JOHANN STUMPF, OF CHARLOTTENBURG, GERMANY.

SURFACE-CONDENSER SYS'IlEM.

T 0 all whom it may concern:

Be it known that I, JOHANN STUMPF, a subject of the Emperor of Germany, residingl at Charlottenburg, German have invented certain new and usefu ments in Means for Obtaining a'Vacuum in Surface-Condenser' Systems, 4of which' the following is a specification.

My invention -relates to surface condenser systems, and has for its object to improve t em whereby a single ump ,may be utilized to remove the water of) and air from the condenser, and also to circulate the cooling water through the tubes.

In the accompanying drawing, which illustrates one of the embodiments of my invention, is shown a surface. condenser s stem.

1 indicates the casing of a su acecondenser having an inlet 2 for thev steam exhausting from a turbine or other steam-consuming device, and an outlet 3 for the escape of water of condensation, uncondensed steam and air. In the ,casing are tube sheets 4 that su port the tubes 5 through which the circu ating water is forced.A hambered heads 6 and 7 are provided on opposite sides ofthe condenser.

Situated below the condenser is a' centrifucasing and above the impeller is a receiving chamber 13 that is in direct communication with the outlet fioiii the condenser, and through the passage or opening 14 with the chamber 15 in the impeller, and also with the.

chamber 16 containing the im eller. Extending downwardly through tie receiving chamber 13 and into the chamber 15 is a conduit 17 through which cold water iiows from the cooling tower or other receptacle 18 by the pipe 10. The lower end of theconduit 17 is, llared after *passingl through the opening 14 so as to effectively discharge the cold water directly to the blades of the'inipeller.

The mixture'from the discharge chamber 12 passes by the pi e 2() into the chamber in the head 6 from w iich it flows through the tubes into the chamber in the head 7. From the latter the warm `water iows by the pipe Specification of Letters Patent.

exhaust steam after leaving the condenser.

comes in direct contact with the cold cooling Water before it passes into the tubes of the condenser proper. The coolin water under pressure'flows from the conduit 17 into the chamber 16 of the impeller as a free jet. By

Avirtue of the velocity of flow of the cooling water the gas ressure prevailing in the chamber '16 will eas low as that in chamber 18 or even lower. By'the suction effect of the jet of cooling water as well as that of the centrifugal pump, the mixture of steam and air is sucked out of the chamber 13 through the orifice 22 into the chamber 15, during which action the steam is condensed by contact with the cooling water and the air passes into said water. This mixture then enters the impeller buckets and by them has its pressure increased to an amount sufficient to force'i'tthroughv the condenser.

It is' to be particularly noted that the cooling water passes into the centrifugal pump in thesame t irection as the escaping steam and air from theondensing chamber, and that the pressure-energy of the water Ais transformed into the energy of flow by the pump, thereby adapting it as it flows through the suction chamber of the pump to carryvwith it injector-wise the air and steam from said This action results in the creaily pass out with the water. It is also tobe noted that the effectiveness of the pump is increased and its work reduced by reason of the injector actionA of the inflowing cooling water and by reason of the balancing of the water columns, and further that the pump has to lift a uniform mixture.

In accordance with theprovisions of the lpatent statutes, I have described the principle of operation of my invention, together iwith the apparatus which I now consider to re resent the best embodiment thereof but I esire to have it understood that the apparatus shown is onlyillustrative, andthat the invention can be carried out by other means.

icov

What I claim as new and desireto secure by Letters Patent of the United States is,- Y

' 1. In combination, a surface condenser, a centrifugal pump having a suction chamber, an impeller for the pump, a conduit which opens into the vapor space of the condenser and conveys the liquid of condensation, vapor and air to the suction chamber of the pump, a means for supplying li uid to the suction chamber of the pump un er pressure wherein the pressure is converted into velocit and the fluid permitted to mix with the Iiquid of condensation, vapor and air prior to being discharged by the impeller, and a conduit receiving the mixture discharged from the pump and conveying it to the condenser for condensing the vapor therein.

2. In combination, a surface condenser, a centrifugal pump having asuction chamber, a receiving chamber in the pump communiesami eating With the interior of the condenser, a conduit which extends from an exterior point through\\\the chamber and conveys cooling water under pressure to the suction chamber of the pump, and a passage around the conduit which conveys the air and remaining steam fromthe receiving chamber into the cooling water.

3. In combination, a surface condenser, a cooling tower, and a single pump which removes liquid of condensation, air, and re-l mainin vapor from the condenser chamber, mixes tiem with cooled Water from thetower, and discharges the mixture through the condenser to the tower.

In witness whereof I have hereunto set my hand this 2 day of Qecember 1907.
