DESCRIPTION

Modular condenser apparatus cooled by air and method CROSSED REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the priority of the US provisional application with serial number 61 / 828,076, filed on May 28, 2013, entitled "MODULAR AIR COOLED CONDENSER APPARATUS AND METHOD".

FIELD OF THE INVENTION

[0002] The present invention relates to a mechanical draft cooling tower that uses air-cooled condenser modules. The cooling tower mentioned above works by mechanical draft and achieves heat exchange between two fluids, such as atmospheric air, usually, and another fluid, which is usually steam or some type of industrial process fluid. The cooling tower mentioned above works by mechanical draft that uses an air current generator, such as a fan or the like.

BACKGROUND OF THE INVENTION

[0003] The cooling towers are heat exchangers of a type widely used to emit low temperature heat to the atmosphere and are normally used in the generation of electricity, in air conditioning installations and the like. In a mechanical draft cooling tower for the applications mentioned above, the air flow is induced or propelled by an air flow generator, such as a propelled impeller, a propelled fan or the like. The cooling towers can be wet or dry. Dry cooling towers can be, either "direct dry", in which the steam condenses directly by means of the air that passes along a heat exchange medium that contains the steam or a type of cooling towers " indirect dry ", in which steam, first, passes through a surface condenser cooled by a fluid, and this heated fluid is sent to a cooling tower heat exchanger where the fluid remains isolated from the air, similar to a car radiator. Air current cooling has the advantage that no losses occur due to water evaporation. Both types of dry cooling towers dissipate heat through conduction and convection, and both moles are currently used. Wet cooling towers provide direct air contact to a fluid that cools. Wet cooling towers take advantage of the latent heat of vaporization, which allows a very efficient heat transfer, but at the cost of evaporating a small percentage of the circulation fluid.

[0004] In order to achieve the required direct air current cooling, the condenser normally needs a large surface area to dissipate thermal energy in the gas or steam and can often pose various challenges to the design engineer. . Sometimes, it may be difficult to efficiently and efficiently direct steam to all interior surface areas of the condenser due to the lack of uniformity in the steam supply as a result of pressure losses in the system ducts and the distribution of speed. Therefore, uniform steam distribution is convenient in air-cooled condensers and is paramount for optimum performance. Another challenge or disadvantage is that, although it is convenient to provide a large surface area, a loss of steam pressure can be generated, which increases the back pressure of the turbine and, consequently, reduces the performance of the power plant. Therefore, it is desired to have a condenser with a strategic design of duct and condenser surfaces that allows a uniform distribution of steam along the condenser and reduces back pressure, while allowing a maximum air flow to flow of cooling along and through the condenser surfaces.

[0005] Another drawback of the current air-cooled condenser towers is that they usually require a high labor intensity when it comes to assembly in the workplace. The assembly of these towers, often, requires a labor delivered, which invests a large number of hours. Consequently, such assembly requires a high intensity of workmanship, so it takes an amount of time and, therefore, can be expensive. Consequently, it is desirable and more efficient to assemble the maximum possible tower structure in the plant or manufacturing center, before proceeding to its shipment to the installation site.

[0006] In the art, it is known that improving the performance of the cooling tower (that is, the ability to extract a greater amount of residual heat on a given surface) can result in an improved total efficiency of a conversion of heat of a steam plant in electric power and / or increases in output power in specific conditions. Likewise, by means of cost-effective manufacturing and assembly methods, the total performance of the cooling towers is also improved in terms of the profitability of manufacturing and operation. Therefore, a cooling tower that is efficient in both respects is desired

to heat exchange properties as regards assembly. The present invention addresses this desire.

[0007] Therefore, it would be desirable to have a modular, mechanical and economical draft cooling tower that is efficient both with regard to its heat exchange properties and with respect to the time it takes to assemble it and the cost to do so. same.

