THE NORRIS PETERS ca, PHOTO-LITHO. WASHINGTON. v.
CHARLES S. HOOPER AND ROBERT C. STEVENS, OF ERIE, PENNSYLVANIA.
STEAM-SUPERHEATER.
Application filed October 27,
We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters'of reference marked thereon, forming part of this specification.
This invention relates to steam superheaters of the type in which the steam is received in a drum to which return bend heating-tubes are secured.
The object of our invention is to produce a steam super-heater of this type in which there is provided means by the operation of which the heating-tubes are caused to operate as a series of groups of tubes, so that steam on being received into the drum will enter and pass through one group of tubes, and then enter and pass through another group of tubes, which operation is repeated as many times as there are divisions of heating tubes into groups.
A further object is to so construct the interior mechanism of the super-heater that it may be readily placed within, and removed from the drum.
The features of our invention are hereinafter more particularly pointed out and are illustrated in the accompanying drawings in which:
Figure 1, is a side View in elevation of a steam-super-heater embodying our invention. Fig. 2, is a horizontal central section of the same, through the drum, looking downward. Fig. 3, is a transverse section of the same, on the line iU-U in Fig. 2, looking in the direction of the arrow. Fig. 4, is a transverse section of the same on the line yg in Fig. 2, looking in the direction of the arrow. Fig. 5, is a transverse section of the same on the line zz in Fig. 2, looking in the direction of the arrow.
In these drawings, A, indicates a drum, and a-a, indicates metal rings secured in the ends thereof, to which the drum-heads B and B, are secured in the usual manner. One of these heads B, is provided with an opening 6, and the other with an opening I),
Specification of Letters Patent.
1913. Serial no. 797,552. r
with which steam pipe connections C, and C, communicate. In the shell of the drum A, are secured return-bend U-shaped heating tubes D, D, and D in such a manner that their ends are in rowslongitudinally of the axis of the drum A, and the two ends of each tube are located on lines at right angles thereto.
Within the drum A, we place an open face box-like member E, which covers the Patented Jan. 19, 1915.
exit ends of the tubes D, and the entrance ends of the tubes D, and beside this member E, we place another box-like member E, so, that it will cover the exit ends of the tubes D, and the entrance ends of the tubes D and endwise with the member E, and beside the member E, we place another boxlike member E so that it will cover the exit ends of the tubes D From the last E of the box-like members, a tubular duct F, leads to the opening 6, in the head B. While we show the exit opening I), to be located in the head B, we do, when it is desirable,place the exit- 5, in the shell of the drum, and likewise; opening Z), for the admission of steam may be placed in the shell of the drum A, when desired. 2 7
To secure the members E E, and E in their places over the ends of the tubes as above described, straps G, are placed over them, the ends of said straps being secured in a removable manner to the shell of the drum,'preferably by means of tap-bolts g, secured in the shell of the drum A, and
and E can be inserted through the rings a,
and placed over the tube ends as above described, and the strap G, secured in place thereon, so that the members E E, and E will be retained in their proper positionsas above described, no matter what the position of the super-heater may be. Owing to the liability of the return-bend tubes becoming damaged, and the necessity of having to remove such damaged tubes and replace them with new tubes, the removability of the members E, E, and E is an essential feature of our invention, as otherwise it would be impossible to make such repairs.
In operation, steam is admitted into the drum A, through the opening 7), in the head B, so that the drum A, is filled therewith from end to end around the box-like members E, E, and E Owing to the baiiiing effect of the members E, E, and E the steam readily enters the uncovered entrance ends of the tubes D, and passes through into the box-like member E, and moves longitudinally therein to and enters the tubes D, and passes therethrough into the boxlike member E, and moves longitudinally therein to and enters the tubes D, and passes therethrough into the box-like member E, and moves longitudinally therein to, and enters the tubes D and passes therethrough into the box-like member E and moves longitudinally therein to the tubular duct F, which conducts the steam Which has passed through the tubes as above described, to the exit opening I).
It will be observed that in the arrangement of this super-heater, no packing is used between the members E E, and E and the shell of the drum A, or between the duct F, and the outlet 6, but-that owing to the fact that these members are completely surrounded by steam at approximately uniform pressure, such packing is unnecessary, and that steam, on entering the drum A, will take the easiest route to travel, Which owing to the bafliing box-like members E E, and E is through the tubes D, D, and D in succession.
It Will be observed from the foregoing, that the box-like members E E, andE While separating the super-heated steam Which is passing through the tubes from the saturated steam Within the drum A, they also serve as mixing chambers, wherein particles of steam Which have passed through each of said tubes 1) D, and D are thoroughly inter-mixed before leaving each of said members.
Having thus fully shown and described the construction and operation of our in vention, What We claim as new and desire to secure by Letters-Patent, is
1. In a steam super-heater, the combination of a drum to receive steam, a series of return-bend tubes having their ends secured in the shell of said drum, an open-faced box-element longitudinally situated Within said drum and inverted over the right hand ends of said return bend tubes, and another open-faced box-member longitudinally situated Within said drum beside the first mentioned box-like member, inverted and extending over the left hand ends of said tubes part Way from the exit end of said drum toward the entrance end thereof, and a tubular duct leading from the last of said box-like members to the exit opening from said drum, substantially as set forth.
2. In a steam super-heater, the combination of a drum to receive steam, a series of return bend tubes having their ends secured in said drum shell in longitudinal rovvs, a series of open-faced box-like members inverted over one roW of said tube ends, and a less member of said box-members beside, and so arranged as to overlap any two of the. first mentioned box-like members and cover all but a few of one end of said return bend tubes, and a duct leading from the last of said box-like members to exit opening of said drum, and means to secure said box-like members in place Within said drum, substantially as set forth.
In testimony whereof We afiix our signatures, in presence of two Witnesses.
