"'Be it known that I, Divm'w; R. ew,

a" citizen of the "United States, and aresiidenser swarthmore, in, the county of Delawere Le'nd State of Pennsylvenia,fhavein-' vented a new and useful Improvement in Larg Jet Condensers, of which-the follow- -in isa specification. r v

and has for its object to provide apparatus of the eharaoter designatecl which shall be flexible in its. operating characteristics and which, at the same tirne shall be relatively compact in size and economical in material for the eapecity involved. b

Having thns described the condenser embodying my invention, the,operation:-is as follows: Exhaust steam flows from the turbine 12 into the inlet chamber 6 and there encounters 1' the 'i-spr'ays projected from the nozzles .8. By the'use of aninletchamber. of an elliptical plan view, a reduced amount of water is required and a relatively low degree of vacuum sufltices to maintain sulficient head on the nozzles to cause the sprays to fill the-whole of. the inlet chamber. Thus slight difierences in the degree of vacuum as brought about by different loads on the turbine, diflerent temperatures of cooling ater, and defectsin the operation of the air removal means, are ineffective in'interfering with the distrib-ution. of the sprays Within the inlet chamber, as wouldbe the case were this inlet chamber "of circular view and of equal capacity as the attendant necessary of relatively long sprays. Moreover by employing a common inlet chamber',- the necessity for pressure-equalizing connections between the inlet chambers of the twin-unit condensers, now commonly jused with 'tu'rbinesof the double flow type, is eliminated and consequently both the length and the area ofthe connections'between the turbine and condensers can be materially reduced. T

The condensate' rains down through the ,bafile ,13 and,. un der; full load conditions, is divided by the -;bifurcated member 19 and onerhaljf thereof is ejectedby each of the condensatepumps. I r

-,Under'conditions of light load, but one i .set ofaux'iliaries may be operated, the noncondensiblegases readily flowing across the large mixing chamberprovided and all condensate passing either directly or through the conduit ".to the one condensate pump 1n operation.

I ",the event that one set of auxiliariesis disabled, by oyerloading the remaining set, the fullloadon the turbine may be'approximatedw C Wild ha e rrn y inve t i b one form, .:it,. will be obvious to those skilled inthe art that is not so limited, but is sins ceptible of ,varinus other changes and modi- .fications. without departing from the spirit thereof, and. I desire, therefore,- that Qnly limitations {shall be placed thereupon as are ,imposed by the prior artor as are spec fically set forth in the appended claims.