DETAILED DESCRIPTION OF THE INVENTION

[0017] In the following detailed description, reference is made to the accompanying drawings, which is part of this document and illustratively show specific embodiments in which the invention can be carried out. These embodiments are described in sufficient detail to allow those skilled in the art to carry them out, and it should be noted that other embodiments can be used, as well as that structural, logical, procedural and electrical changes can be made. It should be noted that any list of materials or arrangements of elements is offered by way of example only and, in no way, intended to be exhaustive. The progression of the process steps described is an example; however, the sequence of stages is not limited to that established herein and may be changed as is known in the art, with the exception of stages that necessarily occur in a certain order.

[0018] Embodiments described herein disclose a heat exchange system, a support structure for an air-cooled condenser ("ACC") and a method of building a structure of support for an ACC. As described herein, some of these or all modes of realization offer substantial advantages compared to ACC structure in standard A. Among the examples of advantages compared to ACC of structure in A is a reduction in the cost of approximately 25%, an improved constructivity, a greater annual production of the power plant, an improved washability due to the use of a standard shuttle of motorized cleaning, a lower visual impact due to the reduction in height (26 m versus 32.6 m) and a reduction in the area of occupied land, as well as a reduction of the foundations (40 columns versus 48 for ACC of A structure with an equivalent production). This reduction in height is due to the reduced height of the multistats described herein in comparison to the A-type structure beams, which have longer tubes and a greater overall height.

[0019] Specific examples of cost reduction and constructivity improvement include: steam distributors and steam condensate collectors already welded into finned tube bundles in the manufacturing factory; lower total weight of the steel structure (- 25% vs. ACC of structure in A); lower total weight of the ducts (- 25% vs. ACC of structure in A); reduced beam quantity (25% for structure ACCs in A); lower number of steel structure elements to be assembled in the workplace by fixing bolts (- 50% compared to A structure ACC); welding length in the workplace on the reduced ducts (- 50% compared to ACC structure in A); lower number of lifting operations; shorter construction duration; lower amount of human activities at heights due to an increase in

preassembly, which results in an improved overall security level; less need for scaffolding; greater proportion of tubenas and pre-assembled tubena supports in the production factory in the finned tube bundles; a large proportion of the assembly in the workplace is in flat terrain (fixing with delta bolts, union duct, ...); no need for cleaning ladder; and more deliveries in containers.

[0020] Specific examples of higher annual power plant production include: lower back pressure during periods of low ambient temperature (eg, below 9 ° C), which results in higher plant production electric during periods of low temperature; and lower minimum back pressure (62 mbar versus 70 mbar for ACC structure in A), which results in a higher electricity production of power plant annually (+ 0.4% compared to ACC structure in A). More specifically, the back pressure can be reduced, since the heat exchange tubes in the beams (described herein) can be made shorter and more numerous compared to an ACC of A structure. Thus, the area of Total area can be equivalent, while reducing the speed in the tubes. Another additional advantage is that the reduced speed results in a corresponding reduction in the erosion of the tubenas.

[0021] In Figure 1, a top view of a heat exchange system 10 having an air-cooled condenser module 12 is shown, according to an embodiment of the present invention, which is suitable for use with a heat generation installation, such as a power plant 14. As shown in Figure 1, the heat exchange system 10 includes a substructure 20 to support the other elements of the heat exchange system 10, such as a pipeline supply 22, risers 24, manifolds 26, upper distributor 28, coils or beams 30, fan 32 and bell housing 34. In addition, a return pipe 36 is configured to return the condensate to the power plant 14.

[0022] In operation, the power plant 14 generates heat to create steam in order to drive turbines to generate energy in a manner that is generally known to those skilled in the art. After the steam has passed through the turbines, the steam still retains a substantial amount of residual heat that the heat exchange system 10 eliminates, and the condensate is returned through the return pipe 36.

[0023] In Figure 2, an elevation view of the air-cooled condenser module 12 shown in Figure 1 is shown, according to an embodiment of the present invention. As shown in Figure 2, the substructure 20 occupies a relatively small area, which results in a large open space below the air-cooled condenser module 12.

[0024] In Figure 3, a cross-sectional view of the air-cooled condenser module 12 shown in Figure 1 is shown, according to an embodiment of the present invention. As shown in Figure 3, the supply pipe 22 is shown with a reduction in size as it progresses along the air-cooled condenser module 12. Generally, as the riser tubes 24 send steam from the supply pipe 22 to the upper distributor 28 and the beams 30, the size of the supply pipe 22 is reduced accordingly.

