Specification of Letters Patent.

Patented Oct. 15, 1907.

Application filed July 28, 1904. Serial No. 218,444.

To an whom it may concern:

Be it known that I, Louis B. ALBERGER, a citizen of the United States of America, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Surface Condensers,

of-which the following is a specification.

. My present invention relates to the condensation of exhaust steam from engines, steam turbines, and other similar steam motors and to the production of a vacuum by the use of the dry vacuum system, the invention beingparticularly applicable to that class of apparatus known as surface condensers in which the condensation is effected by the contact of the steam with Water-cooled surfaces.

'The object of the invention is to promote the efiiciency of condensers by providing asurface condenser having a .very high efliciency; and furthermore to furnish a condenser of high efficiency suitable for location under a steam engine or steam turbine of which it may constitute the supporting base oi frame.

In a surface condenser the highest efficiency can besthe obtained by bringing the exhaust steam and commingled air intothe condenser at or near the bottom, and bringing the circulating water in at or near the top of the condenser,'and causing the circulating water to pass through horizontal tubes exposed to the steam, and

causing the water of condensation to gravitate against the incoming steam and air, the air being removed at or near the top of the condenser by means of a dry 3 Q vaguum pump. There are situations, however, where it is not convenient to introduce the exhaust steam into the bot-tom of the condenser, as for instance, in the case of a steam turbine, where to economize floor space and to make the connections as short as possible, the con- 3 5 denser may be placed below the turbine and may even form the base on which the turbine rests.

The inventionthcrefore consists essentially in the combination of a form of surface condenser in which the steam and eornmingled air enter above, come in contact 40 with tubes containing cooling water, by which the steam is partially condensed, and in which form of con denser the steam, air and water of condensation travel in the same direction,- with a form of surface condenser in which the steam' and commingled air enter below, pass upward and come into contact with tubes containing cooling water until the steam is entirely condensed, the water of condensation falling against the steam, and the air being rmnovcd above, or at or near the top of the condenser by adry vacuum pump. The cooling water may enter at or near the top of the latter form of combination, lml ving at or near the bottom, and enter the first form of the combination at or near the bottom and leave at or near the top; or it may pass in two passes, first through the latter form and then through the first form,

or in four or more passes, two or more times through each form of condenser making up the combination; or it may flow in parallel passes separately through each. form of the eondenser.

It is obvious that the steam may not enter exactly at the top nor pass exactly in a vertical direction in either of the forms but may pass obliquely or laterally; the object of the invention is, however, reached when the steam entering at or near the top of the condenser is completely condensed into water which comes into contact withthe steam before beingiremoyed, and when the air is cooled by tubes containing cool water immediately before being removed by the dry vacuum pump. The invention consists furthermore in combining the two forms of condensers first referred to in one structure, or. in connecting together two or more sections or divisions so that they will jointly, act like a single unit; and also, the invention-comprises various details in g the construction, arrangement and combination of parts substantially as hereinafter described and claimed.

In the accompanying drawingsillustrating my in vention, Figure l is a front elevation of a steam turbine supported on my present. improved surface condenser, the latter serving as a base for the turbine and being shown in transverse sectional view. Fig. 2 is a top plan viewof my improved surfacecondenser with the steam turbine removed. Fig. 3 is a longitudinal section with a portion in eleyation. I Fig. 4 is a top plan view of another form of my improved surface condenser. vFig. 5 is a cross-section of the same. is a. cross-section of still another form of the invention. Fig. 7 is a longitudinal section on the line a; x of Fig. 6. Fig. 8 is a crosssection of another form of the invention. Fig. 9 is a vertical longitudinal section of the same on the line 2 z of Fig. 8. Fig. 10 is a crosssection of one form of the invention, and shows in a diagrammatic way the location and arrangement of the vacuum pump, the circulating and the hot well pumps.

Similar numerals of reference designate similar parts throughout the different figures of the drawing.

A denotes a steam turbine, the detailed construction of which is not shown, as it is not necessary. This turbineis given simply by way of example in order to illustrate how my improved condenser may serve as the supporting base therefor. It' will be understood, however, that I am not restricted to any par-- ticular type of steam generator, but my condenser is adapted to be used with'all kinds of steam motors.

The frame of the condenser in the particular embodiment of the invention delineated in Figs. 2 and 3 of the drawings consists of two parts, sl1ells,\sectious, chambers, or divisions, l and which are connected together by steam passages 3; 3 and a water passage 6,

Fig. 6

for any number of passes for the water. With the particular arrangement specified, however, it will be obvi-. ous that the tubes 17 and 19, located in the top steam inlet chambers of these duplicate condensers of which we are speaking, will consist in part of tubes belonging to the pass of the water from chamber 28 to chamber 29, and in part of tubes belonging to the pass of the water irom chamber 30 to chamber 28; and furthermore that Qilf: tubes 18 and 20, located in the bottom steam inlet chambers will consist in part oftubes extending between chamber 30 and chamber 28. and in part of tubes extending from chamber 28 to chamber 29. The two upper chambers 29 are connected together by a water pipe provided with an inlet 26 (see Fig. 4), and the two lower chambers 30 are connected together by a water pipe provided with an outlet 27. (See Fig. 5.)

The circulating water which enters at the inlet mouth 26' flows first into the two upper terminal chambers 29 and thence through the tubes running from chambers 29 to chambers 28, which tubes will obviously be some of the tubes 17, the upper portion of them, and some of the tubes 18, the upper portion of them; and also through some of the tubes 19, the upper portion of them, andsome oi thetubes 20, the upper portion of them, to the opposite ends of the shells 13 and 14, where the water will enter the chamber 28, whence itreturns'through the remainder of the tubes 17 and 18 and 19 and 20 t0 the lower terminalchambers 30 and has an outlet from the condensing apparatus through the eduction mouth 27. Thus it will be seen that the tubes 17 and 19 which occupy the top steam inlet chambers 31 and 33 are progressively warmer from top to bottom, for the tubes in the lower portion of these chambers 31 andv 33 belong to the second pass of the water and when making this second pass it has been warmed to a certain extent; while the tubes 18 and 20 which occupy the bottom steam inlet chambers 32 and 34 are progressively cooler from bottom to top, since the lower part of tubes 18 and 20 belong tothe second pass of the water, while the upper portion belong to the first pass; it being observed thatjthe partitions 15 and 16 so divide the tubes thatthis very desirable and novel result is attained] Steam irom the turbine, A enters the shell 13 through the opening 21'and the shell 14- through the opening 22 and comes first int contact with some of the tubes 17 and some of the tubes 19,.whieh being connected to the chainhers 29 and bcionging to the first pass of the water are the coldest; and the steam courses downwardly in con tact with the tubes and. around the lower edges of the partitions l5 and 16 until it reaches the tubes 18 and 20 and flows upwardly in contact therewith; the water of condensation falling back into the bottom of the shells 13 and 14 while the air passes upwardly and out: through the opening 35 in shell 13, and 36 in shell 14, the air being withdrawn by a vacuum pump as indicated in Fig. 12. The water of condensationialls to the bottom oi ,the shells l3 and 14 and goes out thence.

-.th rough the outlet pipes 23 having a connection 24,

which has a coupling 25 which connects with a hot well pump. Here then the circulating water in each of theseduplicato condensers enters at or near the top of the condenser, passes in one :lireceion and then back and leaves at-the bottom. It may, however, when the two condensers operate and act as one, pass first through the second section or the one in which the air is cooled before -'the particular arrangement set forth in Figs. 4 and 5, it

exit, and then through the initial section, or the one into which the exhaust steam and air first enter, or it may pass more than once through each, or either in series or multiple, the main object being to bring the air and the last portion of the steam into contact with the coldesttubes, and to cause the water of condensation to be heated by the exhaust steamv to a temperature closely approximating that of the incoming exhaust steam before theremoval to the atmosphere. And in will be noted that the bottom steam inlet chambers 32. and 34 contain, near their top, some of the coldest tubes which are situated close to the eduction openings 35,} I

and 36 for the air, so that the air is brought into contact with the coldest tubes before being withdrawn, and furthermore the steam heats upthe water in the bottom of the two condensing shells so that when the water leaves the condensers it very closely approximates in temperature that of the incoming exhaust steam.

In Figs. 6 and 7, substantially the same construction and arrangement of parts obtains as in Figs. 4 and 5, with the exception that'in lieu of the inclined'division plates 15 and 16 I employ vertical plates 15 and 16 which lie parallel to the side walls of the condenser shells l3 and 14 and which direct and guide the movement of the exhaust steam, first toward the bottom and then upwardly in like manner asit is guided by the plates 15 and 16, the water of condensation being rejmoved from the bottom of the shells 13 and 14 by the pipes 23* having a coupling 25 by which connectionis made with the hot well pump, and the air being removed through the openings 35and' 36 under the action of the vacuum pump as is the .case in Figs. land 5.

Thus in Figs. Sand 7, there are duplicate condensers having practically the same construction and each consisting of two chambers in combination, one chamberhaving a, top steam inlet and the other having a bottom steam inlet, so that the water of condensation may be heated up to as high a temperature as possible possible before it is withdrawn.

In Figs. 8 and 9,1 have delineated another for-moi beforeremoval, while the air may be made as cold as the invention. 56 denotes the condenser shell containing three nests of water-cooled tubes, 57, 58 and 59, which nests are situated in'vertical series; that is to 1 10 say, are horizontal nests. At one end'of'the shell 56 are the two water chambers 60 and 61, and at the other end of the shell are the two water chambers 62 and 63-. The nests of tubes 57, 58 and 59 connect with these end chambers in the usual'manner, andthe'circulating water'follows the'course indicated by the arrows in, Fig'. 9, it having three passes through the condenser. The shell 56 is of cylindrical form, and the exhaust" inlet 64, instead of' beingdirectly on top is arranged laterally at the top, thus showing a;slightmodification from the form of inlet indicated in the other figuresof the drawing,'but with no change in function or purpose, for it is an upper or top steam inlet. '-'The shell 56is provided withan inner radial inclined partition 65 which divides the shell into two chambers, an upper 1 25 one having a top steam inlet, and a lower one having a bottom steam inlet. The shell 56, furthermore, has the outlet 66 for the water of condensation, the outlet 67 for the air, the water inlet 68 and the water outlet 69. a

In Fig. 10 I show a cross-section of a condenser shell suitable pipe leading from the air outlet nozzle 67 to;

the vacuum pump 75, by means of which the-cooled air is withdrawn'from' the condenser shell. Obviously the pumps 71, 73 and 75 may be constructed, each of r them, after any approved and desired pattern or'type,

and I do not'wish to be restricted to any particular design. The outline form which I delineate in Fig. 10

v is offered simply by way of example, and in order to explain the connection of one form of pump for the "performance of the function attributed to each.
