CONDENSER.

22) all whom it mag concern:

Be it known that I, RAYMOND 'N. Erm- HART, a citiaen of the United States, and a resident of Edgewood Park, in the county of Allegheny and State of Pennsylvania, have made a new and'useful Invention in proved. condenser in which the condensate is heated to substantially the temperature of the fluid to be condensed.

- discharge port 6 which, as shown,

A further object is to produce a condenser in which improved meansare employed for heating the condensate as it is withdrawn from the shdll of the condenser.

A further object is to produce a condenser, in which simple and effective means are employed for subjecting the condensataleaving the condenser to the heating action of the steam or' hot vapors.

' These and other objects are attained by means of a. condenser embodying the features herein described drawing accompanying and forming a hereof.

The drawing is a diagrannnatic sectional part view of a condenser embodying my invention.

The condenser illustrated includes a nest of tu'bes'2, which is inclosed within a shell 3, and through which cooling water is circulated in the usual manner. The shell is provided with the usual inlet port 4:, the usual air ofi'take port 5, and the usual condensate is located in the bottom of the shell.

In the usual forms of surface condensers the condensate flows directly to a condensate or hot well 7 and is then withdrawn by. a condensate pump 8. In the apparatus illuse trated the condensate delivered through the port 6, first flows into and through a hydrostatic trap 16 and then drops into the condensate or hot well 7. In dropping from the trap lOthe condensate is exposed to and heated by steam which in the illustrated embodiment of the invention is delivered to the hot well 7 through a conduit 12 which Specification of Letters Patent.

Con-- densers, of which the following is a specrfiand illustrated in the Patented Jan. 27, 1920.

steam inlet of the condenser. The trap 10 prevents the steam from the hot well from entering the condenser through the port 6. It will, of course, be understood that there will ordinarily be a slight pressure drop between the inlet l and the hot well 7 which will be sufficient to draw steam through the conduit 12 into the hot well at such a rate as to thoroughly heat the condensate as it drops into the hot well.

As illustrated the trap 10 is so arranged that the condensate in dropping from it enters the hot well in a subdivided state, and consequently is readily heated to the temperature of the steam delivered to the hot well. The interchange oi: heat between the steam entering the hot well and the cooler condensate will of .course occasion a condensation a few simple and inexpensive changes in the construction of the condenser. It will, of course, be understood that the steam from any source may be delivered to the hot well,

but this heating steam is preferably with- ,drawn'from the steampassing to the cooling passages of the condenser.

While I have described and illustrated but one embodiment of my invention, it will be apparent to those skilled in the art that va1 i-ious changes, modifications, additions and omissions may be made in the apparatus de-' scribed and illustrated without departing from the spirit and scope of the invention, as set forth by the appended claims.

WVhat I elaim is:

1. In a condenser, a shell having an inlet port formed therein, cooling elements inclosed by the shell, a hot well, a hydrostatic trap connecting the hot well with the shell through which condensate is drained to the hot well, and means for conducting fluids from the inlet port to the hot well for heat ing the condensate discharged from the trap.

2. A condenser having a steam inlet and a condensate outlet port, means for. bypassing steam around the condenser to the outlet port in order to heat condensate issuing from said port, and means including a hydrostatic trap for preventing steam bypassed around the oondea'ser from entering the condenser through the outlet port.

3. condenser having arondensate outlet port in'the bottom thereof, a. hot Well communicating Withsaid port, means for delivering steam to the hot Well for heating the condensate delivered to the hot well from the condenser, and means including a hydrostatic trap for preventing said steam from entering the condenser through the outlet ort.

4. In a. condenser, a shell having a steam inlet port and a condensate outlet )ort, a 'nest of cooling elements located within the shell, a hot well for collecting the condensate Withdrawnfrom the condenser, a hydrostati trap for delivering the condensate to the hot well in a divided state and for preventing vapors from passing from the hot ered from the condenser into the hot well adapted to maintain a substantially uniform sealing pressure regardless of the condensate supply, and means for subjecting the condensate issuing from the trap to the direct action of steam within the hot Well.

In testimony whereof, I have hereunto subscribed my name this 6th day of ()ctoher, 1917.
