A cylindrical cover plate or baflle- 26 is placed on the inlet end of conduit 26 in spaced relation thereto.
As shown, the partition 14 is provided with a plurality of relatively small apertures 28 and partition 15 is provided with a plurality of similar apertures 29. The apertures 28 in partition 14 are located adjacent to or in the region adjoining'the lowermost of the cooling'tubes 11 and are preferably provided by omitting the desired number of the lowermost cooling tubes and utilizing the tube holes provided in the partition 14 for the omitted tubes. The corresponding apertures or tube holes in partition 15 may be conveniently plugged by means of dummy tubes 30 as shown, preferably having one or both ends plugged, or by any other suitable means. The apertures 29 in partition 15 are preferably located, as shown adjacent to or in the region adjoining cooling tubes positioned higher in the condenser shellthan the lowermost tubes, so that a number of cooling tubes 11 will pass through the zone in compartment 17 which lies intermediate the levels determined by the apertures 28 and 29. I have indicated this zone as 11a. The apertures 29 are preferably provided by omitting the desired number of tubes 11 and the correspond ing aertures or tube holes in the partition 14 are p ugged by dummy tubes 31 as previously described. It will be understood, however, that in lieu of utilizing the apertures 28 and 29 ordinarily provided in the partitions 14 and 15 for the cooling tubes, other apertures may be provided in the partition in the de sired location therein.
As will be readily understood, with the cooling medium entering the right-hand end of the condenser as shown in Fig. 1 and leaving the condenser-at the left-hand end, compartment 18 will be the coldest compartment, or the compartment with the greatest heatabsorbing capacity, compartment 16 will be the hottest, or have the lowest heat-absorbing capacity, and compartment 17 will have a heat-absorbing capacity intermediate that of compartments 16 and 18.
In the operation of the condenser, the vapors to becondensed enter each of the compartments 16, 17 and 18 through vaporinlet 21 and flow over the cooling tubes 11 therein. Because of the difference in the heat-absorbing capacities ofthe several compartments. a greater volume of vapors will ordinarily be condensed in compartment 18 than in compartment 17, and a greater volume will ordinarily becondensed in compartment 17 than v in compartment 16. Therefore there will be a different pressure drop ineach of the compartments.
The pressure at the bottoms of the several compartments will be different, with the pressure at the bottom of compartment 16 greater than that at the bottom of compartment 17, and the pressure at the bottom of compartment 17 will be greater than the pressure at the bottom of compartment 18. Consequently, some of the vapors together with non-condensible gases will flow from compartment 16 to compartment 17 through apertures 28 in partition 14. Because of the presence and location of the apertures 29 in partition 15, the vapors and gases entering compartment 17 through the apertures 28 will flow over the cooling tubes 11 passing through compartment 17 in the zone between the aper tures 28 and 29, that is, the tube section 110, and the greater portion of such vapors will be condensed in compartment 17.
In like manner some of the vapors and gases in compartment 17 will flow through apertures 29 in partition 15 into compartment 18 and will flow over the cooling tubes passing through compartment 18 below the apertures 29, that is, the tube section 11b, in the direction toward the conduit 26 and the vapors will thereby be condensed.
With this arrangement, each of the compartments of the condenser is kept steam rich throughout substantially theentire extent of the compartment and without materially diminishing the pressure necessary at the terminus of each compartment to prevent overcharging of the compartments with vapors and consequent loss of efficiency. In this manner, each of the condenser compartments is caused to absorb all the heat it is individually capable of absorbing and without the use of devices and apparatus that complicate the condenser structure and increase the cost of production and maintenance thereof.
-With a three-compartment condenser having a total cooling surface area of approximately 80,000 square feet, the aggregate area of the apertures in each of the partitions dividing the compartments should preferably be approximately 35 square inches and the total area of the cooling surface placed in the path of the vapors flowing through the apertures in the partitions, or the total cooling area below the uppermost group of apertures, should prefcrably be approximately ten per cent of the total cooling surface area of the entire condenser.
With a three-compartment condenser having a total cooling surface area of approximately 60,000 square feet, the aperture area should preferably be approximately 28 square inches, one having 50,000 square feet, approximately 20 square inches, and 30,000 square feet, approximately 16 square inches.
