CONDENSER.

Specification of Letters Patent.

Patented May 14, 1918.

Application filed December 27, 1915. Serial No. 68,843.

Beit known that l, RALP HELLMER,

waterr of condensation shall beA raised to a relatively high temperature, so that it shall not only retain part of the heat of the steam delivered to said condenser but shall be brought more nearly to the temperature at which it may most economically be returned to the boilerg-the invention contemplating a relatively simple, accessible and comparatively inexpensive form of feed water heating attachment for the condenser.

These objects and other advantageous ends I secure as hereinafter set forth7 refer ence being had to the accompanying drawings, in which,

Figure 1 is a plan of a surface condenser equipped with my invention;

Fig. Ais a longitudinal section on the line Fig. 1; andL Figs. 3 and i are respectively transverse vertical sect-ions on the lines 3-3 and 1 1, Fig. Q.

ln the above drawings 1 represents a main condenser body in the form of an elongated cylindrical structure having at one end a receiving chamber Q to which the steam to be condensed is delivered through an inlet The open end of this structure 2 is closed by a head e and a tube sheet 5 is confined between it and the adjacent end of the body 1. A secondtube sheet 6 is conined between the opposite end of said body and the head 7, and two series of tubes 8 and 9 extend between said tube sheets. Vhile all of said tubes open into the hollow of the head T. those of the series S open into the main portion of the inlet casing 2, while the tubes 9 open into a condensate chamber' 10 formed in said casing by a partition 11. The condenser body 1 is provided with an inlet 13 for cooling water and an outlet 1Q, therebeing mounted transversely in said body a battle 14 whereby such water is compelled to take a more or less tortuous course around the tubes S and 9.

Mounted one above the other within the steam receiving casing 2 are a pair of headf and 18 between which extend two sets of tubes 19 and 20 bot-h communicating with the header 16. The header 15 is divided by a partition 21 into two chambers and 23,

into the first of which open the ,tubes 19. while the second receives the tubes 20. Two

pipes 24 and 25 respectively enter the chambers 22 and 23 and a pipe 26 is so connected tor thechamber 10 as todrain any liquid collecting therein.

The tubes 19 and 2O are so placed in the casinff 2 as yto lie directly in the path of the exhaust steam passing from the inlet 3 to the tubes S and under operating conditions such steam is for the most part condensed in passing through said latter tubes, while the water of condensation together with a small amount of uncondensed steam and non-condensable vapors7 after entering the main head 7, passes ltherefrom into the tubes 9.

In these latter' practically all of the rc' maining steam is condensed and the water of condensation with the non-condensable vapors enter the chamber 10 from which it is drawn through the pipe '26 to a pump. From this latter the water is delivered through the conduit 21 to the chamber 227 and iowing into the tubes 19, passes into the header 16, thence into the tubes 20, chamber 23 and out through the conduit Since the tubes 19 and :2O are bathed in or surrounded by the exhaustl steam before it has been exposed to the relativelycold surfaces of the condenser, the water of condensation passing through them is heated to a temperaturedepending on the pressure and volume of the exhaust steam and when discharged through the conduit 25 may pass direct to a feed pump or to further feed water heaters.

Obviously the heater comprised by the headers 15 and 1G and their associated parts may be inexpensively installed, and owing to its being placed in the steam receiving chamber 2, is easily accessible upon removal of the cover or head Ll. Moreover my device may be applied to a well known form of condenser7 such as that illustrated, without material change thereof.

I claim:-

1. The combination of a surface condenser having a body and a steam receiving casing mounted adjacent thereto; headers in said receiving casing; tubes connecting said headers; with means for delivering liquid to and discharging it from a heater comprised by said headers and tubes.

The combination of a tubular condenser; a steain receiving casing having an inlet and provided with a partition dividing it into two chambers, of which one connnunicates with certain of the condenser tubes and the second With others of said tubes; a header mounted on the partition; a series of tubes connected to said header; and a second header also connected to the tubes to proifide a liquid heater mounted in the path or" steain'iiowing roni the inlet to certain oi the tubes oi' the condenser; with means for supplying liquid to and delivering it from said heater.

3. The combination of a surface condenser having a condensing chamber and a steam receiving casing adj acentthereto; headers in said casing; tubes extending between said headers Within the casing and constituting with the headers a Water heater; With means for bracing the headers to the casing independently of the tubes.

i. The combination of a surface condenser containing a bcd37 and a steam receiving casing mounted adjacent thereto; a header in the casing `Qrovided with tWo chambers; with means including tubular structures connecting said chambers and eX- tending into the receiving casing in position to be heated by the steam flow there through.
