To all whom itmay concern:
Be it known that I, THOMAS H; MoGnAW, Jr, acitizen of the United States, and a resident of Oalnnont, in the county of Allegheny and State of Pennsylvania, have made a new. and useful Invention in Steamp steamor other fluids.
In Letters Patent No. 1,122,784, issued to me -on December29, 191451 show a steam separator. for the upper. drum of steam boilers or generators and an object of thisinvention is to provide an improvement over thedevice of said patent, to providea more efficient steam separator adapted for use within the upper drum of a steam boiler or generator. r I 1 A further object is to providea separator embodying new and improved details of construction.
These, as well as other objects which will readily appear to. those skilled in this par ticular art, .Ilattain in the device described in the specification and illustrated in the accompanying drawingsin which Figure 1 isa longitudinal sectional view of the upper drum of a steam boiler equipped with this inventionyFig. 2;is .a transverse sectional view along the line2-2 of Fig. 1; Fig. 3 is an enlarged view of the separator; Fig. 4 is a horizontal sectional view along line 4.4: of Fig. 1 and Fig. 5 is a cross sectional view of a number of tubes such as enter into the makeup of the separator the section being taken along the broken line 5-5 of Fig. 3.
In carrying out this invention I provide the upper drum 6 of a steam boiler or generator with two substantially identical tran verse diaphragms or dry plates 7 which divide the drum to a point well above the normal water level into three compartments, two dry ends 8 and a central chamber 9. The central compartment between the diaphragms from about the points XX will be connected to the lower drum or drums of the boiler or generator by suitable tubes (not Specification of Letters Patent.

which extend vertically from the angle 10 to the top of the drum and are trimmed in lengthso as to conformto the drum curvature. The banks of tubes are held in place by means of clamp bars 11, 12, 13 andv pipe 15 which. at its center communicates with the steam. outlet. 16 of the boiler. The
dry pipe extends into the dry ends 8 from.
which the dry steam is derived. A .filler plate" 17 closes the opening between the dry pipe and the top of the drum and a bafile plate 18 extends around the separatorv between its upper edge and the inner surface of the drum, to prevent steam from blowing from'chamber 9 into thedry ends without passing through the separator. Each of the tubes 19 making up the separator is provided with two rows of holes 20 and 21. These holesare drilledin one side of each tube and the holes of one row arestaggered with relation to those of the other row as shown in Fig. 3. The'tubes areplaced in contact one with the other so as to form chambers 22 between them. Angle bracket 10 is drilled to. provide. openings 23 which .serve as drains for the tubes.
In operationsteam generated in chamber 9 passes through the oppositely arranged separators into dry ends 8 and then out through the dry pipe. The steam first passes into the interior of the tubes constituting the first bank through openings 20" and impinging upon the imperforate wall 19 has its direction changed and issues from the tubes through openings 21. The steam issuing from openings 21 enters chambers 22 and impinges upon the imperforate walls 19 of the adjacent tubes. Having its course again changed it enters the second bank of tubes through openings 20 and issues from the second bank through openings 21* into the second chamber 22 formed between the adjacent tubes. From this chamber it enters the last bank of tubes and then passes therefrom into theadjacent dry end 8.
Thetubes on opposite sides of the drum are shown oppositely faced and as a result the arrangement of the openings 20 and 21 is different in the centrally located chambers 22 than in the other chambers. The
eated chambers 22 are shqwn b tween the seventh and eighth rows of tubes counting from the bottom of Fig. 4:.
This arrangement provides a large number of chambers having vertically extending moisture receiving walls against which the steam is projected in its passage from central chamber 9 to the dry ends and in this passage the heavier particles such as vapor or globules of water mechanically entrained by the steam are projected against and ad here to these imperforate surfaces down which they move by gravity until they pass out of the separator through drains 23 baclr into central chamber 9.
In some boilers or steam generators the upper drum may be provided with but one 7 dry end and in this case but one separator will be utilized.
In some cases it may be desirable to have plates 7 perforated so that ends 8 will contain the same level of water as central chamber 9.
The essential features of the separator shown in the drawings may be effectively utilized wherever it is desired to separate heavy particles from an elastic fluid steam.
In accordance with the provisions of the patent statutes 1 have described the principle of the operation of my invention together with the device which I new consider to represent the best embodiment thereof, but I desire to have it understood that the device shown is only illustrative and that the invention can be carried out in other ways.
Having thus described my invention, what.
I claim as new and desire to secure by Letters Patent is- 1. A steam separator, comprising a plurality of banksflof vertical tubes nested together in abutting relation so as to form vertical chambers therebetween, steam inlets to said tubes, and steam outlets arranged in staggered relation to said inlets and communicating with said vertical chambers.
2. A separator comprising a number of vertical tubes nested together so that they abut throughout their length to form chambers therebetween, said tubes being perfo' rated so that the fluid entering the first row of tubes has its direction changed before issuing therefrom into the adjacent chambers between the tubes.
3. A steam separator comprising a number of vertical tubes nested together in abutting relation and into rows that are parallel laterally and longitudinally whereby walled vertical chambers are formed between every four abutting tubes, said tubes being perforated so that the steam after passing through the first row of tubes enters the chambers between the tubes before passing through the second row of tubes.
4:. A steam separator comprising a number of perforated vertical tubes nested together in abutting relation into parallel longitudinal and lateral rows.
5. In a steam separator a row of vertical tubes arranged in abutting relation and having perforations therein on opposite sides of the points of contact between the tubes and a second row of tubes arranged similarly to the first row abut-ting against the tubes of the first row and perforated on opposite sides of the points of contact of the tubes of its row.
In testimony whereof, I have hereunto subscribed my name this 7th day of Janua ry 1918.
