'CONDENSING APPARATUS.

Application filed August a, 1925. Serial No. 47,674.

This invention relates to condensing appa-' ratus of the surface type, the object of the invention being to provide a condenser of large capacity and high efiiciency, While occupying but small floor space.

In accordance with my invention, I arrange two vertical condensers side by side, with a common exhaust chamber between them, these condensers preferably being in- 1 clined so as to approach each other at their lower ends, and I preferably employ a common hot Well for the two condensers arranged between them and below the steam chamber. I thus secure a very compact and efiicint construction of large capacity, and

enable provision to be readily made for uniform distribution of exhaust steam over the tubes of the two condensers.

For a full understanding of the invention,

a detailed description of a construction embod ing all the features of the same in a pre erred form will now be given in connection with the accompanying drawings forming a art of this specification, and the features ormingthe inventionthen be specifically pointed out in the claims.

In the drawings, which show diagranr matically for purpose of illustration a condensing apparatus of a preferred form,-

Figure 1 is a sectional elevation of the apparatus, and p Figure 2 is a cross-section on the broken line 2-2 of Fig. 1.

. Referring to the drawings, the two condensers have the steam chambers A, A and end water chambers B, B',-the condensers being shown as two-pass, with the waterinlets and outlets 10, 11, and the usual banks of vertical-water tubes 12. The condenser is shown as of a' type now well known, with the usual steam'passes 1 for the admission of .ste'am among the tubes, the central air-cooler 2 in the outer portion of the condenser, with the air oil-take passage 3 extending substantially the length of the condenser. through the air cooler and with which is connected the air off-take pipe 13 which is connectedwith the usual dry air pump or other suction apparatus. It Wlll be understood, however, that this arrangement of condenser tubes and air cooler forms no part ofthe present invention, and any other suitable-tubearrangement' and air cooler may be used. It ma be found desirable, in some cases, to male the condenser of less depth, thus providing for less total dimension through the two condenser construction.

The exhaust connection C is preferably common to thetwo condensers and delivers the exhaust steam to an exhaust chamber D arranged centrally between the condensers, the exhaust connection expanding outward by curved portions so as to supply steam over substantially the full length of the condenser tubes, guide vanes 4 arranged in sets arallel with thecondenser being provide so as to form a decreasing steam space between them and distribute the steam over the condenser tubes. The multiplicity of guide vanes shown with comparatively small steam passages between them, are preferably used, so as 'to-divide the steam into comparatively thin streams and thus provide for change of direction of the steam and assure of its proper distribution throughout the condensers without eddies or counter-currents. As shown, the guide vanes I are of angular form, with their entrance edges in line with the exhaust steam flow from exhaust connection G, and their exit ed es normal to the condenser tubes, but the orm of these guide vanes may be varied accordifig to the conditions under which they are used. These guide vanes may be used with con-. densers of other form and arrangement.

Thecondensers are referably \divided into a series.of steam cham bers by transverse partitions 15, three such chambers being shown provided with anoutlet 16 for the water of condensation, these outlets 16 communicab' ing with a common pipe 17 for each con: denser by which the water ofcondensation is delivered to the hot-well.

A singlehot-well E preferably is. used and arranged between the bottom circulating water chambers F, F of the appa-v ratus and on the same level, so that the space between the lower ends of the condensers is utilized for the hot-well, and the vertical space occu ied by the apparatus thus reduced, the ot-well being closed at the top by the bottom wall 18 of the steam chamber D. The hot-well is shown as of a. usualtype receiving the water of condensation from the two ipes 17 --for the respective condensers and eliverin it through the perforated sleeve 5170 the b0 y of water in the hot-well,

from which the water of condensation is taken off by the usual pump through pipe not to be limited to the detail construction or arrangement of parts shown, but that different forms of condensers may be used with the arrangement illustrated, and various modifications in the arrangement may be made by those skilled in the art, within th invention defined by the'claims.

What is claimed is: p

1. The combination with two vertical surface condensers, of a common exhaust chamber between said condensers, and guide vanes at opposite sides of'the steam chamber for distributing the steam over the condensing surfaces.

2. The combination with two vertical surface condensers, of a common exhaust chamber between said condensers, and a multiplicity of guide vanes with narrow steam passages between them at opposite sides of the exhaust chamber for distributing the steam over the condensing surfaces.

3. The combination with two vertical surface steam condensers arranged in an inclined position so as to approach each other at their lower ends, of a common exhaust chamber between saidcondens'ers.

4. The combination with two vertical surface steam condensers arranged in an in- 'clined position so as to approach each other at their lower ends, of a common exhaust chamber between the condensers, and steam guides on opposite sides of the chamber arranged in series parallel with the condensers for distributing the steam over the condensing surfaces.

5. The combination with two vertical surface steam condensers arranged'in an inclined position so as to approach each other at their lower ends, of a common exhaust chamber between the condensers, and a multiplicity of guide vanes with narrow steam passages between them at opposite sides of the chamber arranged in series parallel with the condensers for distributing the steam over the condensing surfaces.

6. The combination with two vertical surface steam condensers arranged in an inclined position so as to approach each other at their lower ends, of a common exhaust chamber between said condensers, and a hotwell between the lower ends of the condensers receiving the water of condensation from both condensers.

7 The combination with two vertical steam condensers arranged in an inclined position so as to approach each other at their lower ends, partitions dividing the condensers into a plurality of condensing chambers arranged longitudinally of the condensers, a water of condensation discharge from each condensing chamber, a common exhaust chamber between said condensers, and a hotwell between the lower ends of the condensers receiving the water of condensation from both condensers.

8. The combination with two vertical steam condensers arranged in an inclined position so as to approach each other at their lower ends, partitions dividing the condensers into a plurality of condensing chambers arranged longitudinally of the condensers, a water of condensation discharge from each condensing chamber, a common exhaust chamber between the condensers, and a. multiplicity of guide" vanes with narrow steam passages between them at opposite sides of the chamber arranged in series parallel with the condensers for distributing the steam over the condensing surfaces.

9. The combination with two vertical condensers, of a common exhaust chamber between said condensers and having its outlets to said condensers transverse of the inlet of steam into the chamber.

10. The combination with two verticah condensers, of a common exhaust chamber between said condensers and having its out- ,lets to said condensers transverse of the inlet of steam into the chamber, and a multiplicity of guide vanes with narrow steam passages between them at the exhaust chamber outlets for distributing the steam over said condensing surfaces.

In testimonywhereof, I have hereunto set my hand.

CHARLES E. LUCKE.
