' CONDENsiNG arriiRArns.
To all whom t may concern Be it known that l, PAUL A. BANGEL, a
citizen of the United States of America,
residing in the city, county, and State of New York, have invented certain new and useful Improvements in Condensing Apparatu's, of which the following'is a true and exact 51 description, reference being had to the accompanying drawings, which forni a part thereof.
My present invention yrelates to condensing apparatus such as the surface condensers employed foi` condensingthe exhaust steam from steam motors,in `which the vapor to be condensed is passed into a condensing chamber and into contact therein with tube or `other. wallsv exposed externally to the condensing chamber to acoolingfluid.
1 The object of the present invention is to improve condensing i apparatus ofthe rkind described by providing novel and elective means for `regulating. the distribution ofv steam throughout the condensing chamber,
and for aiding in the removal from the con densing chamber ofthe air or other noncondensable vapor or gas tending toaccumulate therein, with the ultimate` object ofv increasing the efliciency of the condensing apparatus andof facilitating lthe mainte? nance of a high vacuum when this is desired.
l accomplish the desired 1results yby providing means for so directing jets of steam, which may be either high pressure steam or low pressure. steam as conditions inake desirable, into appropriate portionsof the cony densing space, to therebyproduce the desired circulation of the air vor other non-2 condensable gas ork vapor as well as of the steam to bev condensed. D The use of suchi circulation controlling provisions not only adds to the eliciency kof surface condensing apparatus of practically every type, but` makes it possible to operate condensing ap-` paratus with ar general.direction` of flow therethrough which is independent of gravity, and ofthe relativedensities offsteam and non-condensable vapors or gases at varyi ing temperatures.y
Theinvention is ofiparticular utility in .connection with condensers of relatively large size, and the modern development [of power plants tends constantly toward unitsof larger size. unit increases thek paths .to be traversed by the steam and air increase in length, and thei As the size of acondenser or NEW "YORK, N. Y., Assienort rro riiivIsELE, AND @frissonner urrnrt'iaionrotfin, NEW TER-snr.

`tendency of airor `ratheran air-steam rmixture rich in air to colleetand stagnate, and
thereby prevent the proper `distribution of steam in certain parts of the condensing space `also increases.
For a kbetter understanding ofthe invention, however-,and of the advantages possessed` by it, reference shouldpbe made to the accom*y n panyingfdrawings and descriptive matter in which l,r have illustrated forms in ywhich rmy inventionr may be embodied. l e Of the drawings: Figure l is an elevation partlyk in section of oneform of condensing apparatusembodying invention. Fig. 2`
:is a partial sectional `elevation takeiivonthe line Q-ffof Fig.` l. Fig. Sis a transverse. sectional,` elevation y, ofy a modiliedform of condensingV apparatus; and Fig. l is a transversesectional elevation of a third form of condensing apparatus embodyingl my inveny ln the drawings, and lreferring firstffto the construction shown in Figs. l and Qffr represents .the shell or housing of a surface condenser of well known type, provided with a steam inlet A` opening to the `top of thev condensing chamber, and a water outlet A2 opening from thev bottom of .theV condensing chamber and with air` outlets A3 leading from the sides of the condensing `chamber adjacent its bottom.
B represents the usualfcooling water tubes .y
. p assing through ythe condensing chamber.
As shown, the tubesare grouped to. provide a central Estea'm; space At in the condensing chamber and` verticaly channels A5 at the sides of the condensing chamber.y
lnolined rain plates or badles are arranged `atvarious elevations in the condensing chamber. ,Theseconvey the waterof condensation formed in n .the inter-space iminediately` above each plate to the adjacent side channel A5, thereby preventing the water from droppingdown onthe `subjacent tubes B. .They also providey denite flow channels. kl) represents steam jet `,noz-r ales disposed at appropriate placeskin the densed and ofthe air or other non-con*- -densable gas or vapor adinixed` therewith.`

As` shown` in Figs. l and 2, the nozzles D are directly connected to and receive steam trom pipes E, each of which is provided with a plurality of nozzles D. Each pipey be regulated or entirely cut onf as desired.
