CONDENSER.

Original application filed February 1,

My invention relates to vapor condensers and more particularly to condensers adapted for use with air ejection apparatus of the multistage, intercooler type, such as is commonly employed in power plants, and it has for an object to provide apparatus of the character designated which shall be composed of standard units of different sizes, assembled to form a complete condenser organization of any desired capacity.

Another object of my invention is to provide condenser organization assembled from units or elements having the same dimensions at connecting ends but of different ratings or capacities, which units are interchangeable and are capable of ready assembly into condenser organizations of various capacities. These and other objects of my invention will appear more fully in the annexed specification, having reference to the accompanying drawing in which Fig. 1 is a longitudinal section through one element of an ejector embodying a condenser constructed 1n accordance with mymvention;

Fig. 2 is a transverse section through a two-' element inter-condenser, taken on the line IIII of 1; Fig. 3 is a view in section.

taken on line III-HI of Fig. 2; Fig. l is a view similar to Fig. 1, illustrating the application of my invention to thejet type of intercooler, and Fig. 5 is a View partially in elevation, and partially in section on the line VV of'Fig. 4:. 1 1

invention contemplatesthe provision of a condenser assembled from unit elements, consisting generally of a shell member of the same cross-sectional conformation, but dilfering in length to give varying condensing capacities, standard tube plates and standard water boxes. The condensers herein disclosed are shown employed in connection with multiple stage ejectors constructed on the unit plan and which are herein briefly described. r p

In .Figs. 1, 2 and 3 of the drawings, the

'- ejector mechanism comprises a number of ejector units each consisting of a first stage ejector 10, a second stage ejector 20, and an inter-condenser 15 locatedbetween the ejectors 10 and 20. The ejector 10, which is of the well known steam jet type, consists of a T OFFICE. v

nozzle 11 and a combining tube 12, and is adapted to exhaust air and other gases from a manifold 13 connected by a valve 14: to the main condenser. or other apparatus served. Similarly, the ejector 20 consists of v a nozzle 21.and a. combining tube 22 and is adapted to'exhaust air and non-condensible vapors from the inter-condenser 15 in a manner'well understood in the art to which my invention relates. The combining tube 12 is connected by a conduit 17 to an inlet 18 of the inter-condenser 15, by means of,

18 and on their lower sides with outlets 23 and drains 241, and is provided with tubes 26 through which cooling water is circulated to effect the condensation of'steam and vapor therein. .The condensate is removed through the drains 24., in any well known manner, to

ejector 20, which exhausts to a discharge manifold 27 in a manner-readily understood v The manifold 27 may be provided with a non-return valve 28, if desired.

The inter-condenser shells sections 19 are I I constructed in two or more sizes, correspond:

ing to the capacities ,of the ejector s; an

assembly of two sizes being shown in Fig. 2. a The sections are similar in construction,

being of the same size and conformation in cross-section and are providedat each end with standard flanges 38; the distinction as to size being securedby difference in length The outside ends ofeach of the two outside sections of the inter condenser assembly carry the tubes 26 which extend throughout the length of the assembled inter-condenser. and by means of which cooling water is circulated.

One end of the assembly is provided with a using two sizes of units, A and B, having water box member 33 having flanges adapted to be bolted or otherwise secured to the standard flanges 38and to clamp the tube sheet 35 in position. The member 83 together 7 with the tube sheet '35 defines a reversing chamberB' -Zby means of which counter-flow of the cooling water is effected, The other end of the assembly is provided with a water box member 41, having an integral partition 40, by means of which the tube sheet a 35 at that end is clamped in place, and which defines, with the tube sheet 35, a pair of chambers 42 to effect the flow of cooling water to and from the tubes 26. The member 41 is provided with a cooling water inlet tarev "provided with standard pipe flanges.

The drain ports 25 are preferably connected to a sectional drain pipe 45.

As mer'nbers constituting an element of my condenser organization are constructed of a uniform size and are provided with standard flanges, any member from one element is freely inter-changeable with a similar member from another element. In assembling the elements of a complete organization to form an apparatus of any desired capacity, the elements are placed in position' nd the flanges 38 of the shell sections are bolted or otherwise secured together in abutting relation. The tube sheets 35 are next installed, carrying between them tubes 7 2'6 ofa proper length to extend through the p'aratus in series;

several shell sections of the assembled ap- The water box members 33 and 41 arethenplaced in position and v the various steam or water connections made on each element, the device is then ready for use.

t will be apparent that by carrying a stock of a comparatively few standard parts, including shell sections of different capacities, the manufacturer is enabled to erect quickly and cheaply a complete condenser organization having widely differing commercial capacities. The flexibility of service' made possible by my invention thus presents an enormous advantage over the methods now in vogue among manufacturers, which necessitates either the building of individual apparatus to order for each installation, or the carrying in stock of a great variety of condensers of different styles, de-

signs and capacities. V

The'adaptability' of my unit-construction may be illustrated in the following example capacities represented by the arbitrarily selected values 1 and 3:

In Figs. 4 and 5 I have illustrated a modification of my invention in which I provide inter-condenser elements of the jet type. The fluid exhausted from the primary ejector 10 passes through the conduit 17 to the inlet 18 of the inter-condenser 15, where it is subjected to the condensing action of water from the nozzles 59 mounted in the nozzle boxes 58. The nozzle boxes 58 are supplied with cooling water through the pipes 60 from a header 61, connected to any suitable source. The inter condenser15 is provided with the baffle plates 56, forming a mixing chamber 57. The non condensible fluids pass through the outlet 23 to the sec 0nd stage ejector 20, while the condensate, plus the cooling water, passes out through the drain pipes 24 to a header 62 from which it is removed by any suitable'means.

While I have shown my invention in several, forms, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes" and modifications Without departing from the s irit thereof, and I desire, therefore that only such limitations shall be placed there= upon as are imposed by the prior art or as are specifically set forth in the appended claims.
