Bull Run Fossil Plant
Bull Run Fossil Plant, commonly known as Bull Run Steam Plant, is a 889 megawatt ( MW), coal-fired electric generating station owned and operated by the Tennessee Valley Authority (TVA). The plant is the only coal fired power plant ever constructed by TVA with one unit, and is expected to close in 2023. Location Bull Run Plant is located on , in the Claxton community of Anderson County, Tennessee, on the north bank of Bull Run Creek, directly across the Clinch River (Melton Hill Lake) from Oak Ridge, Tennessee. History Construction began on April 2, 1962 and was completed on June 12, 1967, when the plant began commercial operation. In August 2018, TVA began studying whether to retire Bull Run. On February 14, 2019, the TVA board of directors voted 5-2 to close Bull Run by December 2023, as well as the remaining coal unit at Paradise in Kentucky by December 2020. High operational costs and low capacity factor were its factors in their decision. Units and operating parameters T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coal-fired Power Stations In Tennessee
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 1967
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Power Stations In Tennessee
The U.S. state of Tennessee receives its power from a variety of sources. The Tennessee Valley Authority (TVA) is the primary utility in Tennessee which generates electricity and sells it to hundreds of local utilities and industrial customers. Like most of the US, the sources used to generate power in Tennessee have changed substantially in the last decade. Coal's share of power has declined from nearly 60% in 2008 to about 25% in 2018, while natural gas has increased significantly. Tennessee is home to the two newest nuclear reactors in the US at Watts Bar Nuclear Plant, unit 2 being the first to begin operation in the 21st century. After Watts Bar Unit 2 began operation in late 2016, nuclear power passed coal as the top source of electricity. In November 2018 natural gas produced more power than coal for the first time in Tennessee. Tennessee is home to the third largest pumped-storage hydroelectric facility in the US, and has the third highest net generation of hydroelectric pow ...

Wet Scrubber
The term wet scrubber describes a variety of devices that remove pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants. Design The design of wet scrubbers or any air pollution control device depends on the industrial process conditions and the nature of the air pollutants involved. Inlet gas characteristics and dust properties (if particles are present) are of primary importance. Scrubbers can be designed to collect particulate matter and/or gaseous pollutants. The versatility of wet scrubbers allow them to be built in numerous configurations, all designed to provide good contact between the liquid and polluted gas stream. Wet scrubbers remove dust particles by ''capturing'' them in liquid droplets. The droplets are then collected, the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfur Dioxide
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula . It is a toxic gas responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of sulfur- bearing fossil fuels. Structure and bonding SO2 is a bent molecule with ''C''2v symmetry point group. A valence bond theory approach considering just ''s'' and ''p'' orbitals would describe the bonding in terms of resonance between two resonance structures. The sulfur–oxygen bond has a bond order of 1.5. There is support for this simple approach that does not invoke ''d'' orbital participation. In terms of electron-counting formalism, the sulfur atom has an oxidation state of +4 and a formal charge of +1. Occurrence Sulfur dioxide is found on Earth and exists in very small concentrations and in the atmosphere at about 1 ppm. On other p ...

Coal Power In The United States
Coal generated about 22% of the electricity at utility-scale facilities in the United States in 2021, down from 39% in 2014. In 2021, coal supplied of primary energy to electric power plants, which made up 90% of coal's contribution to U.S. energy supply. Utilities buy more than 90% of the coal consumed in the United States. There were over 200 coal powered units across the United States in 2022. Coal plants have been closing since the 2010s due to cheaper and cleaner natural gas and renewables. But environmentalists say that political action is needed to close them faster, to reduce greenhouse gas emissions by the United States to better limit climate change. Coal has been used to generate electricity in the United States since an Edison plant was built in New York City in 1882. The first AC power station was opened by General Electric in Ehrenfeld, Pennsylvania in 1902, servicing the Webster Coal and Coke Company. By the mid-20th century, coal had become the leading ...

Capacity Factor
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind or the sun. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production. The actual energy output during that period and the capacity factor vary greatly depending on a range of factors. The capacity factor can never exceed the availability factor, or uptime during the period. Uptime can be reduced due to, for example, reliability issues and maintenance, scheduled or unscheduled. Other fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chattanooga Times Free Press
The ''Chattanooga Times Free Press'' is a daily broadsheet newspaper published in Chattanooga, Tennessee, and is distributed in the metropolitan Chattanooga region of southeastern Tennessee and northwestern Georgia. It is one of Tennessee's major newspapers and is owned by WEHCO Media, Inc., a diversified communications company with ownership in 14 daily newspapers, 11 weekly newspapers and 13 cable television companies in six states.

Clinch River
The Clinch River is a river that flows southwest for more than through the Great Appalachian Valley in the U.S. states of Virginia and Tennessee, gathering various tributaries, including the Powell River, before joining the Tennessee River in Kingston, Tennessee. Course The Clinch River is dammed twice: by Norris Dam, the first dam built by the Tennessee Valley Authority (TVA); and by the Melton Hill Dam, the only TVA dam with a navigation lock that is not located on the main channel of the Tennessee River. An important tributary of the Clinch River is the Powell River. The Clinch and Powell River drainage basins are separated by Powell Mountain. Tributaries entering the Clinch River below Norris Dam but above Melton Hill Dam include Coal Creek, Hinds Creek, Bull Run Creek, and Beaver Creek. Poplar Creek enters the river below the Melton Hill Dam. History A peninsula located at the mouth of the Clinch River, called Southwest Point, was the site of an early frontier for ...