With a four-compartment condenser having a total cooling surface area of approxi mately 80,000 square feet, the total aperture area in each partition should preferably be approximately 40 square inches, and with a five-compartment condenser having approximately 80,000 square feet total cooling surface, the total aperture area in each partition should preferably be approximately 44 square inches.
While the invention has been shown and described as embodied in a three-compartment surface condenser of the single-pass type, it will be understood that it is equally well applicable to condensers having a larger or a smaller number of compartments as well as to condensers of the multi-pass type. In a condenser with an odd number of compartments, the apertures in the partition separating the hottest and the adjoining compartments are preferably located adjacent the lowermost cooling tubes with the apertures in the succeeding partitions progressing toward the coldest compartment of the condenser, alternately above the lowermost tubes and adjacent thereto. In a condenser having an even number of compartments, the apertures in the partition separating the hottest and adjacent compartments are preferably placed above the lowermost tubes with .the apertures 1H succeeding partitions progressing toward the coldest compartment, alternately adjacent to and above'the lowermost tubes as shown in Fig. 3 to provide a circuitouspath of flow of the vapors over the cooling tubes from the hottest compartment to the gas outlet in the coldest compartment. Fig. 3 shows a four compartment single-pass type of condenser which is in general similar to the condenser shown in Figs. 1 and 2. The condenser has three spaced transversely disposed partitions 40, 41 and 42 which divide the condenser into four compartments indicated respectively 43, 44, 45 and 46, the compartment 43 being the hottest compartment 7 and the compartment 46 being the coldest compartment. As shown, the desired number of cooling tubes 11 are omitted at the desired point above the lowermost row thereof to provide the required number of apertures 47 in partition 40 and the apertures 48 in partition 42. The corresponding tube holes in partition41 are closed by suitable plugs 49. Apertures 50 in partition 41 are provided by omittingthe desired number of tubes from the lowermost row thereof. The corresponding tube holes in each of partitions 40 and 42 are closed by dummy tubes 51 and 52 which are. preferably plugged at each end or by any other suitable means. With this arrangement it is apparent that the vapors flowing from one compartment to another will flow in a circuitous path over cooling tubes in each compartment.
Although the apertures in the several partitions areshown and described as lying substantially in horizontal and parallel planes it will be understood that they may, with ap-.
proximately equal effect, be arranged to lie in vertical planes and/or planes inclined to the vertical so that the path of flow of the Vapors passing through the apertures will be from one side of the condenserv to the other as shown in Fig. 5 or from both sides of the condenser to.the center thereof where two groups of apertures are placed in one partition, one group adjacent each side of the condenser and a single group is located near the center. of the adjacent partition as shown in Fig. 4. Expressed with reference to the longitudinal direction in which the tubes extend between the tube sheets in the condenser, the apertures in the several partitions should be out of alignment with respect to the said longitudinal direction.
Figure 4 is a partial transverse sectional view similar to Fig. 2 with the exception that the section is taken through the gas ofl'take conduit 26 and the partition 15 is broken away atits central portion to show the arrangement and location of the apertures in partition 14. As shown, the apertures 60 in partition 14 are centrally disposed of the partition and are arranged approximately vertically in the lower portion thereof. Partition 15 is provided in its lower portion, with a row of apertures 61 arranged adjacent the left side of the partition and also a row of apertures 62 arranged adjacent the right side of the partition. Apertures 61 and 62 may be arranged in vertical rows, if desired. Vith this arrangement it will'be clear that the vapors flow from the hot compartment 16 through the apertures 60 into compartment 17 and over the cooling tubes therein which are disposed between the zones of apertures 60 and apertures 61 and 62 and thence through the apertures 61 and 62 into compartment 18 and into the gas outlet 26 after having passed over the cooling tubes in compartment 18 which are disposed between the apertures 61 and 62 and the gas ofi'take.
Fig. 5 is a transverse View similar to Fig. 4 except that the partition 15 is broken away at its righthand side and except for the disposition of the apertures in the partitions. In Fig. 5, the apertures 70in partition 14 are disposed at the lower right hand side of the partition and the apertures 71 are disposed at the lower left hand side of partition 15. This arrangement will provide a flowof vapor and gases through the condenser from one side to the other as indicated by the arrows.
