Description
AIR COOLED CONDENSER FAN DECK SUBASSEMBLY
[0001] This application claims priority from U.S. Provisional Application No.
61/638,853, the disclosure of which is incorporated herein in its entirety.
Field of the Invention [0002] The present invention relates to air-cooled condensing systems and more particularly to an air cooled condensing system that maintains thermodynamic efficiency but is much simpler and cheaper in physical installation than the current state of the art air cooled condensing systems.
Background of the Invention [0003] The frame assembly of large multi-street field erected air cooled condensers is a complex, labor-intensive, repetitive and potentially dangerous process. While sizes and relative dimensions vary widely, large scale field erected air cooled condensers often consist of as many as eight or more "streets," each street having four or more fan units or "modules."
Figure 1 shows a portion of a typical air cooled condenser (ACC).

While sizes and relative dimensions vary widely, large scale field erected air cooled condensers often consist of as many as eight or more "streets," each street having four or more fan units or "modules."
Figure 1 shows a portion of a typical air cooled condenser (ACC).
[0004] Frame assembly is generally carried out according to a "stick"
assembly process, where each individual piece of the frame is moved into place, one at a time, either by hand, or with assistance with a crane or lift, and sequentially bolted or otherwise fixed to adjacent pieces. As the frame rises into the air, workers climb up, down, and through already assembled portions of the frame to place and bolt new pieces. Hence, beginning from bottom to top, and from one side to the other, the frame is assembled manually, one piece at a time.
For safety, workers use safety harnesses attached to already-assembled portions of the frame, and the harnesses need to be detached and moved to a different part of the frame and the assembly progresses.

Hence, beginning from bottom to top, and from one side to the other, the frame is assembled manually, one piece at a time.
For safety, workers use safety harnesses attached to already-assembled portions of the frame, and the harnesses need to be detached and moved to a different part of the frame and the assembly progresses.
[0005] The portion of the structure supporting the fans, generally referred to as the fan deck, is generally assembled at ground level, then lifted via crane and placed at its final location, often fifty to ninety feet above ground, depending on the size and design of the ACC. Figure 2 is a view of the fan deck steel work looking up when standing at grade. The fan deck steel work is shown in cross-hatch.
[0006] The steel parts that make up the fan deck are typically shipped from the manufacturing facility to the assembly location loose and singularly in standard sized sea containers. The steel frame parts that make up the fan deck can number up to forty or more pieces, see, e.g., Figure 3. Once they arrive at the site, the parts that make up the fan deck must be shaken out of the sea containers in which they are shipped, sorted, identified, and inventoried (sometimes collectively referred to as the "field shake"), all prior to assembly.
[0007] These steps are laborious, time consuming, and expensive. Indeed, purchasers of ACCs, and the erectors who field assemble the ACCs at site, face very high costs to install them, and one of the contributory factors to the high cost of installation is the amount of labor it takes to do the field shake and the field bolting. In addition, many small pieces get lost and damaged and, as it is difficult to determine whether missing parts were lost at the assembly site or not shipped in the first place, ACC manufacturers often have to resupply both structural steel parts and more bolts at their own cost.
[0008] There have been attempts at manufacturing fan deck subassemblies prior to shipping them to the project site, but such prior art fan deck subassemblies have always constituted corner quadrants. The corner quadrants were too big to ship in standard sea containers and therefore were shipped by break bulk. The corner quadrant design typically included twelve to sixteen pieces due to tie-in steel work that was required to connect each of the four corner quadrants after they were erected.
Summary of the Invention [0009] This invention presents ACC fan deck subassembly designs, systems and methods that will result in substantially less material handling, less ground level field assembly and field bolting, and many fewer lifts with the crane. Accordingly, the present invention will make ACCs more attractive to purchase and erect.
Summary of the Invention [0009] This invention presents ACC fan deck subassembly designs, systems and methods that will result in substantially less material handling, less ground level field assembly and field bolting, and many fewer lifts with the crane. Accordingly, the present invention will make ACCs more attractive to purchase and erect.
[00010] Instead of approximately forty separate fan deck parts being delivered to the field site for assembly into a prior art ACC fan deck, each fan deck according to an embodiment of the invention is assembled from eight subassembly parts which are pre-assembled prior to arrival at the final/field assembly location. According to one embodiment of the invention, the eight subassembly parts include four inner subassembly parts and four outer subassembly parts. Once the eight fan deck subassembly parts are delivered to the site, they are unloaded and bolted together, resulting in significant time and cost savings to the purchaser and erector.
According to embodiments of the invention, while certain work is transferred to the manufacturing facility or other pre-assembly location, labor costs are typically much less expensive in a manufacturing facility or pre-assembly facility as compared to field erection labor costs.
According to embodiments of the invention, while certain work is transferred to the manufacturing facility or other pre-assembly location, labor costs are typically much less expensive in a manufacturing facility or pre-assembly facility as compared to field erection labor costs.
[00011] According to an embodiment of the invention, the ACC fan deck subassembly design and method saves on material costs, as field assembly bolts are replaced with shop welds, so the amount of field assembly hardware, e.g., bolts, nuts, etc., that is required for shipment to the field assembly location is reduced.
[00012] According to an embodiment of the invention, the ACC fan deck subassembly parts are sized to fit into a standard size sea container. According to another embodiment of the invention, the ACC fan deck subassembly parts are sized to fit into a shipping container having outside dimensions of approximately 40 feet in length, 8 feet in width, and 9.5 feet in height. According to another embodiment, the ACC fan deck subassembly parts are sized to fit into a shipping container having outside dimensions of approximately 40 feet in length, 8 feet in width, and 8.5 feet in height. According to another embodiment, the ACC fan deck subassembly parts are sized to fit into a shipping container having outside dimensions of approximately 20 feet in length, 8 feet in width, and 8.5 feet in height.
According to another embodiment, the ACC fan deck subassembly parts do not exceed approximately 39.4 feet in length, and approximately 8.8feet in width. According to another embodiment, the ACC fan deck subassembly parts do not exceed approximately 7.8 feet in width.
According to another embodiment, the ACC fan deck subassembly parts do not exceed approximately 19.3 feet in length.
According to another embodiment, the ACC fan deck subassembly parts do not exceed approximately 39.4 feet in length, and approximately 8.8feet in width. According to another embodiment, the ACC fan deck subassembly parts do not exceed approximately 7.8 feet in width.
According to another embodiment, the ACC fan deck subassembly parts do not exceed approximately 19.3 feet in length.
[00013] According to embodiments of the invention, the need for the loading, delivery, unloading, sorting, and inventory of forty or more different parts is eliminated. According to embodiments of the invention, large subassembly parts are fabricated at a manufacturing facility or pre-assembly facility by welding the separate smaller parts together before shipping to the final assembly/field erection site.
[00014] According to an embodiment of the invention, field erection time is reduced due to the reduced time requirement for assembling only eight subassembly parts into an ACC fan deck as compared to the time requirement for unloading, sorting, inventorying, and field assembling (generally bolting) forty or more parts into an ACC fan deck.
[00015] According to an embodiment of the invention, as much as 80% of the fan deck surface plates can be attached to the subassembly parts at ground level rather than at fan deck level.
[00016] According to an embodiment of the invention, many fewer crane lifts of fan deck parts are required, shortening the rental time and costs associated with crane rental at site.
According to another embodiment of the invention, less work at height is required, resulting in increased safety and time and cost reductions.
