List Of Tallest Structures In The United States
The height of structures in the United States has been poorly documented. However, the data is a matter of public record, appearing in documents maintained by the Federal Aviation Administration (FAA) and Federal Communications Commission (FCC). This list is populated heavily by antenna Radio masts and towers, masts. The engineering aspects of super-tall masts are highly specialized. Only four companies erect the majority of such architectural structure, structures: Doty Moore Tower Services (Cedar Hill, Texas); Kline Towers (Columbia, South Carolina); LeBlanc Royal Telecom (Oakville, Ontario); and Stainless Inc. (North Wales, Pennsylvania). The design and construction are largely governed by RS222E Electronic Industries Alliance standards. A tall mast costs between $0.7 and $1.1 million to build, while a tall mast costs $2.4 to $4 million. Prices generally vary depending on tower capacity and wind loading specifications. A common misperception is that landmarks such as the Strat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Tallest Structures In The World
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Flue Gas Stack
A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combustion, combusted in an industrial furnace, a power station, power plant's steam-generating boiler, or other large combustion device. Flue gases can also be produced from chemical or physical processes that do not involve combustion, such as Natural-gas processing, natural gas processing. Flue gas from combustion is usually composed of carbon dioxide (CO2) and water vapor, as well as nitrogen and excess oxygen remaining from the intake combustion air. It also contains a small percentage of pollutants such as Atmospheric particulate matter, particulate matter, carbon monoxide, nitrogen oxides and sulfur oxides. The flue gas stacks are often quite tall, up to , to increase the stack effect and di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
