CONDENSER.

- Myyinventiomrelates to condensers such 7 as employed for condensing the. exhaust steam from steam engines or turbines, or for similar purposes.

in accordance with my invention, within a single condenser unit the condensable fluid, as steam, passes around tubes through which cooling medium passes, and passes through tubes around whlch the cooling medium passes, the condensable fluid. preferably taking the paths described in the order named. l

My invention resides in condenser structure of the character hereinatterdescribed and claimed.

For an example of one of the various forms an; invention may: take, reference is to be had to the accompanying drawing, in which: I

Fig. l is a longitudinal sectional view through structure embodying my invention. Fig. 2 is across sectional view on the line 22 of Fig. l.

Fig. 3 is'a cross sectional view taken on the line 3-3 of Fig. l.

Fig. 4iis a cross sectional view taken on the line 4 4 of Fig. l.

Referring to the drawing, O is the condenser sh'ell or body having on its ends the tube sheets S and 8 held between flanges on the shell G and the end boxes A and lid.

Lxtending through the tube sheets is a group D of condenser tubes of brass or other suitable material, around andbetween which llows the iluid to be condensed, as steam, en= tering the shell C at E, the condensate collecting}; in the bottom oi the shell U and passing; out through the outlet F to the hot well or any other suitable destination, the lower side or": the group ll) being suitably spaced above the bottom out the shell C. "l this space between the lower side nrough the group D and the bottom ot the shell til, when are structure is positioned as in dicated in l, and thence through passage at the bottom the tube sheet til flows the uncondensed steam and any un condensable fluid in mixture therewith, air, into the chamber H beneath the parti= ticn It in the end box A. The chamber H, as indicated in Fig. 3, extends to one side and upwardly in the box A between theouter wall of the box A and the extensions l? and l of the aforesaid partition l fjcm- 1921. serial No. 485,208.

niunicating with this lateral portion of the chamber H are the condenser tubes of a group J extending through the tube sheets S and Si within the shell 0, and between it and the partition plate or wall J extending longitudinally of the shell 0 between the same and between the tube sheets S and S the tubes of the group J discharginginto the chamber 1K in the end box B, Figs. 1 and 4, such chamber being form'edbe tween the shell (3 and the partition havin the section or portion L, corres onding wit 1 partition ii in box A, the section L corre- .ponding with the partition I in thebox A, tie section L corresponding with the section l in the box A, and the sections L and L The mixture of steam and air discharged trom the tubes J into the chamber lit passes through said chamber from left toward the right, Fig. 4, and enters the condenser tubes of the group M extending between the tube sheets S and S and disposed within the shell (l between the shell and the inclined wall or partition N substantially in register with the section L or" the partition in the box B. The tubes of the group M deliver into the chamber Q, Fi 3, disposed between the outer wall of tie chamcr A and a artition P, coincidirn with partition N. ubstantially nothing but air reaches the chamber U, and this is discharged or drawn oil b suitable pump, ejector or the like throng the air outlet Q,

The cooling water enters at and is de livered divided streams through the passages lt and into the chambers wit? the shell C containina respectively, tube c n In oroups M and J, The cooling we s r 0 according j flows arounuthe tubes groups at d M, o e

thereafter through the openings l in the tube heet 6 into the chamber the box 1; above partition ll ich chamber communicate tubes of he group the cooling water tlowing through the tubes D into the cl her in the box A above the partitions a 1 l P, the water then through the water outlet The incoming steam theretore cornea into contact with tubes of the group through which cooling water is hoping, such condensa e as has been termed passing;

through the condensate outlet F; the uncondensed remainder then passes into the chamber H of the box A and thence through the tubes of the group J to the chamber K in the box B, and thence through the tubes of the group M into the chamber 0 in box A, and the air passes otlthrough the outlet Q.

The cooling water passes in divided streams first around the tubes of the groups J and, M, and thence through the tubes of the group D. 1

The water resulting from condensation of the steam passing through the tubes or" groups J and M is drawn oil in any suitable manner, as from chambers K and U, respectively, as through the draw-off connections Y and Z4, respectively.

By an arrangement of the character above described, a greater amount of steam, other things being substantially the same, may be effectually condensed with a given amount of cooling water with a smaller amount of heat transfer surface, that is, with fewer condenser tubes or shorter condenser tubes, or in general, with less tube surface, Ur with a given tube surface and given cooling water conditions, greater amounts of steam may be condensed,

ti hile have described a form of my apparatus wherein the steam first flows around tubes through which cooling Water is passed, and then through tubes around which cooling water passes, it will be understood that the reverse arrangement may be employed.

As shown by Fig. 2, the group of tubes is disposed between the shell (3 and the downwardly inclined and-convergent partii tions 5 and N, between which latter the shell are disposed the other tube groups. this arrangement, the steam passing aro ind the tubes of the group D is progre" siv 1y condensed and thereby diminished amount, and with the path diminishing cross section as enforce by the converg, partitions d and li the velocity of the steam remains substantially constant. In addi tion, the condensate produced around those tubes vertically above the partitions d N collects upon those partitions and descends along them to the bottom of the shell, By this arrangement, there are procured the advantages of the so-called a -shaped surface condenser, and the space between the partitions and the shell is usefully employed for the tubes of final condensers or coolers ld hat I claim is:

i. A. condens unit comprising at least three groups of tubes, the first group com" prising the greatest number of tubes, and the other groups comprising lesser numbers tubes, means for passing the fluid to be used first around the tubes of said group and thence through tubes of said other groups in succession, and for passing cooling water first around the tubes of said other groups simultaneously and then through the tubes of said first group.
