Aberthaw Power Stations
Aberthaw Power Station refers to two decommissioned coal-fired and co-fired biomass power stations on the coast of South Wales, near Barry in the Vale of Glamorgan. They were located at Limpert Bay, near the villages of Gileston and West Aberthaw. The most recent power station on the site, Aberthaw B Power Station, co-fired biomass and as of 2008 had a generating capacity of 1,560 megawatts (MW). The power station closed on 31 March 2020. The station was the location of a carbon capture trial system to determine whether the technology could be scaled up from lab conditions. The system consumed 1 MW. History The site of the stations was a golf course before the construction of the first station. Aberthaw was constructed by the Central Electricity Generating Board (CEGB) under the chairmanship of Christopher Hinton. It is known as one of the original 'Hinton Heavies', a suite of new 500 MW units procured at the time. Aberthaw "A" Power Station altho ...

Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

Central Electricity Generating Board
The Central Electricity Generating Board (CEGB) was responsible for electricity generation, transmission and bulk sales in England and Wales from 1958 until privatisation of the electricity industry in the 1990s. It was established on 1 January 1958 to assume the functions of the Central Electricity Authority (1955–7), which had in turn replaced the British Electricity Authority (1948–55). The Electricity Council was also established in January 1958, as the coordinating and policy-making body for the British electricity supply industry. Responsibilities The CEGB was responsible for electricity generation, transmission and bulk sales in England and Wales, whilst in Scotland electricity generation was carried out by the South of Scotland Electricity Board and the North of Scotland Hydro-Electric Board. The CEGB's duty was to develop and maintain an efficient, coordinated and economical system of supply of electricity in bulk for England and Wales, and for that purpose to ...

Merthyr Tydfil
Merthyr Tydfil (; cy, Merthyr Tudful ) is the main town in Merthyr Tydfil County Borough, Wales, administered by Merthyr Tydfil County Borough Council. It is about north of Cardiff. Often called just Merthyr, it is said to be named after Tydfil, daughter of Brychan Brycheiniog, King Brychan of Brycheiniog, who according to legend was slain at Merthyr by pagans about 480 CE. generally means "Martyr of the Faith, martyr" in modern Welsh, but here closer to the Latin : a place of worship built over a martyr's relics. Similar place names in south Wales are Merthyr Cynog, Merthyr Dyfan and Merthyr Mawr. History Pre-history Peoples migrating north from Europe had lived in the area for many thousands of years. The archaeological record starts from about 1000 BC with the Celts. From their language, the Welsh language developed. Hillforts were built during the British Iron Age, Iron Age and the tribe that inhabited them in the south of Wales was called the Silures, according to Tacitu ...

Ffos-y-fran Land Reclamation Scheme
The Ffos-y-fran Land Reclamation Scheme is a major opencast coaling operation to the north-east of Merthyr Tydfil in South Wales. The contracted excavator/reclaiming company is Merthyr (South Wales) Ltdprev Miller Argent, which is owned by Gwent Investments Limited, a privately-owned family business based in South Wales. The scheme development is the last part of the East Merthyr Reclamation scheme, and will extract 10 million tonnes of coal over 15 years, the revenues from which will redevelop the current former industrial workings into residential and recreational use. The opencast coal mine has provoked criticism at a local and national scale, including objections on health and safety grounds as to the close proximity of housing to the site, concerns of the despoiling of the landscape, and global concerns of the contribution of coal to climate change. A number of protests have occurred on and around the site. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hirwaun
Hirwaun is a village and community at the north end of the Cynon Valley in the County Borough of Rhondda Cynon Taf, South Wales. It is NW of the town of Aberdare, and comes under the Aberdare post town. At the 2001 census, Hirwaun had a population of 4,851. increasing at the 2011 census to 4,990. The village is on the Heads of the Valleys Road and at the southern edge of the Brecon Beacons National Park. Etymology Hirwaun (also formerly spelled as Hirwain and Herwain) derives from two common Welsh toponyms "Hir" meaning long and "Gwaun" meaning moorland. Writing in 1887, Rev. Thomas Morgan stated that the correct name is ''Hirwaun Gwrgant'', meaning Gwrgan's "Waun". This name comes from its association with Gwrgan ab Ithel (1033 - 1070), a king of Morgannwg who is said to have freely given a portion of the waun (named "Y Waun Hir") to his poor subjects and all other Welshmen for raising corn, and the breeding of sheep and cattle. Morgan further states that in olden times the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tower Colliery
Tower Colliery ( Welsh: Glofa'r Tŵr) was the oldest continuously working deep-coal mine in the United Kingdom, and possibly the world, until its closure in 2008. It was the last mine of its kind to remain in the South Wales Valleys. It was located near the villages of Hirwaun and Rhigos, north of the town of Aberdare in the Cynon Valley of South Wales. History With coal located so close to the surface, it was known by locals to be possible to drift mine coal from Hirwaun common. This activity increased from 1805, until in 1864 the first drift named Tower was started, named after the nearby Crawshay's Tower, a folly built in 1848 and named after Richard Crawshay. In 1941, a new shaft was sunk to a depth of 160 metres. From 1943 until closure, this shaft was used as the main "return" ventilation shaft and for the transport of men. In 1958 Tower No. 3 was driven to meet the No. 4 colliery workings, and was used as the main "intake" airway, conveying coal to the surface and tr ...

Thermal Efficiency
In thermodynamics, the thermal efficiency (\eta_) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the ''coefficient of performance'') is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is fractional as the output is always less than the input while the COP of a heat pump is more than 1. These values are further restricted by the Carnot theorem. Overview In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, Q_, to the device is heat, or the heat-content of a fuel that is consumed. The des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DB Schenker
DB Schenker is a division of German rail operator Deutsche Bahn that focuses on logistics. The company was acquired by Deutsche Bahn as Schenker-Stinnes in 2002. It comprises divisions for air, land, sea freight, and Contract Logistics. History In his biography, then CEO of Deutsche Bahn Hartmut Mehdorn justified the acquisition of international logistics companies with customer demand. In 2000, analysis had shown the 200 largest customers ship up to 60% of their freight abroad. Since the core operating territory had been Germany, customers were lost to competitors with a more compelling international offer. There was no time to grow organically in such markets.Hartmut Mehdorn: ''«Diplomat wollte ich nie werden»''. Hoffmann und Campe, Berlin 2007, , p. 114. This analysis led to the acquisition of Stinnes AG and the associated brand name Schenker. Since December 2007 DB Schenker has been the freight logistics subsidiary of Deutsche Bahn. DB Schenker combines all transp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vale Of Glamorgan Line
The Vale of Glamorgan Line ( cy, Llinell Bro Morgannwg) is a commuter railway line in Wales, running through the Vale of Glamorgan from Barry to Bridgend, via Rhoose and Llantwit Major. Route The Barry branch starts at Cardiff West and runs to Barry Island with a single line branch from Cogan Junction to Penarth. In June 1964, the Vale of Glamorgan line between Barry and Bridgend was closed to passengers by the Beeching Axe, as set out in the report 'The Reshaping of Britain's Railways', but after 41 years, in June 2005, it was reopened to passengers with two new stations at Llantwit Major and Rhoose, and the disused bay platform (now '1A') at Bridgend was reinstated to act as a terminus for the Vale Line. The line itself had been retained for freight traffic to/from the Ford Factory in Bridgend, and to Aberthaw Power Station, as well as to provide a detour for main line trains when the direct Bridgend to Cardiff line was closed.

Rail Transport
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles ( rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Trains Passing In Roath - Geograph
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 iron a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
