RICHARD A. WHITTINGHAM, OF NEWARK, DELAWARE.
STEAM-BOILER.
Specification of Letters Patent. Patented Feb. 15, 1921.
Application led May 1, 1917. Serial No. 165,735.
To @Zlio/10m t may concern i Be it known that I, RICHARD A. VHrr- 'nner-IAM, a citizen ot the United States, residing at Newark, in the county of New Castle and State of Delaware, have Vinvented certain new and useful Improvements in Steam-Boilers, of which the following is a specification.
This invention relates to steam boilers, and especially to high pressure boilers of the sectional water tube type. Morespecitically, the invention relates to boilers of the character shown in my Patent Number 1,259,945, dated March 19, 1918.
In addition to the general objects stated in said application, the present invention seeks to provide a construction having certain advantages as to rigidity and strength, as well as improved structural details, as will hereinafter appear, and which copcrate to increase the practical utility and eiiiciency of the boiler;
In order that the invention may be readily understood, reference is had to the accompanying drawings, forming part of this specification, and in which,
Figure 1 is a typical transverse section through my improved boiler, parts being in elevation; and,
Fig. 2 is a longitudinal vertical section through the same, substantially at the center, parts being in elevation, and other parts being broken away.
Each section of the boiler, in the present invention, comprises a main header consisting of a closed tubular ring, as distinguished from the U-shaped header of my patent above referred to. A seamless drawn tube 1, of suitable size, is bent to form vertical parallel portions 1a and 1b, and has its ends united by welding so as to form a completely closed ring. This ring preferably has an apex or highest point 1C, from which the steam is collected, and a central lowermost point 1d, into which the water is fed.
The auxiliary or central header of each section consists of a pair of straight, parallel, vertically disposed tubular members 2 and 3, closed at their ends. 4 These members may be wholly independent, but are pret erably united at their upper ends by means of a U-shaped tube 4, which may be of considerably smaller diameter than the members themselves. This tube while uniting the members 2 and 8, at the same time, permits of relative movement thereof due to expansion and contraction.
Extending' between and connecting the header members liL and 2 and the header members 1b and 3, are series of cross tubes 7 and 6, respectively, such tubes being preilerably straight and slightly inclined up# wardly from the main to the central header, as in my former application.
A steam header 8 extends along the top of the boiler and is connectedwith the topmost point 1c of each main header by means of tubes 9 and 10, united by a coupling 11. Inside this header is a steam collecting pipe12, provided with small perforations throughout its length, in a manner well known in the art. From the pipe 12 e1:- tends the main steam pipe 13 to the engine (not shown), the pipes 12 and 13 being connected by a suitable coupling 14.
At the rear of the boiler proper I provide a baille plate 15 of some refractory material` and behind this battle plate I arrange a feed water heater or economizer. This is similar in construction to that shown in my former application and comprises a series of tubular headers 16. provided with cross tubes 19, around which the products ot combustion flow after passing over the baiiie plate 15.
Water is supplied to the boiler through a pipe 21, which is connected by taps 22 to the various sections of the economizer. From the economizer the heated water flows through pipe 24 to the water main 25, which extends centrally underneath the boiler. The lowermost point 1d of the main header of each boiler section is connected with the water main 25 by means of pipes 26 and 27, united by a coupling 28, and preferably welded into both the water main and header.
One great advantage ot constructing the main header members in the form of closed tubular rings is that such a configuration enables the headers to withstand enormous steam pressure without danger of deformation or distortion. Another very desirable feature ot this construction is that the lower portions 5 of the ring-shaped headers Jform a iioor on which the burner or heat generator can be supported. In the drawing I have shown conventionally a liquid fuel burner 29 of a well known type, preferably formed of two sections and shaped to conform to the curvature of the lower portions 5 of the header members. It will Vbe seen that this burner is entirely inclosed within the ringshaped headers and rests upon the sa1ne1n such a way that it can beV withdrawn, after the manner oi' a cabinet drawer. The burner can thus bereadily removed for inspection or repairs without in anyway disturbing the boiler, and no supportingmeans of any kind for the burner, other than Ythe :boiler itself, is required.
As in my -former construction, the steam passes from the central yheader members 2 and 3 downwardly through the upper tubes 6 and '7 on its way to the outlet pipe l0, and is thereby strongly super-heated.v The tube et permits equalization of pressure between the header members 2 and 3 and, as above stated, admits of free relative movement due to expansion'or contraction.'
I preferably surround the` boiler' with a heat insulating lagging 30, covered with a suitable sheathing 3l, and the steam header S and connecting pipes may be inclosed in a. housing 32. These parts have been omitted `from Fig. 2 for the sake of clearness. f
That I claim is l. Ina boiler composed of vertically aranged sections, a main header composed of a tubular ring, a centralheader comprising two tubular members extending vertically within the ring, two vertical series of tubes extending between the sides of the ring and said members, respectively, said members Y beingfree to'move laterally with respect to the ring and to one another when the tubes expander contract.
2. In a boiler composed oi vertically ar,- ranged sections, a main header composed'of a tubular ring, a central header comprising two tubular ymembers extending vertically r within the ring, two vertical series of tubes lextending between the sides of the ring and tions ot the ring and comprising two verti-V cally arranged tubes spaced apart, and two series of inclined tubes connected between said side portions and said tubes, the tubes oi. the centralheader being movable with respect to one another and to the main header when said inc-linedL tubes expand or contract.
t. In'a sectional boiler, a section comprising a main header composed of a tubular ring, a central header between the side portions of the ring and comprising two vertically arranged tubes spaced apart and closed at their lower endsya bent tube connecting the upper ends of said tubes, and twol series et inclinedftubes'connected between said side portions and said tubes', the tubes vof the central header being movable with respect to one another'and tothe main header' when said inclined vtubes expand or contract.
In testimony whereof I have aiiixed my signature, in presence of two witnesses.
