ELLIOTT, or PITTSBURGH, PENNSYLVANIA i coNnnNsnR Application filed April 15, 1925, Serial N o. 23,278.
The present'inventio-n relatesy broadly to heat interchange and lliquid treatment, and more particularly as applied to condensers of the type adaptable for use in power plants.
and the like.
In power plant work, it isV desirable to deliver condensate from condensers at temperatures as high as possible, in order to thereby conserve heat-and reduce the amount of heat subsequently required for bringing the condensate to a temperature at which =it may be eiiiciently re-used. A
It is well recognized at the present time that the air dissolved in water is responsible, -t0 alarge extent, for the corrosion which takes .place in power plant equipment, and Vmany eiorts have been made to effect its elimination. The solubility of airin Water is a function of the temperature, the solubilsoity decreasingv as the temperature increases.
From the standpoint, therefore, of deaeration, it is also of material advantage to keep thel temperature of the condensate as high as possible, to thereby proportionately de- 2li;y crease the air content.
It has heretofore been proposed in the art to which the present invention relates to provide condensers of such construction that it is possible to raise the temperature at which ao thecondensate leaves. the condenser. While,
as before stated, the higher temperatures insure a lower air content, I have found that in .order to produce water having a zero oxygen or air content, or extremely low amounts of air it is desirable to subject the condensate not only to higher temperature conditions of the character referred to, but also agitation under such conditions as to facilitate air separation. A l i In operating condensers under such conditions as to produce ahigh condensate temperature, the capacity range of the condenser must be considered 'and conserved. For example, if free steam is utilized for raising the condensate temperature, provision must be made for controlling the volume of steam in such manner that an excess will not be` supplied to any zone of the condenser in such manner -as to effect an overloading thereof with a' consequent diminution in the ability of the condenser to perform that work for which it was designed.
The present invention, therefore, has for certain of its objects the provision of a condenser operating to produce not only a high temperature condensate, but a condensate substantially free from dissolved or entrained air, and at the same time operating under' such conditions that the capacity of the condenser is not impaired.
In thel accompanying drawings there is shown for purposes of illustration only, apreferred embodiment of the present inven-. tion, it being understood that the drawings do not denne the limits of my invention asV changes in the construction and operation disclosed therein may be made without departing either from the spirit of the invention or the scope of my broader claims.
In the drawings:
Figure l is a vertical line I-I of Figure 2;
Figure 2 is a longitudinal sectional view along the line II-II of Figure l, certain of the parts in both figures being shown in elevation;
Figure 3 is a detail sectional view on an enlarged scale, illustrating a portion of the bottom of the condenser, and
Figure 4L is a View illustrating in perspective a skeleton of the interior construction of the condenser.
In the illustrated embodiment of the invention, lI have shown a condenser of the general construction disclosed in the patent t0 Raymond N. Ehrhart, N o, 1,522,290 granted January 6, 1925. It will be understood, however, that theadvantages of the invention are not limited to a condenser of this type, but that it is adapted toa Wide variety of different condensers. Y
In carrying out the present invention there may be.Y provided a condenser of any desired construction, herein shown as having a casing 2 carrying a plurality of longitudinally extending tube banks or tube nests 3. The condenser may be provided with one or more headers 4, as well understood in the art, for controlling the delivery or discharge of cooling waterto the tubes.

These tubes will be eiective t'or abstracting any further heat both from the vapor and from thegases, thereby preventing the Waste of heat through the oiltalre li.
n This automatic control ot the heating steam for the condensate is thus particularly advantageous, as it not only prevents liooding ot the condenser, but also always insures a suin- Ycient supply oi steam to raise 'the temperature of the condensate to the c esired point.
'Efficient deaeration requires the maintenance of definite temperature and pressure conditions. The heater automatically operates to maintain these conditions, and thereby insures at all times the release oi'l air and gas from the condensate.
The construction described is further advantageous in that the flow of steam causes any released air to be swept from the compartment Tinto the compartment thereabove. The construction is such as to produce a counter flow ot condensate and steam of such nature that the steam tirst contacts With the condensate in the compartment T and later contacts with the condensate in the compartment l, all or the steam supplied to the coinpartment Lihovvever, being delivered 'trom the compartment T. This construction insures a condition in Which the major heating I, the condensate being delivered s h heater to the heater T at a temperature substantially equalto the temperature ot the neat- Ving steam. This operation is advantageous as it relieves the heater T trom any substantial-heatingV duty, and consequently enables it to function eiiiciently as a deaeratoi' diie to the possibility o' maintaining a loiv air tension or partial air pressure therein. By the provision of the heater this partial airv vpressure is maintained below that point Which would obtain it the heater T Were acting singly.
It will be apparent to those skilled in the art, that the advantages of. the present invention arise from the provision of a condenser capable ot delivering deaerated condensate at a high temperature and operating under such conditions that the capacity ot the condenser is not lessened and temperature conditions areA always maintained of such nature as to insure etiicient air removal.,