[0025] In Figure 4, a perspective view of the air-cooled condenser module 12 shown in Figure 1 is shown, according to an embodiment of the present invention. As shown in Figure 4, the manifolds 26, the upper distributor 28 and the beams 30, as well as the fan 32 and the bell housing have been removed for reasons of clarity to show the substructure 20. In the following figures 5- 16, a sequence of the construction invention is illustrated for the air-cooled condenser module 12, according to an embodiment.

[0026] In Figure 5, a bracing between trusses 50 is arranged at a construction site for the air-cooled condenser module 12 shown in Figure 1. Bracing between trusses 50 is configured to support one of the modules of air-cooled condenser 12 on four legs 52. In a usual construction, a foundation is arranged in the ground below each of the legs 52.

[0027] In Figure 6, a perspective view of a conduit 60, the riser tubes 24 and an intermediate reinforcement 62 for the air-cooled condenser module 12 shown in Figure 1 is shown, according to an embodiment of the present invention. As shown in Figure 6, riser tubes 24 and conduit 60 can be pre-assembled in a manufacturing facility and sent by container to the construction site. Similarly, intermediate reinforcement 62 can be pre-assembled in a manufacturing facility and sent by container to the construction site. This and other preassembly described in this document facilitate a reduction in labor costs and an improvement in the quality of construction. For example, in the production facility, welders can protect themselves from rain and other elements that can, in any other way, reduce welding quality. However, in other embodiments, the riser tubes 24 can be fixed to the duct 60 after being placed on the substructure 20.

[0028] In Figure 7, a perspective view of a conduit 60, riser tubes 24 and reinforcement is shown

intermediate 62 assembled for the air-cooled condenser module 12 shown in Figure 1, according to an embodiment of the present invention. In one embodiment, the assembly can be carried out on the ground at the construction site or at the manufacturing facility. In Figure 8, the conduit 60, riser tubes 24 and intermediate reinforcement assembled 62 are shown, arranged on the bracing between trusses 50 for the air-cooled condenser module 12 shown in Figure 1. For example, conduit 60 , riser tubes 24 and intermediate reinforcement 62 assembled can be lifted by a crane and arranged on the bracing between trusses 50.

[0029] In Fig. 9, a plurality of transverse structures 90 are arranged on the conduit 60, riser tubes 24 and intermediate reinforcement assembled 62, arranged on the bracing between trusses 50, for the air-cooled condenser module 12 shown in Fig. 1. For example, transverse structures 90 can be welded or bolted to bracing between trusses 50 after lifting by crane.

[0030] In Figure 10, a perspective view of a transverse reinforcement 100 for the air-cooled condenser module 12 shown in Figure 1 is shown, according to an embodiment of the present invention. The intermediate frame 100 can be pre-assembled in a manufacturing facility and sent by container to the construction site. In Figure 11, the intermediate reinforcement 100 attached to the transverse structures 90 on the conduit 60, riser tubes 24 and assembled intermediate reinforcement 62, arranged on the bracing between trusses 50, is shown for the air-cooled condenser module 12 which is shown in Figure 1. For example, the transverse reinforcement 100 can be welded or bolted to the transverse structures 90 after being lifted by the crane.

[0031] In Figure 12, a perspective view of a longitudinal reinforcement 120 for the air-cooled condenser module 12 shown in Figure 1 is shown, according to an embodiment of the present invention. The longitudinal reinforcement 120 can be pre-assembled in a manufacturing facility and sent by container to the construction site. In Fig. 13, the longitudinal reinforcement 120 attached to the transverse reinforcement 100 is shown. For example, the longitudinal reinforcement 120 can be welded or bolted to the transverse reinforcement 100 after being lifted by the crane.

[0032] In Figure 14, a perspective view of a bridge 140 for the air-cooled condenser module 12 shown in Figure 1 is shown, according to an embodiment of the present invention. In Fig. 15, the bridges 140 are connected to the transverse reinforcements 100 on the bracing between trusses 50. For example, the bridges 140 can be welded or bolted to the transverse reinforcement 100 after being lifted by the crane.

