PETER PENTZEN, OF NEWPORT, RHODE ISLAND, AND CHRISTIAN FRED- ERIK OLSEN, OF ATTLEBOROUGII, MASSACHUSETTS.
TUBULOUS BOILER.
SPECIFICATION forming part of Letters Patent No. 541,829, dated July 2, 1895.
Application led September 28, 1894. Serial No. 524,413. (No model.)
Fo @ZZ whom it may concern.-
Be it known that we, PETER BENTZEN, residing at Newport, in the county of Newport and State of Rhode Island, and CHRISTIAN FREDERIK OLSEN, residing at Attleborough, in the county of Bristol and State of Massa cbusetts, subjects of the King of Denmark, have invented certain new and useful Improvements in Tubulous Boilers, of which the following is a specification.
Our invention relates more particularly to that class of generators known as tubulous boilers, and in which a steam receptacle and separator and a water vessel are connected by tubes in which the steam is generated; the objects of our invention being', first, to so construct the said generator and its par-ts connected.
that it shall be extremely simple and inexpensive; second, to provide an enlarged furnace or grate area by special arrangement of parts; third, to render it possible to readily detach a generator tube; fourth, to render it possible to readily detach from the steam separator or receptacle and water vessel a complete sect-ion of tubes without molesting `the remaining tubes; fifth, to so arrange all parts that ready access may be had to the same for purposes of repair, tbc., and sixth, to connect the generator tubes to manifolds, which communicate each with the water vessel,to provide a far larger escape area for the steam than the area of the inlet Water. \Vith these objects in View, reference is had to the annexed drawings, and to thespecitication, in which- Figure l is a vertical front section of the improved generator taken on the line l l of Fig. 2, and illustrating the arrangement of a section of generator tubes and the relation of parts. Fig. 2 is a side elevation of Fig. l, with the outer casing removed, and a number of sections ofthe generator tubes of Fig. l displaced. Fig. 3 is a perspective view of a corrugated separator plate to be placed within the steam separator. Fig. e is an enlarged elevation view of a manifold, showing the manner of tube connections, as set forth in Fig. l. Fig. 5 is a top View of a position of the water vessel showing the relative portion of the outlet with which the manifolds are Fig. 6 is an enlarged .view of a union joint. Fig. 7 is an enlarged vertical sectional view of the water vessel taken on the line 2 2 of Fig. 2. Fig. 8 is an enlarged View of a portion of the steam pipe detached.
Similarletters refertosimilarpartsthrough out the specification and drawings, in which-- A represents a steam receptacle and separator, and` B a water vessel and mud drum. This water vessel is preferably made cylin drical in form internally, bntwith a flattened longitudinal top b as in Figs. l, 2, 5 and 7. Rising from the flat top bare threaded tubular projections C, which are arranged in al ternate rows with relation to each other along` the said top b, and provided with openings communicating with theinteriorof the water vessel B. This water vessel B is preferably made of malleable iron or steel, and when the generators are made in large sizes the water vessel may be made of several parts, securely fasten ed or screwed together. A door or head D is placed at each end and securely seals the openings of the said water vessel. The separator is preferably formed of steel and is provided with aremovable head E, which permits access to the interior of lthe said separator or steam receptacle; and at a certain position of, and preferably directly underneath, the separator, one or two pipes F connect the said separator A with the water vessel B. The pipe F is preferablyplaced near one end of the said separator or receptacle, as shown in Fig. 2.
`To each projection C is secured a manifold G (see Fig. 4) which is connected at its lower end g by means of a short tube N and a union joint I-I, which latter is shown in enj larged form in Fig. G. The manifolds Gr by means of being connected to said projections are thus arranged in alternate rows and, at alternate heights, as shown at H Figs. 1 and 2. These manifolds are preferably provided with ve tubular projections I, which are adapted to receive the expanded lower ends of the generator tubes J, which in Fig. 4 are shown partly broken. If it is desired, of course the said manifolds may be formed to receive a greater number of generator tubes than the number here shown. Opposite the end of each generator tube J as described, is formed a ,hole opening into the interior aper- IOO ture of the manifold G and adapted to receive a plug K to close the said opening. These openings and plugs K correspond in number to the numberof generator tubes J entering a manifold, and with the latter comprise what will hereinafter be termed a section. The object of the said construction is that by removing any one of the plugs K the e-nd of the corresponding generator tube J is thereby exposed, and readily gotten at, for the purpose of expanding it within the projection I, or to assist in removing the said tube. Into the lower end g of each manifold is preferably screwed or expanded a tube N, which tube connects the manifold, by means of a flange rt and a union nut H, with the water vessel B, by the said nut screwing on to the outwardly threaded projections C. By means vof this construction it will be readily seen that,if the union joint is discennecteda complete set or section of tubes are thus. released at their lower ends, and can then be readily detached from the separator A.` at their upperends, for purposes of repairdrc. tubes, in connecting with the upper part of the said separator, pass from the said manifold in series of tive almost horizontally above and across the fire grates, and, by means of a bend at O of preferably a large radius, passabout vertically until bent again similarly at P, thence almost horizontally over the start'- ing placcuntil gradually curved downwardly at Q, to be connected by means of expansion. within and with the separator A, at q.
