KENNEDY PARK, OF oAMenInen, MASSACHUSETTS.
STEAM-GENERATOR SPECIFICATION-forming part of Letters Patent No. 627,521, dated June 27, 1899.
Application filed January 4, 1899. i
tors, of which thefollowingis a specification.
This invention relates tosteam boilers and generators of tubular construction, a plurahty of tubes being arranged overthe fire-' box and connected at their ends with head-,
ers which communicate 'with' the amma Water drums.
The invention has for its object to provide a steam-generator of this type which shall be of compact construction, the tubes being of such length asto enable theapparatus to be conveniently usedon steam-yachts and other relatively small navigable vessels, the gen erator beingat the same time constructed so as to utilize as fully as possible the efficiency of the fire.
The invention consists in the improvements which I will now proceed. to describe and claim. 1
Of the accompanying drawings, forming a part of this specification, Figure l represents a front elevation of a steam-generator embodying my invention, a part of the casing being removed. Fig. 2' represents a section on line 2 2 of Fig. 1. Fig. 3represents a section on line 3 3 of Fig.2.
The same letters of referen ce indicate the same parts in all the figures. v
I have shown my invention embodied in a steam-generatorhaving two fire-boxes, each having a grate a and'a fire-door a.
12 represents thebridge-wall, which forms the rear end of each fire-box.
c c c 0 represent inclined tubes located above the fire-boxes, the forward portions of said tubes-bein g separated by spaces, through which the products of combustion from the fire-boxes pass upwardly to the chamber or space 01 above said tubes. A vertical wall or baffle-plate'e extends from the top of the bridge-wall across the series of tubes and to the space or chamber d, where said wall terminates, the wall forming a barrier between the space over the fire-boxes surrounding the front portions of the tubes 0 and a corresponding, although preferably shorter, space surrounding the rear portions of the tubes Serial No. 701,113. (No model.)
and extending from the rear portion of the chamber 61 downwardly to a space or chamber 61 below the rear portions of the tubes and behind the bridge-wall b. The front and rear ends of the tubes 0 c are inserted in front headers f and rear headers f, the headers f collectively forming a front Wall and the headers f a rear wall. The upper ends of the headers f are connected by tubes f with the steam-drum 9, while the upper ends of the headers f are connected by tubes f with said steam-drum, the tubes f entering the drum 9 at a higher level than the tubes f so that the steam and hotwater, which are caused by the inclination of the tubes 0 c to flow upwardly into the headers f, pass from thence into the steam-drum at or above the water-level of the latter, while the water from the lower portion 'of the steam-drum flows downwardly through the tubes f into the headers f and into the lower ends of the tubes 0 c.
It represents a water-drum located below and connected with the lower ends of the 'heade1's-'f,'said drum being connected by ber d,'an inclined baffle-plate e, forming an extension of the wall 6, causing the products to pass into the forward portion of said chamber d, as indicated by arrows in Fig. 2. The products of combustion pass through the chamber at, over the baffle-plate 6, across the upper end of the wall a, and then pass downwardly between the rear portions of the tubes 0 and c to the chamber 61'. The end portions of the space or chamber 61 communicate with vertical fiues or uptakes 2' 4), Fig. 3, which are formed by vertical walls or partitions jj, located between the rear portions of the tubes 0 c and the end portions j of the external casing. The said flues 2' extend from the chamber d to the endsof a supplemental chamber m, formed by a casing m, located above the series of tubes at the rear. side of the steam-drum, as shown in Fig. 2. v Theescape flue or stack 0 extends from the upper portion of the chamber m, and in said chamber is located a feed-water heater composed of a connected series of tubes 1), having suitable connections at one end with a source of water-supply and at the other end with the steam-drum g. To aiford space for the vertical fines it, two headers f are omitted from the ends of the series of rear headers, and the tubes 0 c that would have entered the omitted headers f are connected with the vertical tubes t' which are located beside the tube 2', and thus take the place of the omitted headers f.
It will be seen that the described construction causes the products of combustion after passing upwardly between the forward portions of the tubes 0 c to pass downwardly between the rear portions of said tubes and then pass through the feed-water heater before escaping, the entire arrangement being such that economy of space and an economical use of the fuel are obtained. This generator is well adapted for use on sea-going vessels of small size, such as steam-yachts, owing to its compact form.
It is obvious that the arrangement may be such that the products of combustion will pass downwardly through the flues t' 2' from the chamber 01 to the chamber d and then upwardly between the rear portions of the tubes c c to the chamber m and through the feedwater heater. I do not consider the last-mentioned arrangement, however, so desirable as that first described, it being obviously more advantageous to pass the products of combustion directly from the chamber (1 downwardly between the rear portions of the tubes 0 and c and then upwardly to the feed-water heater.
The vertical tubes i which take the places of the omitted headers f, serve also to support the steam-drum, and as the tubes '11 extend from the lowest portion of the steam-drum and are connected by the tubes "6 with the water-drum a flow of water from the steamdrum to the water-drum is insured so long as any water remains in the steam-drum.
The tubes 1" are connected with the steamdrum by means of flanges 2' formed 011 the tubes 1'', and bolts '6 passing through said flanges into the steam-drum. To insure a tight joint, the sleeve or nipple i is expanded in the orifice formed in the steam-drum to connect it with the tube 2", said orifice being smaller than the interior of said tube. The sleeve 2' extends into the tube t" and is expanded against the inner surface of the latter, the tube being preferably provided with an internally projecting annular seat against which the outer portion of the sleeve 11 is expanded. This connection may be applied to other parts of the apparatusf0r example, where the headers f join the waterdrum h.
The wall or partition e may be formed by inserting suitablyshaped sections of firebrick between the tubes 0 c c c, or said wall may be hollow and formed as a water-leg, its interior communicating with the said tubes,
in which case the wall may be composed of a series of headers like the headersf orf, and the tubes instead of extending continuously across the bridge-wall would each be made in two parts or sections expanded into the headers forming the wall 6. The walls or partitions jj may also be made by inserting sections of fire-brick between the outer vertical rows of tubes at the rear of the wall e.
I claim- 1. A boiler or steam-generator comprising a fire-box, a series of tubes extending lengthwise over the fire-box and across the bridgewall of the fire-box, a partition extending across the series of tubes between their forward and rear portions and extending partly over the forward portions of the tubes, said partition causing the products of combustion rising directly from the fire-box to pass be- ,tween the forward portions of the tubes including their forward ends, an elevated space or chamber above the tubes to receive the products of combustion from between the forward portions of the tubes, a lower space or chamber below the rear portions of the tubes, an escape fine or stack, and connections between the stack, the lower chamber, and the elevated chamber, whereby the products of combustion received by the elevated chamber are conducted first downwardly and then upwardly, the said products being presented to the rear portions of the tubes in their passage from the elevated chamber to the stack.