[0033] In Figure 16, a perspective view of a partial placement of the manifolds 26 arranged on the riser tubes 24 is shown. The manifolds 26 connected to the upper distributors 28, which supply steam to the beams 30, are shown. Delta 160 is an assembled set of top distributors 28 and 30 beams.

[0034] Referring now to Figure 17, the air-cooled modular condenser module 12 on a simplified substructure is illustrated. The air-cooled condenser module 12 generally includes a plenum 170 having an air current generator or fan disposed in a fan deflector or inlet hood 34 and the substructure 20 is shown in a simplified form for reasons of clarity The air-cooled condenser module 12 also includes multiple deltas of type A geometry, each indicated as 160. Each delta 160 comprises two assemblies of tube bundles 30 with a series of finned tubes to direct heat transfer. The deltas 160 will be analyzed below, in greater detail.

[0035] Referring now to Figures 18 and 19, schematic side views of the air-cooled condenser module 12 are depicted. As illustrated specifically in Figure 18, the air-cooled condenser employs riser tubes 24 that are welded to the conduit. of main steam 22. The riser tubes 24 are connected to a steam distributor 28 that operates to maintain the most constant steam flow rate. This configuration described above is part of the type A 30 capacitor beams, which are shipped as a unit from the factory, which will be analyzed in greater detail below. The condenser beams 30, preferably, are welded to the riser tubes 24 by means of a transition piece 26 to accommodate the geometry of the steam distributor.

[0036] Referring now to Figure 20, a delta 160 is illustrated. As shown, each delta 160 is composed of two sets of individual heat exchange beams 30, each of which has a series of fin tubes . The individual tubes have a length of approximately two (2) meters, while the beam length is approximately twelve (12) meters. As illustrated, each set of beams 30 is located inclined with respect to the other to form the type A configuration of delta 160. Although the bundle sets 30 can be located at any desired angle, they are preferably located in a angle of approximately twenty degrees (20 °) to approximately thirty degrees (30 °) from a vertical plane and of

approximately sixty degrees (60 °) to approximately seventy degrees (70 °) from a horizontal plane. More specifically, beam assemblies 30 are located twenty-six degrees (26 °) from a vertical plane and sixty-four (64 °) from a horizontal plane.

[0037] Each of the bundle assemblies 30 is assembled prior to shipping, where each comprises a transition piece from upstream to manifold 202, a steam distributor 204, fin tubes 206 and steam condensate collectors 200 As can be seen in Figure 17, due to the modular design and orientation of the beam assemblies 30, the air-cooled condenser design 10 has approximately five (5) times more tubes than in comparison with the usual designs. Likewise, the embodiments of the present invention not only use five (5) times the tubes, but also use condenser tubes that have a much shorter length. As a result of the design and orientation mentioned above, the vapor velocity that travels through the tube bundles 30 is reduced as a result of the increase in the number of tubes in combination with the reduced tube length and, consequently, is reduced the loss of vapor pressure in deltas 160, which makes the air-cooled condenser 10 more efficient.

[0038] Normally, the turbine back pressure of an air-cooled condenser or the like is limited by the maximum vapor velocity in the tubes (to limit erosion), where the vapor velocity increases with a decrease in the back pressure (due to vapor density). Consequently, due to the addition of tubes according to the present invention, the steam is still maintained at the maximum allowable steam rate but at a lower back pressure. The other limitation that addresses the current delta design is that the pressure at the exit of the secondary beams cannot be less than the capacity of the ford group. This pressure is normally the result of turbine back pressure less pressure loss in the ducts less pressure loss in the tubes. Consequently, due to the reduction of pressure loss in the tubes, the allowable turbine back pressure is lower with delta design 160.

