Application filed March 8, 1923. Serial No. 628,598.

To all whom it may concern: I

Be it known that 1, PAUL A. BANonL, a citizen of the United States, and a resident of ,Nutley, county of Essex, and State of or New Jersey, have invented a certain Twin Multijet Condenser, of which the following is a specification, accompanied by drawings. This invention relates to twin low level multi-jet condensers, but more partlcularly to balancing means connected between the twin condenser bodies.

By connecting a balancing pipe between the ejectors one condenser can be started in operation while the other condenser is running and the vacuum breaker on the condenser which is startin will be prevented from blowing, because t e surplus water is drawn out of the throat of the condenser which is running and ejected to atmosphere. By drawing some of the water out through the balancing pipe from the condenser which is started, that condenser may continue to receive water, as the valve on the supply for.

that condenser is opened and in this way sufiicient velocity is built up to cause the condenser'to operate in the normal way.

The advantages of my balancing pipe construction, in addition to those stated, reside in the fact that one condenser can be readily and conveniently shut down when 'not required, as for instance in cold Weather when only one condenser is necessary to hold the same vacuum with cold water; and since all light loads can be carried on one condenser, and when the peak load comes, the other 7 condenser can be thrown into operation; the complete outfit is more'flexible, because there is in efi'ect two complete units having two supply pumps, and i one unit breaks down or goes out of service for any reason, operation can still be carried on with the other unit; and as a further advantage the balanc-, ing pipe itself affords a means for draining one condenser for starting operation.

The invention is illustrated in the accompanying drawing, which is a longitudinal sectional elevation of a twin low level multijet condenser, artly in diagrammatic form, without such details as are not necessary to the understanding of the invention.

Referring to the drawings, the twin condenser comprises the substantiall circular up-right condenser bodies, A and havmg the usual difiusers or ejectors C and D, and

denser.

tail pieces E and F, which tail pieces are submerged below the water level G in the sum or tank H having the wier J and outlet Q. The tail pieces as shown are provided with the counter-weighted flap valves L and O and as shown, the valve L is open since the condenser A is in full operatlon and the valve 0 is closed since the condenser 4 B is starting to operate. In the present instance, a common unitary connecting steam and water inlet head P extends over, both the condenser bodiesv A and B, as shown in my co-pending application, Serial No. 623,599 filed arch 8, 1923, and this head is provided with theopenin in its lower end adapted tobe fitted to the condenser bodies respectively. The upper opening of the common head is adapted to be fitted to a casing Q which may 1% the casing of a turbine or other prime mover from which the steam is supplied to the con- The connecting head P connects the twin condenser bodies to each other and also connects them with the turbine casing. The head P is provided with the water inlets 1t and S for the condensers A and B respectively and in accordance with my construction each inlet is assumed to be supplied with water from a separate supply pump (not shown). The water passes to the nozzle plates 'l and U having the nozzles V and W formin multi-jets directed towards the throats and Y of the condenser bodies A and B res ectively. Each condenser body is also re erably provided with combining tubes ormed w1th the operating guide vanes Z between which the steam gasses to the jets. The condenser bodies and'B may each be provided with vacuum breakers, one vacuum breaker a being shown on the body B of any suitable or standard construction.

The balancing pipe 6 is shown connecting one condenser body with the other and a valve 0 is preferably provided in the pipe vacuum, but no load. In such'case, the.;con-

or blowing because the surplus-water from 5 the condenser B is drawn ofl' over to the throat of the condenser A. The condenser B can thus keep receiving water and sufiicient velocity will be built up to cause the ejector of the condenser to operate in the m normal way.

I claim:

1. A twin low level multi-jet-condenser,

comprising a, pair of up-ri ht condenser casmgs having difiusers, an ta1l 1eoes pro- 15 vided with valves, said tail pleces being adapted to be surmerged, nozzles within the condenser casings for producing water jets, a balancing pipe connecting one casing with v the other at points above the difi'users, and a valve in. said balancing pipe whereby one 'condensermay be started while. the other is 'difi'users provided with-valves and adapted to be submerged, nozzles within the condenser casings for producmg water ets, a

balancing piping connecting the throat of one condenser casing with the throat of the other condensercasing at points above the diffusers, and a valve in said balancing pi e whereby one condenser may be started while the other is under vacuum and load.

In testimony whereof I have signed this specification.
