Lignites
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks.

Briquette
A briquette (; also spelled briquet) is a compressed block of coal dust or other combustible biomass material (e.g. charcoal, sawdust, wood chips, peat, or paper) used for fuel and kindling to start a fire. The term derives from the French word ''brique'', meaning ''brick''. Coal briquettes Coal briquettes have long been produced as a means of using up 'small coal', the finely broken coal inevitably produced during the mining process. Otherwise this is difficult to burn as it is hard to arrange adequate airflow through a fire of these small pieces; also such fuel tends to be drawn up and out of the chimney by the draught, giving visible black smoke. The first briquettes were known as culm bombs and were hand-moulded with a little wet clay as a binder. These could be difficult to burn efficiently, as the unburned clay produced a large ash content, blocking airflow through a grate. With Victorian developments in engineering, particularly the hydraulic press, it became possibl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garzweiler Surface Mine, October 2018, -01
The Tagebau Garzweiler is a surface mine (german: Tagebau) in the German state of North Rhine-Westphalia. It is operated by RWE and used for mining lignite. The mine currently has a size of 48 km² and got its name from the village of which previously existed at this location. The community was moved to a section of Jüchen with the same name. The open-pit mine The mine is located west of Grevenbroich and exploitation is progressing towards Erkelenz. Mining was originally limited to the 66.0 km² area ''Garzweiler I'' located east of motorway A 44. Mining in the 48.0 km² ''Garzweiler II'' sector started in 2006 and it will take until around 2045 to fully exploit both sectors. The lignite is used for power generation at nearby power plants such as Neurath and Niederaußem. It is not yet known what effect the plan to phase out all coal-fired power plants in Germany by 2038 will have on the Garzweiler lignite mine system. Traffic Motorways A 44 and A ...

Carbon Dioxide Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

Monticello Steam Electric Station
The Monticello Steam Electric Station was a 1.8-gigawatt (1,880 MW) coal-fired power plant located southwest of Mount Pleasant, Texas in Titus County, Texas. It operated from 1974 to 2018. History Monticello had three units. Unit 1 began operations in 1974, Unit 2 became operational in 1975, and Unit 3, became operational in 1978. Originally, the plant produced electricity by burning lignite from nearby mines in Texas. Later the plant received rail shipments of coal solely from Peabody Energy's Rawhide Mine in the Powder River Basin of Wyoming. The plant was cooled by Lake Monticello, which also offers fishing and recreational facilities. The plant was owned by Luminant, a division of Energy Future Holdings.Luminant (2010)"Monticello Power Plant and Mines."/ref> It was operated by Vistra Energy. Selective non-catalytic reduction (SNCR) systems were retrofitted by Fluor to Monticello's units in 2008. This retrofit complimented the LO-NOx burners already installed at Monticello ...

Luminant
Luminant is a Texas-based electric utility. It is a wholly owned subsidiary of Energy Future Holdings Corporation. Luminant's operations include electricity generation and wholesaling, mining, construction, and development. The company has capacity for the generation of 18,300 megawatts (MW) of electricity in 20 power plants spread across Texas, of which 2,300 MW come from nuclear power generated at the company's Comanche Peak Nuclear Power Plant, 5,800 MW from coal-fired power plants, and the remainder from natural gas-fired plants. Luminant is also a major purchaser of wind power. Luminant also owns and operates three of the five largest coal mines (by production) in Texas: the Beckville Strip, the Three Oaks Mine, and the Oak Hill Strip. The Beckville Mine was mined out in the fall of 2015 and the three drag lines were moved to other mines. The Oak Hill Mine will cease operation in December 2016. In December 2016, 77 miners were laid-off due to the closures. The company extra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latrobe Valley
The Latrobe Valley is an inland geographical district and urban area of the Gippsland region in the state of Victoria, Australia. The traditional owners are the Brayakaulung of the Gunai nation. The district lies east of Melbourne and nestled between the Strzelecki Ranges to the south and the Baw Baw Ranges, part of the Great Dividing Range, to the north. Mount St Phillack () is the highest peak to the north of the Latrobe Valley, due north of Moe. The highest peak to the south is Mt Tassie (), south of Traralgon. The area has three major centres, from west to east, , Morwell and Traralgon, with minor centres including , , , and . The population of the Latrobe Valley is approximately 125,000. The valley draws its name from the Latrobe River which flows eastward, through the valley. According to Les Blake, in 1841 William Adams Brodribb, an early settler, named the river in honour of Charles La Trobe, Lieutenant Governor of the Port Phillip District. A. W. Reed also attr ...

Energy Density
In physics, energy density is the amount of energy stored in a given system or region of space per unit volume. It is sometimes confused with energy per unit mass which is properly called specific energy or . Often only the ''useful'' or extractable energy is measured, which is to say that inaccessible energy (such as rest mass energy) is ignored. In cosmological and other general relativistic contexts, however, the energy densities considered are those that correspond to the elements of the stress–energy tensor and therefore do include mass energy as well as energy densities associated with pressure. Energy per unit volume has the same physical units as pressure and in many situations is synonymous. For example, the energy density of a magnetic field may be expressed as and behaves like a physical pressure. Likewise, the energy required to compress a gas to a certain volume may be determined by multiplying the difference between the gas pressure and the external pressure by ...
