Cannel
Cannel coal or candle coal is a type of bituminous coal, also classified as terrestrial type oil shale. Hutton(1987) Dyni (2006), pp. 3–4 Speight (2012), pp. 6–7 Due to its physical morphology and low mineral content cannel coal is considered to be coal but by its texture and composition of the organic matter it is considered to be oil shale. Han et al. (1999) Although historically the term cannel coal has been used interchangeably with boghead coal, a more recent classification system restricts cannel coal to terrestrial origin, and boghead coal to lacustrine environments. Composition Cannel coal is brown to black oil shale. It comes from resins, spores, waxes, and cutinaceous and corky materials of terrestrial vascular plants, in part from Lycopsid (scale tree). Cannel coal was accumulated in ponds and shallow lakes in peat-forming swamps and bogs of the Carboniferous age under oxygen-deficient conditions. Stach (1975), p. 428 Thus cannel coal seams are shallow and often fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haigh, Greater Manchester
Haigh () is a village and civil parish in the Metropolitan Borough of Wigan, Greater Manchester, England. Historically part of Lancashire, it is located next to the village of Aspull. The western boundary is the River Douglas, which separates the township from Wigan. To the north, a small brook running into the Douglas divides it from Blackrod. At the 2001 census it had a population of 594. History Haigh is derived from the Old English ''haga'', a hedge and means "the enclosure". The township was variously recorded as Hage in 1193, Hagh in 1298, and Haghe, Ha and Haw in the 16th century. Manor Between 1220 and 1230 the manor was part of the Marsey fee. Hugh de Haigh, probably Hugh le Norreys paid 3 marks in 1193–4 for having the king's good will. Richard de Orrell granted land in Haigh to Cockersand Abbey in 1220. In 1282 Hugh le Norreys was lord of Haigh. His daughter Mabel married William Bradshagh and in 1298 they inherited the manors of Haigh and Blackrod from Mabel's fa ...

History Of Manufactured Gas
The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century. The manufacturing process for "synthetic fuel gases" (also known as "manufactured fuel gas", "manufactured gas" or simply "gas") typically consisted of the gasification of combustible materials, usually coal, but also wood and oil. The coal was gasified by heating the coal in enclosed ovens with an oxygen-poor atmosphere. The fuel gases generated were mixtures of many chemical substances, including hydrogen, methane, carbon monoxide and ethylene, and could be burnt for heating and lighting purposes. Coal gas, for example, also contains significant quantities of unwanted sulfur and ammonia compounds, as well as heavy hydrocarbons, and so the manufactured fuel gases needed to be purified before they could be used. The first attempts to manufa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bituminous Coal
Bituminous coal, or black coal, is a type of coal containing a tar-like substance called bitumen or asphalt. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the seams. It is typically hard but friable. Its quality is ranked higher than lignite and sub-bituminous coal, but lesser than anthracite. It is the most abundant rank of coal, with deposits found around the world, often in rocks of Carboniferous age. Bituminous coal is formed from sub-bituminous coal that is buried deeply enough to be heated to or higher. Bituminous coal is used primarily for electrical power generation and in the steel industry. Bituminous coal suitable for smelting iron (''coking coal'' or ''metallurgical coal'' ) must be low in sulfur and phosphorus. It commands a higher price than other grades of bituminous coal (thermal coal) used for heating and power generation. Within the coal mining industry, this type of coal is known ...

Oil Shale
Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens. Based on their deposition environment, oil shales are classified as marine, lacustrine and terrestrial oil shales. Oil shales differ from oil-''bearing'' shales, shale deposits that contain petroleum (tight oil) that is sometimes produced from drilled wells. Examples of oil-''bearing'' shales are the Bakken Formation, Pierre Shale, Niobrara Formation, and Eagle Ford Formation. Accordingly, shale oil produced from oil shale should not be confused with tight oil, which is also frequently called shale oil. Deposits of oil shale occur around the world, including major deposits in the United States. A 2016 estimate of global deposits set the total world resources of oil shale equivalent of of oil in place. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Gas
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. The original coal gas was produced by the coal gasification reaction, and thus the burnable component consisted of a roughly equal molecular mixture of carbon monoxide and hydrogen. Thus, coal gas was highly toxic. Other compositions contain additional calorific gases such as methane, produced by the Fischer-Tropsch process, and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Prior to the development of natural gas supply and transmission—during the 1940s and 1950s in the United States and during the late 1960s and 1970s in the United Kingdom and Australia—almost all gas for fuel and lighting was manufactured fro ...

Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as ...

Hydrogen
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.However, most of the universe's mass is not in the form of baryons or chemical elements. See dark matter and dark energy. Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the universe occurred about 370,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Durham, England
Durham ( , locally ), is a cathedral city and civil parish on the River Wear, County Durham, England. It is an administrative centre of the County Durham District, which is a successor to the historic County Palatine of Durham (which is different to both the ceremonial county and district of County Durham). The settlement was founded over the final resting place of St Cuthbert. Durham Cathedral was a centre of pilgrimage in medieval England while the Durham Castle has been the home of Durham University since 1832. Both built in 11th-century, the buildings were designated as a World Heritage Site by UNESCO in 1986. HM Prison Durham is also located close to the city centre and was built in 1816. Name The name "Durham" comes from the Brythonic element , signifying a hill fort and related to -ton, and the Old Norse , which translates to island.Surtees, R.

Lathe
A lathe () is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working. Lathes can be used to shape pottery, the best-known design being the Potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The workpiece is usually held in place by either one or two ''centers'', at least one of which can typically be moved horizontally to accommodate varying workpiece lengths. Other work-holding methods include clamping the work about the axis of rotation using a chuck or col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lancashire
Lancashire ( , ; abbreviated Lancs) is the name of a historic county, ceremonial county, and non-metropolitan county in North West England. The boundaries of these three areas differ significantly. The non-metropolitan county of Lancashire was created by the Local Government Act 1972. It is administered by Lancashire County Council, based in Preston, and twelve district councils. Although Lancaster is still considered the county town, Preston is the administrative centre of the non-metropolitan county. The ceremonial county has the same boundaries except that it also includes Blackpool and Blackburn with Darwen, which are unitary authorities. The historic county of Lancashire is larger and includes the cities of Manchester and Liverpool as well as the Furness and Cartmel peninsulas, but excludes Bowland area of the West Riding of Yorkshire transferred to the non-metropolitan county in 1974 History Before the county During Roman times the area was part of the Bri ...

Bradshaigh Baronets
The Bradshaigh Baronetcy, of Haigh in the County of Lancaster, was a title in the Baronetage of England. It was created on 17 November 1679 for Roger Bradshaigh, formerly a Member of Parliament for Lancashire. The second Baronet represented Wigan and Lancashire in Parliament. The third Baronet sat as Member of Parliament for Wigan for over fifty years and was Father of the House of Commons. The title became extinct on the death of the fourth Baronet in 1770. He was buried at Wigan Parish Church on 3rd. December 1770. The family seat was Haigh Hall, Haigh, Lancashire. After the death of the fourth Baronet the estate was inherited by his great-niece Elizabeth Dalrymple, wife of Alexander Lindsay, 6th Earl of Balcarres. The house was in the Lindsay family until 1947. The family name is pronounced Bradshaw.
