I Application filed March 5, 1909. Serial No. 481,484.
Toall it may concern:
Be it known that I, ALISON B.'S'1IRIJNG T a citizen of the United States, residing at Pleasant .Mount, in the county of Wayne and State of Pennsylvania, have invented certain new and useful Improvements in Superh.eating-Boilers, of which the followmg is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in boiler construction and more particularly to boilers of the Water-tube type.
One of the objects of the invention is to provide a boiler which will have a high heat- I g efliciency combined with ease of cleanmg. v
Another object is to provide a 'boiler of this type in which the circulating "Wvater shall have a definite circulation and whereby the coolest gases will always be directed against the tubes containing the coolest water. V
Another object thereof is to provide a new and improved superheater for a boiler ofthe above type.
, Other objects will be in part obvious and in part pointed out hereinafter.
The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which .Will be exemplified in the construction hereinafter set forth, and the scope of the ap lication of which will be indicated in the ollowing claims.
In the accompanying drawings, wherein illustrated one of various possible embodiments of my invention, Figure 1 is. a vertical sectional view taken transversely of the boiler near the front end thereof. Fi 2 is a vertical sectional view taken longitudinally of the boiler. Fig. 3 is a vertical, secto Fig. 2, showing a modified form of boiler.
Similar reference characters refer to similar parts in all views of the drawin s.
Referring now to the drawings, 1 indicates the foundation or base which supports the setting 2 of the boiler.
The fire-box is represented at3, the upper wall of said fire box being formed by an arch 4, in the front portion of which is formed an aperture 5, which may, if desired, be'connected with the ash pit. This aperture, in the present instance, lsadapted to be closed by a plate 6, although any suitable means may be employed in this relation. A stack 7 leads from the setting of the boiler near; the lower portion thereof above the fire-box. At this point it may be noted that while, in the present instance, two fire boxes havin independent stacks are employed, whic stacks may, if desired, be connected with a common fine or chimney, these portions ofthe construction are similar in all respects, and a description of one side of the boiler will, therefore, suffice to imart a clear understanding of the invention. S tack 7 is provided with an aperture 8 adapted to be closed by door 9;.and the front wall 10 of the setting of the boiler is likewise provided with a an aperture 11 adapted to be closed by a door 12. The object of these apertures 8 and 11 is to ermlt a scra er or similar instrument to e inserted 1n the space above the arch 4, and in space formed in front of the baflie 1?, which instrument may be manipulated to discharge accumulations of dust .and ashes restlng upon' the upper portion of the arch and 1n space 28.
In the central portion of the boilerls a longitudinally extending water-drum 13 from which leads a plurality of substantially vertically disposed tubes 14, the upper ends of said tubes leading into a steam and water-drum 15 which extends longitudi- "nally of the boiler near the upper portlon.
A pair of baflies 16 and 17 extend upwardly between tubes 14, and a baflie 18 extends downwardly between tubes 14 andis interposed between baflles16 and 17.
A superheater is located outside of the boiler settin above the steam and waterdrum 15, said superheater comprlsmg upper and'lower drums or headers 19 and 20 respectively, connected by vertical tubes 21. These tubes are arranged in: two sets as shown, and baffle 17 is extended upwardly, as at 22, betweenthese sets of tubes, sa d baflie terminating below the upper drum or header 19, as clearly shown in the drawin r I: willbe observed that the arran ement of the battles with respect to the tu s of the boiler, as well as those of the superheater, provide channels so that the heated gases will pass progressively from the furnace through the spaces occupied by these tubes before the same is discha izfied from the boiler through the stack 7. e course of the heated gases is illustrated by the halfbarbed arrows. The superheater is attached to the steam and water-drum 15 as by means of the conduit 24:, and the steam is discharged from the boiler through the conduit 25. Water-drum 13 is provided with a transverse artition 26 which divides the same into ront and rear compartments 27 and 28 respectively, said partition, in the present instance, being located immediately below the bafiie 17, and is adapted to compel the water flowing into compartment 28, through a feed connection 29, to flow in an upward direction through this series of water tubes, the circulation of the water being indicated by the full-barbed arrows.
It will be observed that the water circulates through the tubes 14 of the boiler, as well as in a direction opposite to that traveled by the heated gases from the furnace, and that the battles are disposed in such manner that the coolest ases are always brought into contact with t e tubes containing the coolest water. Similarly, the circulation of the steam in the superheater is always in a direction opposite to that traveled by the heated gases. This result is attained by providing a partition 30 in the drum or header 20 of the superheater, which divides the same into compartments 31 and 32 respectively, thus insuring a circulation through the tubes 21 in the direction indicated by the arrows. Blow-off pipes 33 and 31 lead from each compartment, 27 and 28 respectively, of the water-drum 13, and if desired partition 26 may be provided with an aperture in its lower portion so that the entire drum may be blown off through either of said blow-off pipes. Referring to Fig. 3, there is shown a modified form of boiler which is so constructed as to be peculiarly ada ted for the use of soft coal. In this mo ification the steam and water drum 15, tubes 14:, and baffles 16, 17 and 18, are similar to the corresponding parts shown in Figs. 1 and 2, but the water drum 13 is located at the rear of, and preferably below, the fire-box 3, between which, and the water drum, vertically extending flues or passages 35 and 36 are formed, and an arch 37 is preferably provided above the lines to protect the steam and water drum. The gasescof combustion from the furnace are forced to pass through these passages before contacting with the tubes or the water drum, whereby during their progress any smoke which may be present by reason of a too rapid volatilization of the gases will be consumed, thus insuring that the gases which will come into contact with the tubes will be practically smokeless and very hot. The boiler in other respects is similar to that heretofore described and shown in Figs. 1 and 2. If desired, the outlet 24 from the steam and water drum 15 may communicate limiting sense.
with a superheater such as is shown in said figures, in which instance, of course, the baflie 17 will be extended above the steam and water drum 15 as heretofore described. A door 38 is preferably provided at the rear of the furnace, to facilitate in the cleaning of the same.
In operation it will be seen that the gases from the furnace, when contacting with the vertical tubes 14: will first pass upward between the bafile 16 and the. front of the boiler, then downward between baflies 16 and 18, then upward between bafiles 18 and 17, and finally downward between baflie '17 and the rear of the furnace to the stack 7, and as the water within the boiler is circulating through the tubes in the opposite direction to that of the gases, it, ofcourse, follows that the coolest gases will always contact the tubes containing the coolest water and vice versa. It will, accordingly, be seen that I have provided a construction well adapted to attain, among others, all
the ends and objects above pointed out in a.
simple yet efficient manner.
By reason of the fact that the coolest gases are always contacted with tubes containing the coolest water, there is provided an economical and thorough abstraction of the heat carried by said gases. This latter advantage is also inherent in thesuperheating structure by reason of the disposition of the various parts and their relation to the baflles of the boiler proper. Another advantage accruing herein lies in the fact that the superheater being located above the boiler proper, may be readily removed therefrom if desired, or added to boilers which have been installed without such superheater.
As many changes could be made in the above construction and many apparently widely different embodiments of this invention .could be made without departin from the scope thereof, it is intended that a 1 matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of lan- Y gnage, might be said to fall therebetween. Having described my invention, What I claim as new and desire to secure by Letters Patent is:
