The steam entering densed in well known mannerfi'n'to water, which is the condensate whic'h collects in the bottom of "the shell C in the hot well or other receptaclefH. Disposed Witl1- in the hot Well is the nozzle N "ofejector apparatus comprising inaddition the diffuser guides 'or mixing cones B and B. disposed'in alinement with the combining tube or difiuser D which in turn delivers directy, or indirectly through any suitable length of pipe, into the centrifugal or other of pump P driven by the steam turbine T or any other suitable motor, as an electric motor. "When the motor T is asteam turbine it receives steam. through the pipe s and exhausts it through the pipe .5- con Branched from the exhaust pipe 8 is the pipe U controlled by valve V and communicating with the pipe 8" communicating with the nozzle N and controlled by the Valve Y. Communicatis another pipe 8 connected with any suitable source of motive fluid, as liv valve V". Upon the upper surface W of the condensate. collected in the bottom of hot well H is the float secured the. condenser C and -F carrie'd o n the end of the lever m upon the pivotal v shaft 2. which extends througha vacuum tight joint to the exterior of the condenser shell C where there is secured thereto the link. X pivoted at a to the link to pivoted at to the link, 2 whose other end is secured upon the pivotal shaft o uponwhich is secured the valve With the valve V closed and the valves V and V? open, the steam turbine T drives the pumps condensate from the and discharges the same against at E is c0'nmay be removed e steam, and controlled by the atmospheric or any other pressure, the exhaust steam from the turbine T passing through the pipe 8 and through the valve V to atmosphere, or to a condenser, feed water heater or any other suitable point. Simultaneously live steam admitted through the valve V and pipes 8 .9 passes the open valve Y to the nozzle N and in expanding causes to be drawn into the members B, B and into the diffuser D the condensate in the hot well H, delivering the same at higher pressure to the pump P, thus causing the pump P to operate with an effective submergence greater than that due to the height of water level W in the absence of the ejector.

Or with the valves V and V closed and the valve V open, theejector nozzle N is supplied with exhaust steam from the turbine T, in which case the action is similar to that above described.

Or when using exhaust steam as described live steam may also used by partially opening the valve 2 and thereby throttling the live steam toa pressure substantially the same as that of the exhaust steam. Or exhaust steam from any other source than the turbine T may be employed; for example, the exhaust steam from the turbine or engine driving the pump which supplies the cooling water to the condenser.

The motive fluid delivered to the nozzle N is controlled by the float F. In case the water level V falls, the float F descends and through the system of levers described moves the valve Y toward closed position, thereby shutting off more or less completely the supply of motive fluid to the nozzle N, with the result that the ejector removes or assists in removing'less condensate, thereby causing the level to again rise .to maintain proper submergence of I the ejector. And in case the water level W falls sufficientlv, the valve Y will be completely closed until the water level rises sufficiently, in which case the float F will again open. the valve Y.

Referring to Fig. 2,-the airopening O is shown as communicating with an ejector having the nozzle 1% to which steam or other suitable motive fluid is supplied, thereby drawing air from within the condenser O and compressing it, the motive fluid and entrained air being delivered to the second ejector whose nozzle is N supplied with suitable motive fluid, as steam, which entrains the motive fluid and air from the first ejector and delivers the same through the discharge nozzle D which acts as an ejector motive fluid nozzle terminating within the hot well H in front of the diffuser I) open at its end and submerged within the condensate in the well H and delivering into the chamber L having the weir partition Q, the air outlet O and the condensate outlet O from the condensate and passes out through The first ejector whose nozzle is M withdraws air from the condenser C and compresses it, delivering the same into the second ejector whose nozzle is N, which then delivers the air and motive fluid through the nozzle D into the diffuser D, further in creasing the pressure of the air, and drawing into the diffuser D condensate from the hot well H and delivering both air and condensate at atmospheric pressure or any other suitable pressure above or below atmospheric into the chamber L, where the air separates the opening Oflwhile the condensate overflows the weir partition Q and is drawn off by pump or otherwise through the outlet 0".

In. Fig. 3 the air outlet O connects with the ejector whose nozzle is N which withdraws air from the condenser O and raises its pressure and delivers the same and the gmotive fluid through the discharge nozzle D which terminates within the hot well. H in front of the guide tube or cone B which is submerged in the condensate. The tube B extends horizontally through the downwardly extending wall or partition structure in the form of tube G, open at its lower end and connecting at its upper end with the condensate outlet of the condenser C This causes the condensate to flow downwardly throughthe tube G before entering the bot well H, and thereby forms a trap or seal to prevent air delivered by the ejector from risingdirectly back into thecondenser, which would result in again lowering the vacuum and in effect rendering the ejector useless so far as air removal. is concerned. The outlet of the tube B is disposed in front of the diffuser tube D whose outlet end is upwardly turned and terminates within the air separating chaml'ier L, whose air outlet O connects with the air pump K and whose (ZOIlQQflStllS outlet O communicates with the suction of the condensate pump P, both pumps K and P being driven by any suit-- able motor, the steamturbine T;

In this case the ejector withdraws v air from the condenser C and compresses it to a pressure at least as great as that ccrresponding with the submergence of the discharge nozzle D below the water level In issuing from the tube D which acts as a motive fluid nozzle for the submerged ejector, the steam of the mixture is condensed, there y producing a vacuum, which causes condensate to be drawn into the tube B, and due to the momentum of the condensate so attained it is delivered by the tube B to the tube- D with suflicient velocity to cause it to issue from the tube D within the chamber L at a still higherpressure, This pressure generally being below atmospheric pressure, an air pump K increases the pressure of the air separated in the chamber L to atmospheric pressure or any other suit- 0 able pressure, and the pump P simultaa neously removes the condensate to any suit-- sure.

In Fig. 4 the air outlet of the condenser communicates with the ejector whose nozzle I to the discharge nozzle D of a second ejector terminating and pointing upwardly within the air separating chamber L. Diswhich actsas the motive fluid nozzle for the submerged ejector, are the cones-or guide tubes B and B, the former supported by webs or ribs 7* upon the tube B, which in suitable motor.

Vertically alined with the tube B i'sjthe funnel J having its receiving orifice within the chamber L and delivering to an ejector whose nozzle is supplied with steam or other motive fluid from any suitable source. In this case the ejector whose nozzle is M withdraws air from the'condenser C and raises its pressure, the mixture of motive fluid and air being discharged by the nozzle D into the condensate, whichcondens'es the steam, producing a vacuum which assists the jet issuing from the nozzle D to draw condensate into and upwardly through the over the top edge of the tube B into one compartment of the chamber L from which it overflows the Weir partition Q into the second compartment, from which it is withdrawn by the pump P. The air separates from the condensate and passes out through the funnel J to the ejector whose nozzle is R, which further raises the pressure of the air to atmospheric pressure or any other desired pressure. j i

It will be understood that the weir partition Q may be omitted, and the top edge of the tube B may constitute a weir over which the condensate flows to the outlet orifice O j i In Fig 5 C represents the bottom portion of a condenser shell, such, for example, as used on board ship. Both air and condensate are withdrawn through the outlet 0, the condensate collecting in the hot well or other receptacle H within which is submerged an ejector whose nozzle is N, which receives steam or other suitable motive fluid. The nozzle N is alined with the guide ring B, which in turn is alined'with the diffuser D communicating with the suction chamber 3 of the pump P The air passing out from the condenser through the opening passes upwardly to the ejector Whose nozzle M is supplied by steam or any other suitable fluid. This ejector raises the pressure able higher pressure, as atmospheric presis M, the ejector delivering through the tube %osed in vertical alinementabove the nozzle 1 tubes B and B, delivering the condensate "Y to proper degree.

of the air and delivers it together with the motive fluid intothe condenser C in which the motive fluid is more or less completely condensed, the condensate passing onw ardly to the suction chamber S, as does also the air, the condensate and air-being removed from the suction chamber S by the pump P which may be any suitable type or pump, but preferably a reciprocating wet air pump. The ejector whose nozzle is N imparts pressure and velocity to the condensate and delivers the same at higher pressure to the suction chamber S in assistanceto the pump P In Fig. 6 the float F, responsive to changes in level of the condensate in the a hot well H, controls the valve Y which controls the supply of steam or other motive fluid delivered by pipe 8 to the ejector whose nozzle is N disposed within a chamber X through whose wall extends the guide tube or cone B into a hot well H in alinement with the diffuser tube D whose inlet is within the hot well H' and which discharges into the air separating chamber L having the air outlet 0 and the condensate The air outlet 0 of the condenser communicates with a steam or other ejector Z, which withdraws air from the condenser and raises it in pressure and delivers it at higher pressure into the chamber X. From the chamber X the motive fluid and air from the ejector Z is drawn by steam issuing from the nozzle N through the tube B, which acts as a. motive fluid nozzle ofthe submerged ejector, into the hot well H,"where condensation of the steam takes place, producing a vacuum which assists the jet from the tube B in drawing condensate into and forcing it through the difiuser D and delivering the, same at still higher pressure into the air separating chamber L. I

As the level W of the condensate falls. the float F falls and moves the valve Y toward closed position, thereby reducing the amount of steam supplied to the nozzle N, and thereby causing the motive fluid issuing therefromto remove less condensate from the chamber H. In case the level WV falls far enough, the valve Y will be completely closed. And as the level of the condensate rises again due to. accumulation of condensate, the float F will rise and open the valve In both Figs. 1 and 6 the float F may control the action of the ejector in any suitable way as by adjusting an adjustabl diffuser or adjustable nozzle, or both.

While the ejectors herein disclosed are of simple single nozzle types, it will be understood that any suitable forms of ejector may be used, as for example, those employing a plurality of steam nozzles, or ejectors having annular nozzles and diffusers, or ejector-s of the latter type in which the diffuser is disposed outside of and surrounds the annular nozzle which discharges radially into the diffuser.