The advantage over other forms ot' generators of connecting the `generator tubes tol vertical manifolds which are arranged in rows longitudinal with the water vessel B, and the separator, centrally and between the said separator and Water vessel, is that the lower portions of the said tubesat their places of connection with'the said manifolds, are raised a considerable distance above the tire grates,
thereby utilizing and economizing space and greatly adding to the furnace area. One of the essential features of thisconstruction is that it provides a greater escape area for the steam in proportion to the inlet area for water than other forms of steam generators. The steam will in consequence thereof [ind a more even and easy escape. Besides this ad vantage the manner in which the tubes are 4connected and the easy bends and shapes which they are thus enabled to assume reduces their cost both in manufacture and re pair. It is also seen that a large heating surface is thereby presented to the furnace flames and gases, and a. quicker generation of steam is the consequentJ result.
The aforesaid manifolds are made of steel or other suitable material able to withstand the subjected heat and pressure.
In larger generators of course the number of tubesiand of sections of tubes may be increased, proportional to the working pressure and volume of steam required for service.
Vithin the radius formed by the bend of The said injector, which are not shown. :parallel lengths of thc feed heater pipe and iits many folds furnish a grate surface arca lfor the action of the heat for heatingthe injected water, which ordinarily passes through the said pipes before it reaches the separator `iA, and finally, the water vessel B. rangement: can of course be varied,but the siarrangement as set forth is considered the most satisfactory..
-its sidestoward the steam feed pipe V.
the innermost of the tubes J, between the said tubes and the separator or receptacle A, along each side of the latter is formed a hollow space R, R, and within these spaces are arranged parallel feed water heater pipes R', R', which `run the length of the separator or steam receptacle and are connected together at their ends as shown at r. The said pipes on each side of the said separator or receptacle connect as at r', by means of a cross pipe. The said pipes are preferably arranged in layers, as shown, and one end thereof is connected with the separator A, as at r2. The other end thereof, as at the valve S passes outside of the boiler casing and is adapted to connect with an injector or water supply pipe. From a val-ve T, extending downwardly within the separator, is preferably arranged a short pipe 8, and connected with this valve T is a pipeleading from the outside of the boiler ator casing and connect with a feed pump or The many This arrepresents a feed valve located, as stated,
tacle A and intended to connect with a donkey pump as a mattei'. of safety for water supply. Within the separator or steam receptacle A is placed a separator plate U provided with lateral corrugationsu. This plateU extends almost the entire length of the separator A, and is arched into a sen'iicircular form as show-n ifn Fig. l. (See-also dotted lines, Fig. 2, and detached perspective view, Fig. 3.) The office of the plate U is that when the moisture ladened steam issues from the gen crater tubes J, against the said plate, the said moisture and condensed water will be separated from the dry steam as it comes into contact with the surface of the said plate, as the moisture will thereby adhere to it while the steam passes onaround over its ends and tip-under The corrugations u are formed in the plate U so thata greater surface will be presented to the issuing steam, andthe water will more readily drain off from its surface, running thence back into the water vessel B, through the pipe F.
The steam pipe V as shown in Fig. 2, is provided with an ordinary regulator valve t* and is secured to and enters the separator A and then passes parallel with and under the separator plate U, and is provided with an opening or slot forits entire length, undersaid plate, along its upper portion, the parallel edges thus formed being preferably turned IIO backward, as shown in Fig. l, 'and in Fig. 8, enlarged View.
The lower part of the seperator A is covered with a protecting material W to preserve the metal from the injurious action of the flames; and the outer sides of the tire boxes are walled with or formed of suitable fire bricks,orothernonconductingmaterial. The necessary draft orotherself-closing'doors are provided as shown at X, X, and Y, Y for the fire box and for the ash receptacle. A jacket Z is placed over the whole, and the funnel Z is continued therefrom. A lining of fire brick Z2 is also placed along each side of the water vessel B to protect the same. It is obvious that this form of steam generator containing no waste spaces, can be made relatively smaller in size than generators heretofore constructed, at the same time providing a larger heating surface and lire box area in proportion to such full size than others have provided. As previousl \7 set forth its parts can be readily gotten at for replacement and repair, and on account of their simplicity 4are cheap in construction, while the steam escape area is large and free. In cases where agenerator of this construction is used in steam ships in which the coal bunkers are placed at the sides of said generator, the walls of the said coalbnnkers located adjacent to the said generator can be made in parts so that they can be easily removed, to make room for the removal of any number of tubes, or sections thereof with their respective manifolds.