To increase the `aspirating effect of the steam jets issuing from the nozzles D bai' fles G may be employed as shown. In the condenser shown in Figs. 1 and 2, the outlets A3 for air and other non-condensable gas orvapor are connected to auxiliary condensing and vacuum producing apparatus which as conventionally illustrated comprises a small supplemental condenser H and an ordinary dry air pump I. B represents cooling` water tubes which may be located adjacent the` airI outlets A3 `to cool the liuid passing through theflatter. The steam supplied by the pipe `F may be live steam t'romr any readily available source, or it may be low pressure steam, drawn for instance, 'from an `intermediate stage of a turbine where, as in the particular construction shown in Figs. l and 2, the pressure in the condensing chamber is yintended to be below that of the atmosphere. It is to be understood, however, 'that the invention is not limited to use in condens` ing apparatus in which a vacuum is maintained in the condensing chamber, but may also be employed in connection with closed feed water heaters or evaporators and like apparatus in which the pressure within the l condensing space is at or above atmospheric pressure. To obtain an effective distribution of the steam in the condensing cham-1` ber, and to materially aid in the removal of 3 air and uncondensed gas or vapor by the use of steam jets in accordance with the pres-` ent invention, requires but a relatively small amount of steam to be discharged by the jet nozzles and resultsfin 'very greatly increasing the efliciency and capacity of the condensing apparatus.
In the modified form of my invention shown in Fig. 3, `A A represents the condenser casing, kA10 the steam inlet to the upper end of the condensing chamber, A11 the water of condensation outlet, and J the outlet for air and other uncondensed gas or vapor. In this form of my invention the jet nozzles D A are arranged so that in conjimction with the baiiies C A which extend like theblades` of a fan from `the pipe J as a center, they cause the steam and other gaseous fluid to flow downward and toward the center of thecondensing chamber.
The form of my invention shown in Fig. l is a variation of that shown in Fig. 3, in
which the nozzles D B and battles C B are so disposed that the'circulation is toward `the center of the top of the condensing chamber. As shown in Fig. 1l, the steam inlet A100 opens to the condensing chamber A B at the bottom, while the outlet A110 Jfor air and other uncondensed gas or vapor leads from the top of the condensing chamber.l lith this arrangement the water of condensation ypassing out ot the condensing chamber at the bottom through the outlet A120 approxii mates the maximum possiblev temperature: to wit, that of the incoming steam, with which it is in contact, while the air and other gas or vapor passing out through the air outlet A110 is well cooled. These are important advantages, since where the water of .condensation is used as boiler feed water, as is usual, it adds to the efficiency of the plant, of course, to have it at the maximumtemperatu-re possible, while Vit is desirable tohave the gaseous fluid passing out of the condenser as cool as possible, for the reason, among others, that it reduces the duty imposed upon the dry air vacuum pump. Furthermore, the construction shown in Fig.V t per mits the condenser to be located on the same floor levelwith the yturbine orjother steam engine from which it receives steam, and to be connected thereto by relatively short and simple exhaust steam connections. These advantages `are highly desirable, but ordinarily are secured at a sacrifice of eiiiciency,
becauseair which collects in the top of the condenser being heavier than steam, tends to flow down, rather than upward toward the air outlet. l
Certain'features of invention disclosed but not claimed. herein are claimed in my copending .application Serial No. 734,050 filed of even date herewith,
W'hile in accordance with the provisions of the statutes I have illustrated and described the best forms of my invention now known tome, it will be apparent to those skilled'in theart that changes may be made inthe form of the-apparatus disclosed without departing from the spirit of my invention, and that under some conditions certain features of my invention may be used without alcorresponding use of other features.
, Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:
1; 'In condensing apparatus of the surface condenser type, the combination with the condensing chamber and its main steam inlet, and water, and air and vapor outlet provisions, ot means for discharging jets of steam into said condensing chamber to thereby regulate the distribution therein of the steam entering through said main inlet,and the discharge of air and vapor.