[0039] Also, the beam design described above also reduces the pressure loss in the individual delta 160. For example, the heat exchange that occurs through deltas 160 depends on the heat exchange coefficient, that is, The average temperature difference between air and steam and the exchange surface. Due to the reduction in pressure loss as described above, the average pressure (average between the inlet pressure and the outlet pressure) in the exchanger is higher with the design of the current condenser configuration 12. Said of another Thus, when the steam is saturated, the average steam temperature is also higher for the same heat exchange surface, which results in an increase in heat exchange.

[0040] Referring now to Figure 21, a transport container is illustrated, generally referred to as 210. As the name implies, the transport container 210 is used to transport the beams 30 from the manufactures to the job site. As illustrated, the condenser beams 30 are manufactured and assembled at the factory with the steam distributor 204 and the respective steam condensate collectors 200. Although five (5) illustrated beams appear, located in the transport container, a smaller or larger quantity of individual beams can be sent per container depending on the need.

[0041] Alternatively, the embodiments described above herein employ tube bundles manufactured and assembled prior to shipment having steam distributor 204 and steam condensate collectors 200; Beams of alternative embodiments may not include a distributor before shipping. More specifically, in such embodiments, the tube bundles can be sent without steam distributors 28 attached thereto. In such embodiments, the tube bundles 30 can be assembled on the ground to form the type A configuration, as discussed above. However, instead of using two steam distributors, this alternative embodiment can employ a single steam distributor where the only steam distributor extends along the "vertex" of the A configuration.

[0042] Referring now to Figure 22, a flow chart is illustrated, which schematically depicts the assembly steps of the air-cooled condenser tower 12. As described above, the individual tube bundles 30 are they are mounted before being sent to the workplace, which is referred to by the number 212. Each set of individual beams 30 includes a plurality of fin tubes 206 together with a steam distributor 204 and steam condensate collector 200. As discussed above in relation to the previous figures in the specification, the beam assemblies 30 are prefabricated at the factory before placing the individual bundle assemblies 30 in the shipping container 210, identified by number 42. Next , shipping containers 210 are sent to the construction field site.

[0043] Next, the delta, usually indicated as 160, is assembled in the field, as identified with the numbers 216 and 218. As described above, although the beams can be located at any desired angle, they are preferably located at an angle (y) of approximately twenty degrees (20 °) to approximately thirty degrees (30 °) from a vertical plane and at an angle (x) of approximately sixty degrees (60 °) to approximately seventy degrees (70 °) from a horizontal plane. More specifically, you make them

they are located twenty-six degrees (26 °) from a vertical plane and sixty-four (64 °) from a horizontal plane. As indicated by the number 220, a single delta of type A 160 formed by two sets of beams 30 to form the A configuration is illustrated. The sets of beams 30 hold each other autonomously in this configuration.

5

[0044] Referring now to the air-cooled condenser module 12, which is referred to by number 220, is represented by the use of five deltas 160. As discussed above, the air-cooled condenser represents an improvement compared to the current types of air-cooled condensers and has a high level of "prefabrication", which is equivalent to a reduction in the cost of

10 installation and installation time. Likewise, the design described above reduces pressure loss, so that a more efficient heat exchange apparatus is disclosed.

[0045] Tables 1 and 2, which appear below, show the number of parts used for a multi-module of 32 modules and for an A-structure ACC of 30 modules, designed for the same function. It gives a

15 drastic decrease in parts, which translates into a considerable reduction in construction work and construction time.

Total mounting parts for ACC of 30 modules (2 units of 15 modules) | 5148

[0046] As shown in Tables 1 and 2, the multi-access ACC of an embodiment set forth herein includes less than half of the parts of an ACC of comparable conventional A structure (2125

5 parts versus 5148 parts). This reduction in the number of parts entails a corresponding reduction in labor costs, construction time and the like.

[0047] The numerous features and advantages of the invention are apparent from the detailed report and, therefore, it is intended, by the appended claims, to cover all such features and

10 advantages of the invention that fall within the true spirit and scope of the invention. Likewise, since numerous modifications and variations could easily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation that have been illustrated and described; for example, a forced draft air cooled condenser has been illustrated, but an induced draft design can be adapted to obtain the same benefits and, consequently, all suitable modifications and equivalents 15 that fall within the scope of the invention, as described in the appended claims.
