In the drawings accompanying and forming a part hereof, Figure 1 is a diagrammatic illustration of a condenser installation embodying my invention.

Fig. 2 is a sectional view along the line 2-2 of Fig. 1.

As illustrated the apparatus includes a condenser 3, provided with an inlet port 4, a condensate delivery port 5, and an air oif take port 6. The inlet port 4 is adapted to communicate with the exhaust of an engine or turbine delivering steam to be condensed. The air ofl'take port 6 is shown in communication with an ejector 7, receiving motive fluid, for example steam, through piping 8 The discharge end of communicates with an air sepprovided with an air vent port 11.

As illustrated, the pipe 16 is: providedat its end, and .within the separator, with aj'riozzldaxliiclr is locatedabove the normal water separator. and isatla ited densate in the form 'of spraypor separate streams to the separator. its illustrated in Fig. 2,; thewate'r discharge pip e,.1,7.-of the separator Connn'unica with a feed Water, An object of the'invention is to produce lanlclS and 'r-eeeiveswan-ioverflowing a weir '19, located within the separator, 1.0.

condenser is receiving steam to. be condensedi through the port g'the water of condcnsa tion is rator 10.' The steam gases, such as and air, issuing from the discharge. 7, are also delivered .to' the by the cooling and condensing action. of the .watcr of'condensation and the air is liherated, the overflow from the separator 10 delivered by the pump 14 to the scpa 7 IIOIl-COlltlQ-Ilstlbltl being deliveredto the feed water tank 18 I and ultiii'i'ately tti'th'e l' o't "well or back' tothe steam generator through deliverygpoi't 20. In this way the separator performs the three-fold function of separating the air, heating the feed water and condensing the steam from the ejector.

When the prime mover or engine is not in operation or when it is operating under such light load that the steam delivered by it to the condenser is not sufficient to provide snflicicnt water of condensation to condense or fully condense the steam issuing from the ejector 7, "steam will be lost by blowing out through the vent port. 11 of the separator to the atmosphere. In order to prevent this, I have provided means for dolivei'ing water of condensation or water from the tank 18 to the condenser for the purpose of providing suliicient water to complete the condensation of steam in. the separator 10.

In the illustrated embodiment of the invention, this is accomplished by providing piping 21 between the tank 18 and the condenser 3 which terminates within the tank below the surface ofthe water contained therein, and within the condenser in a spray nozzle 22. This nozzle is preferably located in the upper portion of the condenser and is arranged to so deliver the water issuing from pressure will force water through the piping into the condenser when this valve is open.

WVith this arrangement, water may be delivered from the tank 18 to the condenser either for the purpose of augmentlng the condensate delivered to the pump 1f]: during light loads on the engine or turbine, communicating with the port 4, or forithe purpose of providing the entire supply of condensing water delivered to the separator 10. The water issuing from the nozzle 22 is cooled in its passage over the tubes of the condenser and consequentlyis effective as a condensing agent Within the separator. This, therefore, prevents wasting of the steal issuing from the discharge of the ejector While I have described but one embodiment of my invention, it will be apparent to those skilled in the art that various changes, substitutions, additions and omissions may be made in the apparatus illustrated without departing from the spirit and scope of the invention as set forth by the appended claims.

What I claim is: p

- 1. In combination with a main condenser, a steam actuated ejector for withdrawing noncondensabla vapors from the condenser, an auxiliary condenser having an atmospheric vent port, aliquid discharge port and a fluid inletport, a spray nozzle located within the auxiliary condenser for delivering a Water spray in the path of travel of fluid enteringthe fluid inlet port and movber, 1915.

ing toward the vent port, means for delivering water of condensation from the main condenser to said spray nozzle, means located within the auxiliary condenser for retaining a body of Water between said fluid inlet port and the atmospheric vent port, a fluid distributing nozzle communicating with the fluid inlet ort and located below the surface of the ody of water so retained, means for delivering fluid discharged from the ejector to said distributing nozzle, and

-1neans for returning water of condensation auxiliary condenser and communicatin with said liquid inlet port, and arranged to deliver a. spray of condensate between the fluid inlet port and the vent port, means within the. auxiliary condenser for retaining a body of condensate and for forming a weir over which condensate flows from the body to the liquid discharge port, and a fluid distributing'nozzle located below the surface of the body of condensate so retained and communicating with said fluid inletport.

In testimony whereof, I have hereunto subscribed my name this 21st day of Octo- MAURICE LEBLANQ. Witnesses:
