed one-half on each side, according to circumstances. In case of ehind it, or it a marine boiler it might be arranged above ICO such manner as to be tightened by internal pressure. At the front of the furnace the tubes of each of these elements simply pass through a metallic plate, Y, which may, if necessary, havea flange to facilitate its being supported upon that one below it, and the box of communication T connects the elements together horizontally by means of the conical joints,
which fit directly upon the extremities of the tubes, being maintained in place by bolts.
Arched boxes serve to connect together the different horizontal ranges.
These are arch ed to permit the tubes to come as close together I as possible, as may be seen in Fig. 1.
W'e may here remark that it is easy by isolating a certain number of tubes of the upper part of the feed-water heater to form of them a superheater or steam-drier by putting them in communication with the upper part of the steam-chamber I.
This boiler may have a furnace of any known or suitable construction, and is to be enveloped in a casing of brick-work or metal, like those common to the ordinary multitubular boilers.
What we. claim as our invention, and desire to secure by Letters Patent, is-- 1. The combination, in a multitubular boiler, "of groups of tubes arranged one above another, and an interposed partition, A*, each group consisting of several horizontal ranges of tubular e1ements,N N O 0, boxes QQ, connecting the elements of one range with those of 5 the range above, a transversely-arranged water-collector, L L, at the bottom of one end of the group, and atransversely-arranged steamcollector, J or J, at the top of the other end of the group, all substantially as herein described.
2. The combination, with the superposed ranges of tubesN N, of the obliquely-arranged connection-boxes O O, and obliquely-arranged communication-boxes Q Q, whereby the circu- I 5 lation of the steam and water through said boxes is sinuous, but nearly vertical, substan-' tially as herein described.
3. The feed-water heater consisting of the combination of tubes V, connecting boxes S, having openings opposite said tubes fitted 20 with conical plugs U, connecting boxes'l, and plates Y, all substantially as herein described.
In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
